Anti-CD274 Antibody

A high-purity polyclonal reagent from the Antibodies.com catalogue, this primary antibody specifically targets CD274—widely recognized as PD-L1 or B7-H1—and is raised in a Rabbit host. Supplied as a 50 µl liquid volume at a working concentration of 1 mg/ml, the product is completely unconjugated, offering researchers flexibility for custom downstream applications. It is validated for Western Blot (WB) assays and demonstrates reliable cross-reactivity across Human, Mouse, and Rat biological samples. With an estimated protein purity of greater than 95%, the reagent ensures highly specific binding for the accurate detection of endogenous CD274 levels in lysates. The formulation consists of Phosphate buffered saline (PBS) supplemented with 0.05% sodium azide, buffered to an approximate pH of 7.3 to maximize shelf-stability. Intended strictly for research use only, this antibody provides a dependable tool for immune checkpoint and co-stimulatory signaling studies. Standard storage guidelines recommend aliquoting upon arrival and maintaining the product at -20°C, while strictly avoiding repeated freeze-thaw cycles to preserve its functional integrity.
