Anti-Calpain-9 Antibody, clone 1J22 ZooMAb^® Rabbit Monoclonal

Calpain-9 (UniProt: O14815; also known as Digestive tract-specific calpain, New calpain 4, nCL-4, Protein CG36) is encoded by the CAPN9 (also known as NCL4) gene (Gene ID: 10753) in human. The mammalian calpains include both ubiquitous and tissue-specific members. Two major ubiquitous calpains, m-calpain and μ-calpain, and two gastrointestinal-tract (GI) specific calpains, calpain-8 and calpain-9 are found in stomach and intestine. Calpains-9 has a typical domain structure that is similar to calpains 1 and 2. It has a regulatory N-terminal domain (domain I), a protease domain (II, consisting of sub-domains IIa and IIb), a C2-like Ca2+/phospholipid-binding domain (III), and a penta-EF-hand (PEF) domain (IV). Its catalytic region is localized in amino acids 43-337. Calpain-9 expression is down-regulated in gastric cancer tissue and in gastric cell lines of differentiated and poorly differentiated types. It is considered as a tumor suppressor and its low expression has been positively associated with late T stage (tumor size), lymph node metastasis, and advanced TNM stage. This ZooMAb^® 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.

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
