Anti-CD274 Antibody

Sourced from Antibodies.com and distributed through the Bio-Connect catalogue, this affinity-purified polyclonal reagent is raised in rabbit and specifically targets human CD274 (also known as PD-L1 or B7-H1). The unconjugated antibody is supplied as a 50 µl vial at a concentration of 1 mg/ml, formulated in phosphate-buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2, and is recommended for use in Western blot (WB) and immunohistochemistry (IHC) workflows. Validated for reactivity with human samples, the polyclonal antiserum has an estimated purity of greater than 95% following affinity purification against the immunogen and is intended for research use only. For optimal preservation of activity, the reagent should be stored at -20 °C, protected from light, and protected against repeated freeze-thaw cycles. This Antibodies.com reagent offers a reliable, well-characterized tool for detecting endogenous levels of total CD274 protein in cell lysates and tissue sections, supporting studies in immunology, oncology, and immune-checkpoint research where PD-L1 expression is of interest.
