Calpain-1 catalytic subunit (UniProt: P07384; also known as EC:3.4.22.52, Calcium-activated neutral proteinase 1, CANP 1, Calpain mu-type, Calpain-1 large subunit, Cell proliferation-inducing gene 30 protein, Micromolar-calpain, muCANP) is encoded by the CAPN1 (also known as CANPL1, PIG30) gene (Gene ID: 823) in human. Calpains belong to a family of non-lysosomal, calcium-dependent thiol proteases that proteolyze a wide variety of cytoskeletal, membrane-associated, and regulatory proteins. It is a cytosolic enzyme that translocates to the plasma membrane upon Ca2+ binding. Typical calpains are characterized by a C-terminal Ca2+-binding domain that includes EF-hand motifs, while atypical calpains lack this region, but often contain additional domains. Calpains respond to calcium signals by cleaving specific proteins that are frequently components of signaling cascades, thereby irreversibly modifying their function. Two major isoforms of calpain are reported in mammals, calpain-1 and calpain-2 that are constitutively expressed in all tissues and differ in their calcium requirement for activation (~50 M for calpain-1 and ~500 M for calpain-2). They are composed of non-covalently linked 80 kDa subunit that contains the catalytic subunit (aa 55-354) and a 30 kDa subunit with a regulatory subunit. The 80 kDa subunit consists of four domains (I - IV) and the 30 kDa unit has 2 domains (V and VI). Domain I is partially removed during autolysis. Domain II is the protease domain, which is structurally similar to the catalytic domain of other cysteine proteases. It contains a Cys, His, Asn triad characteristic of cysteine proteases. Domain III exhibits homology with typical calmodulin binding proteins and interacts with calcium binding domains (IV and VI) freeing domain II for protease activity. Domain IV is a Ca2+-binding domain structurally similar to calmodulin. Domain V contains a hydrophobic region and is essential for calpain interaction with membranes. Domain VI has five EF-hands. There are two EF-hand pairs, one pair (EF1-EF2) displays an open conformation and the other (EF3-EF4) displays a closed conformation. The fifth EF-hand (EF5) has closed conformation. Over-expression of calpains has been positively linked to both acute and chronic neurodegenerative processes including ischemia, trauma, and Alzheimer s disease. In Alzheimer s disease the ratio of active to inactive calpain-1 is reported to be much higher. Calpain proteolysis is usually the late-stage common pathway towards cell death induced by excitotoxic compounds. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

30 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
