Preparation Note

Prepared from blood that has been shown by certified tests to be negative for HBsAg and for antibodies to HIV and HCV.

Reconstitution

Following initial thaw, aliquot and freeze (-70°C).

Analysis Note

Comparable to reference lot by SDS-PAGE

Cell calcium, 46(4), 257-262 (2009-09-08)
Neuronal calcium sensor-1 (NCS-1) is a high-affinity, low-capacity Ca(2+)-binding protein expressed in many cell types. We previously showed that NCS-1 interacts with inositol 1,4,5-trisphosphate receptor (InsP(3)R) and modulates Ca(2+)-signaling by enhancing InsP3-dependent InsP(3)R channel activity and intracellular Ca(2+) transients. Recently

Calcium ion movements between cellular stores and the cytosol govern muscle contraction, the most energy-consuming function in mammals, which confers skeletal myofibers a pivotal role in glycemia regulation.

Identification of mechanisms promoting neutrophil trafficking to the lungs of patients with cystic fibrosis (CF) is a challenge for next generation therapeutics. Cholesterol, a structural component of neutrophil plasma membranes influences cell adhesion, a key step in transmigration. The effect

The inhibitory domains of calpastatin contain three highly conserved regions, A, B, and C, of which A and C bind calpain in a strictly Ca(2+)-dependent manner but have no inhibitory activity whereas region B inhibits calpain on its own. We

Autophagy and apoptosis, which could be induced by common stimuli, play crucial roles in development and disease. The functional relationship between autophagy and apoptosis is complex, due to the dual effects of autophagy. In the Bombyx Bm-12 cells, 20-hydroxyecdysone (20E)
