The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000 - 1/10000. Detects a band of approximately 90,130 kDa (predicted molecular weight: 64 kDa). Due to extensive glycosylation of the mature molecule; the 90 kDa species is a minor incompletely processed species.|
ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
FunctionAssociates with IFNAR2 to form the type I interferon receptor. Receptor for interferons alpha and beta. Binding to type I IFNs triggers tyrosine phosphorylation of a number of proteins including JAKs, TYK2, STAT proteins and IFNR alpha- and beta-subunits themselves.
Tissue specificityIFN receptors are present in all tissues and even on the surface of most IFN-resistant cells. Isoform 1, isoform 2 and isoform 3 are expressed in the IFN-alpha sensitive myeloma cell line U266S. Isoform 2 and isoform 3 are expressed in the IFN-alpha resistant myeloma cell line U266R. Isoform 1 is not expressed in IFN-alpha resistant myeloma cell line U266R.
Sequence similaritiesBelongs to the type II cytokine receptor family.
Contains 3 fibronectin type-III domains.
modificationsPhosphorylated on tyrosine residues by TYK2 tyrosine kinase.

All lanes : Anti-Interferon alpha/beta receptor 1 antibody [EP899Y] (ab45172) at 1/1000 dilution
Lane 1 : Wild-type (HeLa) whole cell lysate
Lane 2 : IFNAR1 (Interferon Receptor alpha) knockout (HeLa) whole cell lysate
Lysates/proteins at 20 µg per lane.
Predicted band size: 64 kDa
Lanes 1 - 2: Merged signal (red and green). Green - ab45172 observed at 64 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab45172 was shown to recognize Interferon alpha/beta receptor 1 in wild-type WT (HeLa) cells as signal was lost at the expected MW in IFNAR1 (Interferon Receptor alpha) knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and IFNAR1 (Interferon Receptor alpha) knockout samples were subjected to SDS-PAGE. Ab45172 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
