ESRP2 antibody

Catalog No. ABIN964644

Product Details anti-ESRP2 Antibody

Target: ESRP2 (Epithelial Splicing Regulatory Protein 2 (ESRP2))

Reactivity: Mouse

Host: Mouse

Clonality: Monoclonal

Conjugate: This ESRP2 antibody is un-conjugated

Application: Western Blotting (WB)

Specificity: This product is an IgG fraction antibody purified from tissue culture supernatant by Protein-A chromatography followed by extensive dialysis against the buffer stated above. This antibody reacts with mouse Esrp-2 protein.  A BLAST analysis was used to suggest cross-reactivity with Esrp-2 from mouse based on a 100% homology with the immunizing sequence.  Cross-reactivity with Esrp-2 from other sources has not been determined.

Characteristics: Epithelial splicing regulatory protein 2 (Esrp-2) is an mRNA splicing factor that regulates the formation of epithelial cell-specific isoforms. It specifically regulates the expression of FGFR2-IIIb, an epithelial cell-specific isoform of FGFR2, and also regulates the splicing of CD44, CTNND1, ENAH, 3 transcripts that undergo changes in splicing during the epithelial-to-mesenchymal transition (EMT). Esrp-2 acts by directly binding specific sequences in mRNAs. It binds the GU-rich sequence motifs in the ISE/ISS-3, a cis-element regulatory region present in the mRNA of FGFR2.

Purification: purified

Sterility: Sterile filtered

Immunogen: Anti-Esrp-2 is produced by repeated immunizations of full length recombinant mouse Esrp-2 fusion protein.
Immunogen Type: RecombinantProtein

Clone: 22C5-H7-A6

Isotype: IgG2a kappa

Application Details

Application Notes: Anti-Esrp-2 protein A purified antibody has been tested for use western blotting and shows specific reactivity by with ESRP2 transfected cell lysates..  Specific conditions for reactivity should be optimized by the end user.  Expect a band approximately 77.4 kDa in size corresponding to Esrp-2 by western blotting in the appropriate cell lysate or extract. The antibody shows bands at ~77kD and 70kD and no reactivity is observed in cells transfected with GFP or ESRP1. A starting dilution of 1:1000 is suggested for western blotting.
