Recommended Dilution Buffer
Immunogen
This antibody was produced by In vivo genetic immunization of IFNAR1 knockout mice with a plasmid encoding the extracellular domain of murine IFNAR1.
Product Concentration
≥ 5.0 mg/ml
Endotoxin Level
< 1.0 EU/mg as determined by the LAL method
Purity
≥95% monomer by analytical SEC
>95% by SDS Page
Formulation
This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.
Product Preparation
Functional grade preclinical antibodies are manufactured in an animal free facility using in vitro cell culture techniques and are purified by a multistep process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.
Storage and Handling
Functional grade preclinical antibodies may be stored sterile as received at 28°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at ≤ 70°C. Avoid Repeated Freeze Thaw Cycles.

Applications and Recommended Usage?
Quality Tested by Leinco
FC The suggested concentration for clone MAR15A3 antibody for staining cells in flow cytometry is ≤ 2.0 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. NOTE: Leinco Technologies suggests using AntiMouse IFNAR1Biotin (With Streptavidin PE; Part No. S211) (Leinco Product No.: I402) for flow cytometry of mouse cells
Additional Applications Reported In Literature ?
B Clone MAR15A3 has a short halflife due to the rapid recycling of cells that express the IFNAR1 receptor. In order to block function In vivo, continual blocking of all compartments is necessary. Therefore, a large loading dose is necessary to saturate all In vivo binding sites and should be maintained to ensure binding site saturation. For In vivo blocking studies, a loading dose of 2.5 mg/mouse, followed by a weekly dose of 0.5 mg/mouse is recommended. The halflife following a 2.5 mg loading dose is approximately 5 days. However, if you fail to saturate the binding sites by injecting a low dose of 250 μg, for example, the half life is only 1.5 days.
WB For Western blotting, the suggested use of this reagent is 1.0 µg per ml (See Data Results) IP
ELISA
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.

Description

Description

Specificity
Clone MAR15A3 recognizes an epitope on mouse IFNAR1.
Background
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 antiviral, antimicrobial, antitumor and autoimmune responses In vivo.
Antigen Distribution
IFNAR1 and IFNAR2 are coexpressed on nearly all cells.
