A15137E_DB-HRP_STAT6_Phospho_Antibody_041117
Total cell lysate (15 µg protein) from non-treated (lane 1) and 100 ng/mL of recombinant human IL-4 treated (lane 2) Daudi cells (10 minute treatment) were resolved by electrophoresis, transferred to nitrocellulose, and probed with 1:400 of purified anti-STAT6 Phospho antibody or 1:10000, 1:40000 and 1:100000 of Direct-Blot™ HRP anti-STAT6 Phospho antibody (upper) or loading control GAPDH (clone Poly6314) antibody (lower). Proteins were visualized by chemiluminescence detection using HRP goat anti-mouse IgG secondary antibody for the purified antibody, and HRP donkey anti-rabbit IgG antibody for GAPDH. Lane M is the molecular weight ladder.

Description

STAT6 is a member of the signal transducer and activator of transcription (STAT) family, activating gene expression in response to IL-4 and IL-13 stimulation. Upon cytokine stimulation, the receptor is phosphorylated by the associated Janus Kinases (Jak), followed by recruiting cytoplasmic STAT6. The Tyr641 residue of STAT6 is, in turn, phosphorylated by Jak. Phosphorylated STAT6 forms homodimers, translocates to the nucleus, and regulates transcription of target genes. STAT6 plays crucial roles in differentiation of T helper 2 (Th2) cells, class switch of immunoglobulins in B cells, expression of cell surface markers such as MHC class II, and the development of allergic inflammation.

Verified Reactivity
Human
Antibody Type
Monoclonal
Host Species
Mouse
Immunogen
Human STAT6 peptide phosphorylated at Tyr 641
Formulation
This antibody is provided in 50% glycerol in aqueous buffered solutions with preservatives.
Preparation
The antibody was purified by affinity chromatography and conjugated with HRP under optimal conditions.
Concentration
Lot-specific (to obtain lot-specific concentration, please enter the lot number in our Concentration and Expiration Lookup or Certificate of Analysis online tools.)
Storage & Handling
Upon receipt, the antibody solution should be stored undiluted at -20°C, and protected from prolonged exposure to light.
Application

WB - Quality tested
Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested dilution is 1:10,000 - 1:100,000. The optimal dilution should be determined by titration for each individual assay of interest.

25 µl and 100 µl of Direct-Blot™ HRP antibody can be used for approximately 5 and 20 Western blots, respectively, at the recommended concentration/dilution.

Application Notes

Human STAT6 has three isoforms; the molecular weights are 94, 82 and 74kD. The immunogen (phosphorylated peptide) is shared by these three isoforms. This antibody recognizes STAT6 Phospho (Tyr641) in all three isoforms. The predominant band detected is at 94 kD.

Clone A15137E does not react with mouse.

This clone is not recommended for ChIP (Chromatin Immunoprecipitation) assays (as determined by in-house testing).

AB_2687037 (BioLegend Cat. No. 686015)

Antigen Details

Structure
847 amino acids with a predicted molecular weight of 94 kD. Contains a SH2 domain responsible for phosphor-Tyrosine binding and dimerization.
Distribution

Cytoplasm; translocates to the nucleus when phosphorylated.

Function
STAT6 is a transcription factor, mediating IL-4 and IL-13 signaling. While STAT6 is widely expressed in human tissues, it exhibits elevated expression in peripheral blood lymphocytes, colon, intestine, ovary, prostate, thymus, spleen, kidney, liver, lung, and placenta. Following phosphorylation by Janus kinases, STAT6 translocates to the nucleus where it regulates gene transcription.
Interaction
STAT6 interacts with CBP/p300 and NCOA1. Forms a homodimer or a heterodimer with other STAT family members.
