Applications and Recommended Usage?
Quality Tested by Leinco
FC The suggested concentration for clone MAR1-5A3 PE conjugated antibody for staining cells in flow cytometry is ≤ 1.0 μg per 106 cells in a volume of 100 μl or 100μl of whole blood. Titration of the reagent is recommended for optimal performance for each application.
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.


Clone MAR1-5A3 recognizes an epitope on mouse IFNAR1.
IFNAR1 is a type I membrane protein, that in conjunction with IFNAR2, makes up the heterodimeric receptor that binds all type I IFNs, which includes IFN α and β. Binding and activation of the receptor stimulates Janus protein kinases, which leads to the phosphorylation of several other proteins, namely STAT1 and STAT2. IFNAR1 has also been shown to interact with PRMT1 and Tyrosine kinase 2. Type I IFNs are a family of cytokines that have been shown to promote anti-viral, anti-microbial, anti-tumor and autoimmune responses In vivo.
Antigen Distribution
IFNAR1 and IFNAR2 are coexpressed on nearly all cells.
