This SMAD2/3 antibodyis to be used only for research purposes and not for diagnostics..
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.
An amino acid sequence from the C-terminus of human SMAD2/3 (QSPNCNQRYGWHPATVC) was used as the immunogen for this SMAD2/3 antibody (100% homologous in human, mouse and rat).
The stated application concentrations are suggested starting amounts. Titration of the SMAD2/3 antibody may be required due to differences in protocols and secondary/substrate sensitivity.
Human (Homo sapiens), Mouse (Mus musculus), Rat ; Due to limited knowledge and inability to test the antibody against all known species, we cannot guarantee that no other cross reactivity can occur.
After reconstitution, the SMAD2/3 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store 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. Avoid repeated freezing and thawing.
SMAD proteins transmit signals from transmembrane serine/threonine kinase receptors to the nucleus. Transforming growth factor (TGF)-beta stimulation leads to phosphorylation and activation of Smad2 and Smad3, which form complexes with Smad4 that accumulate in the nucleus and regulate transcription of target genes. Smad2 and Smad3 share highly homology. SMAD2/3 signal transduction appeared to be important in the regulation of muscle-specific genes. SMAD proteins transmit signals from transmembrane serine/threonine kinase receptors to the nucleus. Smad2 is a 58 kDa member of a family of proteins involved in cell proliferation, differentiation and development. Smad3 is a 50 kDa member of a family of proteins that act as key mediators of TGF beta superfamily signaling in cell proliferation, differentiation and development.
