Application

Research Sub CategoryTranscription Factors

Western blot: 1:1000-1:2000

Immunoprecipitation: 2 to 4 µg

Whole cell lysate from HeLa , Jurkat, or A431 cells can be used as a positive control for Western Blot and a 91 kDa band can be detected. No reaction to the 84 kDa STAT1beta.

Optimal working dilutions must be determined by end user.

Research CategoryEpigenetics & Nuclear Function

Detect STAT1-α also known as Signal Transducer & Activator of Transcription 1 with Anti-STAT1-α Antibody (Rabbit Polyclonal Antibody), that has been demonstrated to work in IP & WB.

Immunogen

Polyclonal antibody raised against a peptide corresponding to amino acids 712-750 of human STAT1alpha (Schindler et al. 1992). The corresponding sequences of mouse differ from those of the immunogenic peptide by four amino acids.

Specificity

STAT′s (signal transducers and activators of transcripition) are a family of cytoplasmic latent transription factors that are activated to regulate gene expression in response to a large number of extracellular signaling polypeptides including cytokines, interferons, and growth factors. After phosphorylation by JAK tyrosine kinases, STATs enter the nucleus to regulate transcription of many different genes. Among the seven STATs (Stat1, Stat2, Stat3, Stat4, Stat5, Stat5beta, and Stat6), Stat1, Stat3, Stat5alpha, and Stat5beta have a wide activation profile (Leonard et al. 1998; Schindler et al. 1995). STAT1 is activated by many different ligands including IFN family (IFN-alpha, IFN-beta, IFN-gamma, and IL-10), gp130 family (IL-6, IL-11, LIF, CNTF and G-CSF), and receptor tyrosine kinases (EGF, PDGF, CSF-1) (Darnell 1997). STAT1 has two forms, the 91 kDa STAT1alpha and the 84 kDa STAT1beta, which are encoded by the same gene with splicing variant (Schindler et al. 1992).
