Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha-chain. It is a dimer of alpha (α) and beta (β) chains. β-tubulin is ubiquitously expressed with highest levels in spleen, thymus and immature brain and it has a highly acidic C-terminal region which may bind cations such as calcium. This antibody can be used as a loading control on Western blots.
GenScript β-tubulin Antibody (2G7D4), mAb, Mouse is produced from the hybridoma resulting from fusion of SP2/0-Ag14 myeloma and B-lymphocytes obtained from mouse immunized with purified human recombinant full-length β-tubulin protein.
