Concentration	lot specific
Purification	Standard chromatographic techniques.
Conjugation	Agarose
Storage Condition	Store the antibody at -20°C. Avoid repeated freezing and thawing.
Background	The calpains are calcium-dependent cysteine proteases that are widely expressed in mammalian systems. Both m-calpain (calpain II) and -calpain (calpain I) are composed of an 80 kD subunit and a 30 kD subunit. Whereas the 30 kDa subunit is shared by both enzymes, the larger catalytic subunits are different and exhibit the distinct Ca ++ requirements that are suggested by their names. Whereas m-calpain requires millimolar (mM) levels of calcium, u-calpain is active at micromolar (uM) concentrations of Ca++. In addition to the ubiquitously expressed m- and u-calpains, some tissue-specific calpains have been identified. The calpains appear to serve multiple physiological roles, and ideas concerning the functions of these enzymes are in a state of rapid flux.
Synonyms	CAPN2, CANPL2, CANP-2, CAPN1, CANPL1, CANP1
