Purity: > 95% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 1mM DTT, 10% glycerol . Neuronal calcium sensor 1, also known as NCS1, is a member of the neuronal calcium sensor gene family, which encode calcium-binding proteins expressed predominantly in neurons. NCS1 is localized to neuronal cell bodies and axons throughout the brain and spinal cord. It is also expressed in glial cells and in neuroendocrine bovine adrenal chromaffin and PC12 cells. NCS1 is a regulatory protein involved in Ca++-dependent exocytosis of synaptic vesicles and dense core granules. Recombinant human NCS1 fused to His-tag at C-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
