Description

Description

The SL-12.1 monoclonal antibody specifically recognizes human Interferon regulatory factor 3 (IRF-3). Viral infection in mammals can lead to the induction of multiple pathways as part of the host defense mechanism. One of the major pathways activated is the JAK-STAT pathway by various interferons (IFNαand IFNβ). These IFNs exert their influence via transcriptional activation of specific target genes involved in antiviral defense, for example the chemokine ISG15 gene or the major histocompatibility complex class I and II molecules. These genes in turn are regulated by the JAK-STAT signaling pathway and through interferon regulatory factors (IRFs). IRFs are a family of transcription factors that possess a broad range of activities. IRF-3 is one of nine members which all share a common DNA binding domain which binds to an IFN stimulated response element (ISRE) found in the majority of IFN-inducible promoters. The IRF3 /gene expresses a 50 kDa protein which is constitutively expressed in all tissues. The protein undergoes post-translational modification as well as dimerization and is translocated from the cytoplasm to the nucleus upon viral infection or exposure to dsRNA.

Alexa Fluor™ 647 conjugates are highly photostable and remain fluorescent over a broad pH range. The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor™ 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor™ 647 cannot be used simultaneously.
