Product Info

• Predicted Species Reactivity: Homo sapiens|Human
• Application: Enzyme-linked Immunosorbent assay-Sandwich
• ELISA Kit Detection Method: Colorimetric
• ELISA Kit Duration: 3h
• ELISA Kit Principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to 2',5'-Oligoadenylate Synthetase 2 (OAS2). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to 2',5'-Oligoadenylate Synthetase 2 (OAS2). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain 2',5'-Oligoadenylate Synthetase 2 (OAS2), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of 2',5'-Oligoadenylate Synthetase 2 (OAS2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
• ELISA Kit Range: 0.78-50ng/mL
• ELISA Kit Reproducibility: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level 2',5'-Oligoadenylate Synthetase 2 (OAS2) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level 2',5'-Oligoadenylate Synthetase 2 (OAS2) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

• Description of Target: Interferon-induced, dsRNA-activated antiviral enzyme which plays a critical role in cellular innate antiviral response (PubMed:10464285, PubMed:9880569). Activated by detection of double stranded RNA (dsRNA): polymerizes higher oligomers of 2'-5'-oligoadenylates (2-5A) from ATP which then bind to the inactive monomeric form of ribonuclease L (RNASEL) leading to its dimerization and subsequent activation (PubMed:10464285, PubMed:9880569, PubMed:11682059). Activation of RNASEL leads to degradation of cellular as well as viral RNA, resulting in the inhibition of protein synthesis, thus terminating viral replication (PubMed:10464285, PubMed:9880569). Can mediate the antiviral effect via the classical RNASEL-dependent pathway or an alternative antiviral pathway independent of RNASEL (PubMed:21142819). In addition, it may also play a role in other cellular processes such as apoptosis, cell growth, differentiation and gene regulation (PubMed:21142819). May act as a negative regulator of lactation, stopping lactation in virally infected mammary gland lobules, thereby preventing transmission of viruses to neonates (By similarity). Non-infected lobules would not be affected, allowing efficient pup feeding during infection (By similarity).
