Catalog no.: ABIN361505

Additional Information

Format: Affinity-purified

Description: Interferons are widely used therapeutic agents because of their anti tumor and antiviral effects and because of their modulatory effects on the immune system (Biron, 2001, Kirkwood, 2002). These cytokines produce their effects by binding to the Type 1 Interferon-a Receptor (IFNAR1). Down regulation of this receptor plays a key role in determining the magnitude and duration of cytokine signaling. This down regulation is thought to be influenced by phosphorylation of Serine 535 and 539 in the IFNAR1 (Kumar et al., 2003). Anti-Phospho Ser535,539 IFNAR1 Western blot of immunoprecipitates from HEK 293 cells transfected with 1. Mock, 2. IFNAR1 WT, and 3. IFNAR1 S535A and S539A mutants showing specific immunolabeling of the ~110k to ~130k IFNAR1 WT. The immunolabeling is absent in IFNAR1 Ser535 and Ser539 mutants (Control). The immunolabeling is blocked by the phosphopeptide (Phos) used as the antigen but not by the corresponding dephosphopeptide (Dephos).

Specificity: Specific for IFNAR1 protein phosphorylated at Ser535,539.

Application Details

Application Notes: Recommended Dilution: WB: 1:1000 IHC: 1:1000 Quality Control: Western blots performed on each lot.

Purification: Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.

Storage: Store at -20 °C, stable for 1 year

Restrictions: For Research Use only
