Description de la cible

CD9 antigen (UniProt: P21926; also known as 5H9 antigen; Cell growth-inhibiting gene 2 protein; Leukocyte antigen MIC3; Motility-related protein; MRP-1; Tetraspanin-29; Tspan-29; p24) is encoded by the CD9 (also known as MIC3, TSPAN29; IG2) gene (Gene ID: 928) in human.  CD9 is a multi-pass membrane protein of the tetraspanin (TM4SF) family with three cytoplasmic domains, four transmembrane domains, and two extracellular domains. It forms both disulfide-linked homodimers and higher homooligomers and heterooligomers with other members of the tetraspanin family. It is expressed in a variety of hematopoietic and epithelial cells and displays strong expression in platelets where it mediates platelet activation and aggregation upon binding to monoclonal antibodies. In unstimulated platelets, it is palmitoylated at a low, basal level, which increases when platelets are activated by thrombin. In macrophages, it is shown to associate with CD81 and β1 and β2 integrins and prevent macrophage fusion into multinucleated giant cells that are specialized in ingesting complement-opsonized large particles.  At the cell surface of oocytes, it plays a KEY^® role in sperm-egg fusion, possibly by organizing multiprotein complexes and the morphology of the membrane required for the fusion. CD9 is also involved in cell adhesion, cell motility, and tumor metastasis and its down-regulation correlates with reduced cancer cell growth. It can hamper metastasis formation by inhibiting integrin-mediated motility. Lower expression of CD9 is associated with weaker matrix adhesion and diffuse tumor cell growth in vitro. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity^™, reproducibility, and stability over conventional monoclonals.

Forme physique

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.

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.

Stockage et stabilité

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.
