This SMAD 1/2/3/5 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 SMAD1/2/3/5 (GPLQWLDKVLTQMGS) was used as the immunogen for this SMAD1/2/3/5 antibody (100% homologous human, mouse and rat).
The stated application concentrations are suggested starting amounts. Titration of the SMAD 1/2/3/5 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 SMAD 1/2/3/5 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.
SMADs are proteins that modulate the activity of transforming growth factor beta ligands. The SMADs, often in complex with other SMADs/CoSMAD, act as transcription factors that regulate the expression of certain genes. Zhu, H et al concluded that targeted ubiquitination of SMADs may serve to control both embryonic development and a wide variety of cellular responses to TGF-beta signals. R-Smads or receptor regulated Smads are a class of proteins that include SMAD1, SMAD2, SMAD3, SMAD5, and SMAD8. In response to signals by the TGF-beta superfamily of ligands these proteins associate with receptor kinases and are phosphorylated at an SSXS motif at their extreme C-terminus. These proteins then typically bind to the common mediator Smad or co-SMAD SMAD4.
