Interferon lambda-1, also called Interleukin-29(IL-29) is a protein that in Dog Canineas is encoded by the IL29 gene. IL-29 is a member of the helical cytokine family and is a type III interferon. This gene is mapped to 19q13.2. It is a cytokine with immunomodulatory activity. This gene may play a role in antiviral immunity. It can up-regulates MHC class I antigen expression. It is the ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IFNLR1. The ligand/receptor complex seems to signal through the Jak-STAT pathway. IL-29 plays an important role in host defenses against microbes and its gene is highly upregulated in cells infected with viruses. Sample Type: Cell culture supernates, serum, plasma (heparin or EDTA). Intended Use: Sandwich High Sensitivity BioAssay(TM) ELISA kit for Quantitative Detection of Canine IL-29. Sensitivity: <10pg/ml Range: 62.5pg/ml-4000pg/ml Specificity: Recognizes natural and recombinant Canine IL-29. There is no detectable cross-reactivity with other relevant proteins. Test Principle: This Canine IL-29 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune- sorbent assay technology. A monoclonal antibody from mouse specific for Canine IL-29 has been precoated onto 96-well plates. Standards(Expression system for standard: NSO, Immunogen sequence: G20-T200) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Canine IL-29 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Canine IL-29 amount of sample captured in plate. Kit Components: 96-well plate precoated with anti-Canine IFNL1 antibody, 1x plate Lyophilized recombinant Canine IFNL1 standard, 2x10ng/tube Biotinylated anti-Canine IFNL1 antibody, 1x130ul (dilution 1:100) Avidin-Biotin-Peroxidase Complex (ABC), 1x130ul (dilution 1:100) Sample diluent buffer, 1x30ml Antibody diluent buffer, 1x12ml ABC diluent buffer, 1x12ml TMB color developing agent, 1x10ml TMB stop solution, 1x10ml PBS washing buffer Powder for 1000ml, 1x buffer Storage and Stability: Store powder at 4C liquid at -20C. Store other components at 4C. Stable for at least 6 months For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
