 IFNAR1 组成成分
包被抗体:0.5 mg/mL of mouse anti-IFNAR1 monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 2 μg/mL in PBS before coating. (Catalog: # 13222-MM11)
检测抗体:0.2 mg/mL mouse anti-IFNAR1 monoclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % HRP-protector, pH 7.4). Dilute to working concentration of 0.25 μg/mL in detection antibody dilution buffer before use. (Catalog: # 13222-MM05)
标准品:Each vial contains 95 ng of recombinant IFNAR1. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 5 ng/mL is recommended.
 IFNAR1 检测灵敏度
The minimum detectable dose of Human IFNAR1 / IFNAR was determined to be approximately 78 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
 IFNAR1 产品介绍
The Human IFNAR1 / IFNAR ELISA Pair Set is for the quantitative determination of Human IFNAR1 / IFNAR.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for IFNAR1 / IFNAR coated on a 96-well plate. Standards and samples are added to the wells, and any IFNAR1 / IFNAR present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated mouse anti-IFNAR1 / IFNAR monoclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of IFNAR1 / IFNAR present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.

IFNAR1 研究背景

Interferon-alpha/beta receptor alpha chain (IFNAR1) is a type I membrane protein that forms one of the two chains of a receptor for interferons alpha and beta. Binding and activation of the receptor stimulates Janus protein kinases, which in turn phosphorylate several proteins, including STAT1 and STAT2. The encoded protein also functions as an antiviral factor. Tyk2 slows down IFNAR1 degradation and that this is due, at least in part, to inhibition of IFNAR1 endocytosis. Mutant versions of IFNAR1, in which Tyr466 is changed to phenylalanine, can act in a dominant negative manner to inhibit phosphorylation of STAT2. These observations are consistent with a model in which IFNAR1 mediates the interaction between JAK kinases and the STAT transcription factors.
