This phospho-SMAD3 antibodyis to be used only for research purposes and not for diagnostics..
Titration of the phospho-SMAD3 antibody may be required due to differences in protocols and secondary/substrate sensitivity.
If you buy Antibodies supplied by NJS poly they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
Human (Homo sapiens) ; Due to limited knowledge and inability to test the antibody against all known species, we cannot guarantee that no other cross reactivity can occur.
This phospho-SMAD3 antibody was produced from rabbits immunized with a KLH conjugated synthetic phosphopeptide corresponding to amino acid residues surrounding pS208 of human SMAD3.
Aliquot the phospho-SMAD3 antibody and store frozen at -20 deg. Celcius or lower. Cycles of freezing and thawing can denaturate the peptide chains of the antibodies and reduce their sensitivity and/or change their affinity. Prepare aliqotes in such a manner so that freeze-thaw cycles are minimized.
SMAD3, a receptor regulated SMAD (R-SMAD) is a transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinase. SMAD3 is estimated to account for at least 80% of all TGF-beta-mediated response. Activated type I receptor phosphorylates receptor-activated SMADS (RSMADS) at their c-terminal two extreme serines in the SSXS motif. The phosphorylated R-SMAD translocate into nucleus, where they regulate transcription of target genes. SMAD3 signal transduction appears to be important in the rgulation of muscle-specific genes. Loss of SMAD3 is a feature of pediatric T-cell lymphoblastic leukemia, while upregulation of SMAD3 may be responsible for TGFB hyperresponsiveness observed in scleroderma.
