Stat5 (C-terminal region) Antibody

Product Specifications

Background

The stat proteins function both as cytoplasmic signal transducers and as activators of transcription. Stat5 is activated in response to a wide variety of ligands including IL-2, GM-CSF, growth hormone, and prolactin. Phosphorylation at Tyr-694 is required for Stat5A activation. Stat5 has been found to be constitutively active in some leukemic cell types. Phosphorylated Stat5 is found in some endothelial cells treated with IL-3, which suggests its involvement in angiogenesis and cell motility. Both Stat5A (Tyr-694) and Stat5B (Tyr-699) are independently regulated and activated in various cell types. For instance, both isoforms are activated in response to IFNα in B cells, but only Stat5A is phosphorylated in response to IFNα in HeLa cells.

Stat5 (C-terminal region)

Clonality

Monoclonal

Isotype

IgG1

Clone

M251

Conjugation

Unconjugated

Source

Clone (M251) was generated from a recombinant protein that included amino acid residues in the C-terminal region of human Stat5A.

Applications

Purification

Purified by Protein A.

Dilution

WB (1:300-5000)

Buffer

PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol

Modification

Unmodified

Storage Conditions

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Specificity

The antibody detects a 92 kDa* band corresponding to Stat5A on SDS-PAGE immunoblots of human A431 cells. This sequence has high homology to the conserved regions in rat and mouse Stat5A and B.
