Esrp-1/2 antibody

Catalog No. ABIN964642

Product Details

Target: Esrp-1/2

Reactivity: Mouse

Host: Mouse

Clonality: Monoclonal

Conjugate: Un-conjugated

Application: Western Blotting (WB)

Specificity: This antibody was purified from tissue culture supernatant by Protein-A chromatography followed by extensive dialysis against the buffer stated above. This antibody reacts with both mouse Esrp-1 and Esrp-2 proteins.  A BLAST analysis of the immunizing protein sequence shows 100% homology with Esrp-1 from mouse and a 91% sequence homology with Esrp-1 from human, pig, rat, opossum, horse, cattle, panda, dog, and chimpanzee .  The binding epitope of this monoclonal antibody has not been mapped

Characteristics: Epithelial splicing regulatory protein-1 (Esrp-1) and Esrp-2 are mRNA splicing factors that regulate the formation of epithelial cell-specific isoforms. They specifically regulate 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-1 and -2 act by directly binding specific sequences in mRNAs. They bind 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-1/2 was produced by repeated immunizations of full length recombinant mouse Esrp-1 fusion protein.
Immunogen Type: RecombinantProtein

Clone: 23A7-C9

Isotype: IgG1

Application Details

Application Notes: This protein-A purified antibody has been tested for use western blotting.  Specific conditions for reactivity should be optimized by the end user.  Expect a band approximately 75.5 kDa in size corresponding to Esrp-1 and 77.4 kDa in size corresponding to Esrp-2 by western blotting in the appropriate cell lysate or extract.
