This SMAD4 antibodyis to be used only for research purposes and not for diagnostics..
A portion of amino acids 255-284 from the human protein was used as the immunogen for this SMAD4 antibody.
Titration of the SMAD4 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.
Aliquot the SMAD4 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.
SMAD4 is the common SMAD (co-SMAD)mediator of signal transduction by TGF-beta (transforming growth factor). It promotes binding of the SMAD2/SMAD4/FAST-1 complex to DNA and provides an activation function required for SMAD1 or SMAD2 to stimulate transcription. It may act as a tumor suppressor.
