Description

Background

Anti-SMAD3 antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. Smad3 (also known as Mothers against decapentaplegic homolog 3 Mothers against DPP homolog 3, Mad3, hMAD-3, JV15-2 or hSMAD3) is a transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinase.   These activators exert diverse effects on a wide array of cellular processes. The Smad proteins mediate much of the signaling responses induced by the TGF-ß superfamily.  Briefly, activated type I receptor phosphorylates receptor-activated Smads (R-Smads) at their c-terminal two extreme serines in the SSXS motif, e.g. Smad2 and Smad3 proteins in the TGF-b pathway, or Smad1, Smad5 or Smad8 in the BMP pathway.  Then the phosphorylated R-Smad translocated into nucleus, where they regulate transcription of target genes.  Based on microarray and animal model experiments, Smad3 accounts for at least 80% of all TGF-ß-mediated response.

Application Note

This affinity purified antibody has been tested for use in ELISA, immunohistochemistry and by western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 48 kDa in size corresponding to Smad3 protein by western blotting in the appropriate stimulated tissue or cell lysate or extract.  This reagent reacts equally to phosphorylated and non-phosphorylated Smad3 by ELISA and western blotting.

Purity/Specificity

SMAD3 affinity-purified antibody is directed against human Smad3 protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification.   A BLAST analysis was used to suggest reactivity with this protein from human, mouse, rat, swine, and chicken sources based on 100% homology for the immunogen sequence. ELISA and western blot show equivalent reactivity against phosphorylated and non-phosphorylated human SMAD3.
