Immunogold electron-microscopic localisation of calpain I in skeletal muscle of rats

N Yoshimura et al. Cell Tissue Res. 1986.

Abstract

By using a double-affinity-purified first antibody and colloidal gold-conjugated second antibody, it is shown that calpain I (a cysteine proteinase activated by micromolar concentrations of Ca2+) has a predominant intracellular location in the I-band region of the extensor digitorum longus (EDL) muscle of the rat, but is not exclusively associated with the Z-line.
