  WB analysis using 80138-2-RR

  Non-treated and GM-CSF (HZ-1002) treated TF-1 cells were subjected to SDS PAGE followed by western blot with 80138-2-RR (Phospho-STAT5A (Ser726)/STAT5B (Ser731) antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. The membrane was stripped and re-blotted with Beta Actin (66009-1-Ig) antibody as a loading control.

Background Information

STAT5 proteins consisting of STAT5A and STAT5B are the main targets of IL-3 signaling. Upon cytokine stimulation, JAK2 phosphorylates STAT5 and the phosphorylated STAT5 proteins dimerize and translocate into the nucleus, where, by binding DNA, they activate target genes including c-fos. In addition to this JAK-catalyzed tyrosine phosphorylation, STAT5 may undergo serine phosphorylation in the carboxy-terminal P(M)SP site in response to prolactin. (PMID: 15795318)
