Purity: > 95% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH8.0) containing 1mM DTT, 10% glycerol, 2mM EDTA . Calbindin 1 is a calcium binding protein belonging to the troponin C superfamily. Calbindin is expressed in neural tissues. It plays an essential role in calcium regulation (including calcium transport and uptake, calcification of bone and teeth) and calcium related signalling in neurons and transiently in embryological development. This calbindin also has a role in protecting neurons from apoptotic cell death. Disregulation of this calbindin protein relates to epilepsy, amyotrophic lateral sclerosis, Huntington's disease. Recombinant human Calbindin1 was expressed in E.coli and purified by using conventional chromatography techniques.
