Product Description

MA3-913 detects calsequestrin from human, mouse, rat, canine, porcine, chicken, and rabbit skeletal muscle tissues. This antibody recognizes calsequestrin in both type I (slow) and type II (fast) skeletal muscle tissues. MA3-913 has been successfully used in Western blot procedures. By Western blot, this antibody detects a 63 kDa protein representing calsequestrin from canine skeletal muscle extracts. Higher molecular weight proteins are seen on the Western blot and are believed to be calsequestrin-like proteins found in the sarcoplasmic reticulum. The staining pattern yields double rows of fluorescent dots corresponding to triad pairs on either side of the Z-line. The MA3-913 antigen is purified rabbit skeletal muscle sarcoplasmic reticulum. The sarcoplasmic reticulum (SR) is, in part, responsible for maintaining the level of intracellular calcium in cardiac and skeletal muscle by storing and releasing calcium. Several intralumenal SR calcium binding proteins have been identified, the most prominent of these is calsequestrin. Calsequstrin is a calcium binding protein known to sequester calcium accumulated in the sarcoplasmic reticulum of muscle cells during relaxation and is found discretely localized to the junctional and corbular (terminal cisternae) SR.
