Background of STAT3

The transcription factor, signal transducer and activator of transcription-3 (STAT-3) is the most pleiotropic member of the signal transducer and activator of transcription (STAT) family of transcription factors and mediates pivotal responses for the cytokine family. The mouse STAT3 gene contains 24 exons and spans 30 kb. The translation initiation codon is in exon 2, and the stop codon is in exon 24. STAT3 is mapped to 17q21. It contributes to various physiological processes. Hepatic STAT-3 signaling is thus essential for normal glucose homeostasis and may provide new therapeutic targets for diabetes mellitus.

Antibody Validation

Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence and ELISA with known positive and negative samples to ensure specificity and high affinity.

4 Customer Q&As for Anti-STAT3 Antibody Picoband™


We are currently using anti-STAT3 antibody PB9511 for rat tissue, and we are happy with the WB results. The species of reactivity given in the datasheet says human, mouse, rat. Is it possible that the antibody can work on feline tissues as well?

Asked: 2020-04-28


The anti-STAT3 antibody (PB9511) has not been validated for cross reactivity specifically with feline tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in feline you can get your next antibody for free. Please contact me if I can help you with anything.
