Anti-CD81 Antibody

Rabbit polyclonal antibody targeting CD81 (TAPA-1), a ubiquitously expressed tetraspanin membrane protein involved in immune cell signaling, vesicle trafficking, and cell-cell adhesion. This unconjugated primary antibody from Antibodies.com is raised in rabbit and validated for Western blot and ELISA workflows across human, mouse, and rat samples. Supplied as a 100 µL liquid aliquot, the reagent enables detection of endogenous CD81 in lysates from lymphoid and non-lymphoid tissues, as well as characterization of exosomal markers in cell culture supernatants. For research use only, the antibody is intended for studies of B-cell receptor complex assembly, hepatitis C virus entry co-receptor function, and tetraspanin-enriched microdomain biology. Aliquot upon arrival and store at -20°C, avoiding repeated freeze-thaw cycles to preserve reagent performance.
