IRF3 Antibody

• Catalog Number: orb2636911
• Category: Antibodies
• Description: In the absence of viral infection, IRF3 is maintained as a monomer in an autoinhibited state. Phosphorylation by TBK1 and IKBKE disrupts this autoinhibition leading to the liberation of the DNA-binding and dimerization activities and its nuclear localization where it can activate type I IFN and ISG genes.

Analysis of HuProt (TM) microarray containing more than 19000 full-length human proteins using IRF3 antibody (clone PCRP-IRF3-6C8). These results demonstrate the foremost specificity of the PCRP-IRF3-6C8 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt (TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt (TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.
