Calcium-dependent cysteine proteinases, or calpains, are widely distributed in mammalian cells. There are 2 distinct molecular forms, calpains 1 and 2, which differ in the quantity of calcium required.Both calpains 1 and 2 are heterodimeric; each is composed of 1 heavy (about 80 kD), CAPN1 and CAPN2, respectively, and 1 shared light (about 30 kD) subunit, CAPNS1. The heavy subunit has a catalytic function, and the light subunit is regulatory (1).

Immunocytochemistry: 1:100-1:250
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
