ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Target description

Perforin-1 (UniProt: P14222; also known as P1, Cytolysin, Lymphocyte pore-forming protein, PFP) is encoded by the PRF1 (also known as PFP) gene (Gene ID: 5551) in human. Perforin-1 is a multi-pass membrane glycoprotein that is synthesized with a signal peptide (aa 1-25), which is subsequently cleaved off to produce the mature form that contains two transmembrane domains (aa 129-149 and 257-279). It is stored in cytolytic granules of cytolytic T-lymphocytes and is secreted into the cleft between T-lymphocyte and target cell. Perforin has a thin key-shaped structure consisting of an N-terminal membrane attack complex perforin-like (MACPF)/cholesterol dependent cytolysin (CDC) domain (aa 27-375), which is followed by an EGF domain (aa 376-408) that together with the extreme C-terminal sequence forms a central shelf-like structure. Its C-terminal C2 domain (aa 397-519) mediates initial, Ca2+-dependent membrane binding. Perforin-1 serves as a pore-forming protein that plays a key role in granzyme-mediated programmed cell death, and in defense against virus-infected or neoplastic cells. It also plays an important role in killing other cells that are recognized as non-self by the immune system. It can insert into the membrane of target cells in its calcium-bound form and can oligomerize and form large pores. Its membrane insertion and pore formation require a major conformation change. It promotes cytolysis and apoptosis of target cells by facilitating the uptake of cytotoxic granzymes. Mutations in PRF1 gene have been linked to familial Hemophagocytic lymphohistiocytosis (FHL2), a rare disorder that is characterized by immune dysregulation with hypercytokinemia, defective function of natural killer cell, and massive infiltration of several organs by activated lymphocytes and macrophages. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 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.

Reconstitution

300 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.

Storage and Stability

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.
