Assay Range 0.313 – 20 ng/ml and Detection limit 100 pg/ml.100 Assays. NAD(P)H:quinone acceptor oxidoreductase 1 (NQO1), a multifunctional antioxidant enzyme and exceptionally versatile cytoprotector, both protects the cell from carcinogenic oxidative damage and stabilizes the tumor suppressor p53 protein. At high glycolysis levels NQO1 stabilizes and protects p53 from ubiquitin-independent degradation, a process that is NADH dependent, and also elevates NAD+/NADH levels. NAD+ and NADH play a crucial role in cellular energy metabolism, and a dysregulated NAD+/NADH ratio is implicated in metabolic syndrome. In humans, NQO1 is expressed at high levels in adipocytes and its expression levels are positively correlated with adiposity, glucose tolerance, and liver dysfunction. Thus NQO1 may provide the basis for a new therapy for the treatment of metabolic syndrome. This assay is a sandwich Enzyme Linked-Immunosorbent Assay (ELISA) for quantitative determination of human NQO1 in cells. A monoclonal antibody specific for NQO1 has been precoated onto the 96-well microtiter plate. Standards and samples are pipetted into the wells for binding to the coated antibody. After extensive washing to remove unbound compounds, NQO1 is recognized by the addition of a purified polyclonal antibody specific for NQO1 (Detection Antibody). After removal of excess polyclonal antibody, HRP conjugated anti-rabbit IgG (Detector) is added. Following a final washing, peroxidase activity is quantified using the substrate 3,3’,5,5’-tetramethylbenzidine (TMB). The intensity of the color reaction is measured at 450 nm after acidification and is directly proportional to the concentration of NQO1 in the samples. This ELISA is specific for the measurement of natural and recombinant human NQO1. It does not cross-react with human adiponectin, human RBP4, human Nampt, human vaspin, human progranulin, human resistin, human clusterin, human ANGPTL3, human CTRP5, human IL-33, human leptin, human GPX3, human NMNAT2, human sirtuin 1, human FTO, mouse Nampt, rat Nampt. The assay range is 0.313 – 20 ng NQO1/ml and a detection limit of 100 pg/ml (based on adding two standard deviations to the mean value of the (50) zero standards).

Cell culture media etc.Obestatin (human/mouse/rat) EIA Kit: Colorimetric Assay for Quantitative Determination of Obestatin in Serum, Plasma, Cell culture supernatants etc. Detection range: 0.1-1000 pg/ml. 100 assays.BioVision’s Obestatin Enzyme Immunoassay (EIA) Kit is an in vitro quantitative assay for detecting Obestatin peptide based on the principle of Competitive Enzyme Immunoassay. The microplate in the kit is pre-coated with anti-rabbit secondary antibody. After a blocking step and incubation of the plate with anti- Obestatin antibody, both biotinylated Obestatin peptide and peptide standard or targeted peptide in samples interacts competitively with the Obestatin antibody. Uncompeted (bound) biotinylated Obestatin peptide then interacts with Streptavidin-horseradish peroxidase (SAHRP), which catalyzes a color development reaction. The intensity of colorimetric signal is directly proportional to the amount of biotinylated peptide-SA-HRP complex and inversely proportional to the amount of Obestatin peptide in the standard or samples. This is due to the competitive binding to Obestatin antibody between biotinylated Obestatin peptide and peptides in standard or samples. A standard curve of known concentration of Obestatin peptide can be established and the concentration of Obestatin peptide in the samples can be calculated accordingly. The minimum detectable concentration of Obestatin is 0.1 pg/ml. The detection range for the kit is 0.1-1,000 pg/ml. The intra-Assay reproducibility is CV<10% & inter-Assay is CV<15%.

OPN is a multifunctional, hyperphosphorylated acidic glycoprotein. As a key component of extracellular matrix-associated protein abundantly expressed in bone, OPN is a key regulator of bone mineralization. In addition, OPN is expressed in multiple other cell types including macrophages, smooth muscle cells and hepatocytes. OPN up-regulation occurs upon exposure to pro-inflammatory cytokines (TNF-α, TGF-β etc.) or under pathological conditions such as hypoxia and hyperglycemia. OPN also functions as a chemokine-like protein involved in regulating cell proliferation, inflammatory responses, angiogenesis and metastasis, and is critical in the development of multiple disorders including cardiovascular disease, diabetes, and cancer. The assay employs monoclonal antibody specific for human OPN coated on a 96-well microplate. Standards and samples are pipetted into the wells and OPN present in the sample is bound to the wells by the immobilized antibody. The antibody-captured OPN is then detected by a biotinylated monoclonal antibody. With HRP conjugated Streptavidin and a HRP substrate, amount of OPN in the sample is determined by measuring absorbance of the HRP product at 450 nm with a microplate reader. The sensitivity of the kit is 0.2 ng/ml and detection range is from 0.2 ng to 70 ng/ml. The intra-assay reproducibility as measured by the coefficient of variation (CV) is <5 % & inter-assay CV < 7 %.

Detection Range: 0.2-25.6 ng/ml. 100 assays. BioVision’s p53 Enzyme-Linked Immunosorbent Assay (ELISA) Kit is an in vitro assay for the quantitative measurement of native and recombinant human p53. The p53 protein is encoded by the TP53 gene. It is composed of 393 amino acids but its apparent molecular mass is 53 kDa. p53 binds to a DNA consensus sequence, the p53 response element, and regulates normal cell cycle events by activating transcription of genes involved either in progression through the cell cycle, or causing arrest in G1 when the genome is damaged. It acts as a pivotal suppressor of inappropriate cell proliferation. By initiating suppressive effects through induction of apoptosis, cell senescence, or transient cell-cycle arrest, p53 plays an important role in cancer suppression, developmental regulation, and aging. p53 is found in increased amounts in a wide variety of transformed and tumor cells, where its concentration is increased 5-1000 fold over the concentration in normal cells. Meanwhile, p53 is also frequently mutated or inactivated in about 60% of cancers. The p53 ELISA assay employs an antibody specific for human p53 coated on a 96-well plate. Standards and samples are pipetted into wells and p53 present in the sample is bound to the wells by immobilized antibody. Wells are washed and a biotin-labeled human p53 specific detection antibody is added. After washing away unbound detection antibody, a streptavidin HRP-conjugate is added to the wells. The wells are again washed, a TMB substrate solution is added, and color develops in proportion to the amount of bound p53. Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm. Sensitivity of the kit is 0.1 ng/ml and detection range is from 0.2 ng/ml to 25.6 ng/ml. Recovery within this range is 86.3%. The intra-assay reproducibility as measured by the coefficient of variation (CV) is < 8 % & inter-assay has CV < 12 %.

Stop Solution (ready to use) Serum or plasma Progesterone (human) ELISA Kit: Rapid & convenient colorimetric assay for quantitative measurement of human Progesterone (P4) in serum or plasma. Sensitivity: 0.22 ng/ml. 100 assays. Progesterone is a C21 steroid which is synthesized from both tissue and circulating cholesterol. In males, progesterone is a necessary intermediate for the production of corticosteroids and androgens. In females, progesterone remains relatively constant throughout the follicular phase of the menstrual cycle. The concentration then increases rapidly following ovulation and remains elevated for 4-6 days and decreases to the initial level 24 hours before the onset of menstruation. In pregnancy, placental progesterone production rises steadily to levels of 10 to 20 times those of the luteal phase peak. Progesterone measurements are thus performed to determine ovulation as well as to characterize luteal phase defects. Monitoring of progesterone therapy and early stage pregnancy evaluations comprise the remaining uses of progesterone assays. BioVision’s Progesterone kit is a solid phase competitive ELISA Kit. The samples, and Progesterone enzyme conjugate are added to the wells coated with anti-Progesterone monoclonal antibody. Progesterone in the sample competes with a Progesterone enzyme conjugate for binding sites. Unbound Progesterone and Progesterone enzyme conjugate is washed off by wash buffer. Upon the addition of the substrate, the intensity of color is inversely proportional to the concentration of Progesterone in the samples. A standard curve is prepared relating color intensity to the concentration of the Progesterone.

Assay Buffer ? TMB Substrate ? Stop Solution ? Serum or plasmaProinsulin (human) ELISA Kit: Rapid & convenient colorimetric assay for quantitative measurement of human Proinsulin. 100 assays. Proinsulin is synthesized in the beta cells of the pancreas and is the precursor molecule for insulin. Most proinsulin is converted to insulin and C-Peptide, which are secreted in equimolar amounts into the blood. About 15% is not converted and is released as proinsulin. The biological activity of proinsulin is only about 10% of Insulin, but the half-life of proinsulin is three times as long as insulin. The level of proinsulin in serum can be a reflection of ? cell status. Both IDDM and NIDDM are characterized by dysfunction of the pancreatic beta cells. Elevated proinsulin levels have been noted at the onset of IDDM and in healthy siblings of IDDM patients. Proinsulin levels may also be increased in patients with established NIDDM. Increased levels of circulating proinsulin are found in older patients, pregnant or obese diabetics, patients with insulinomas, functional hypoglycemia and hyperinsulinemia, a rare syndrome. Because the structure of proinsulin is similar to insulin, proinsulin may be detected as immunoreactive insulin in the insulin assay. Immunoreactive insulin levels are generally determined in conventional RIA's, which overestimate the insulin level because the methods use antibodies, which cross, react with proinsulin. By calculating the molar ration of proinsulin to true insulin (P/I), a better assessment of beta cell function can be made. BioVision’s Proinsulin kit is a solid phase enzyme-linked immunosorbent assay (ELISA) based on the sandwich principle. The microtiter wells are coated with a monoclonal antibody directed towards a unique antigenic site on a Proinsulin molecule. An aliquot of sample containing endogenous Proinsulin is incubated in the coated wells. After washing off the samples in a second step an enzyme conjugate, which is an anti-Proinsulin antibody conjugated with horseradish peroxidase is incubated in the wells. After incubation the unbound conjugate is washed off with wash solution. Having added the substrate solution, the intensity of color developed is proportional to the concentration of Proinsulin in the sample.
