Anti-RASA4 Antibody

The RASA4 protein (RAS p21 protein activator 4), also referred to as CAPRI, is a Ras GTPase-activating protein that modulates Ras/MAPK signaling by accelerating GTP hydrolysis on Ras family small GTPases. This rabbit polyclonal antibody from Antibodies.com is raised against RASA4 and validated for Western blot detection across human, mouse, and rat sample lysates.

Each vial contains 100 µl of unconjugated polyclonal antibody at 1 mg/ml, formulated in phosphate buffered saline (PBS) with 0.05% sodium azide at approximately pH 7.2. The polyclonal composition recognizes multiple epitopes on the target, supporting robust signal generation in Western blot workflows that include SDS-PAGE separation and standard membrane transfer protocols.

For handling, aliquot the antibody upon receipt and store at -20°C to preserve activity across freeze-thaw cycles; working aliquots can be refrigerated for short-term use. The unconjugated format leaves conjugation open to the end user, allowing direct labeling with a chosen fluorophore, HRP enzyme, or bead-based detection reagent for downstream applications.
