Product Specifications

Immunogen

This affinity purified STAT3 [p Tyr705] Antibody was prepared by repeated immunizations with a phosphorylated synthetic peptide corresponding to the region of amino acids surrounding tyrosine 705 of human STAT3. (Uniprot: P40763)

Reactivity Notes

A BLAST analysis was used to suggest cross reactivity with Stat3 antibodies from human, mouse, rat, and pig based on 100%sequence homology with the immunogen. Reactivity against homologues from other sources is not known.

Modification

p Tyr705

Specificity

Anti-STAT3 antibody is an affinity-purified antibody and is directed against the phosphorylated form of human STAT3 protein at the Y705. The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide. Anti-Stat3 antibody is specific for the phosphorylated form of the protein. Reactivity with non-phosphorylated Stat3 protein is minimal by ELISA and western blot. A BLAST analysis was used to suggest cross reactivity with Stat3 antibodies from human, mouse, rat, and pig based on 100%sequence homology with the immunogen. Reactivity against homologues from other sources is not known.

Description

This antibody is an affinity-purified antibody and is directed against the phosphorylated form of human STAT3 protein at the Y705. This antibody was affinity purified from monospecific antiserum by immunoaffinity purification. Antiserum was first purified against the phosphorylated form of the immunizing peptide. The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide

Background: STAT3

Stat3 is a member of a group of proteins (Signal Transduction and Activators of Transcription) that act as both signal transducers for cytokines and growth factors, as well as transcription factors (1,2). Stats are activated by tyrosine phosphorylation in response to different ligands, after which they translocate to the cell nucleus (1). Stat3 is constitutively activated in a number of human tumors (3). Stat3 is activated by phosphorylation on tyrosine 705 which induces dimerization, nuclear translocation, and DNA binding While, Stat3-activated transcription seems to be regulated by serine phosphorylation at serine 727 (4)

Long Name

Alternate Names
