Used in biomedical research to quantify levels of the ARPC1B protein in cell lysates or tissue samples. Helps investigate actin cytoskeleton dynamics, particularly in studies related to cell motility, immune cell function, and intracellular signaling. Widely applied in research on hematological disorders and immunodeficiencies linked to ARPC1B deficiencies. Enables high-throughput screening in drug development and mechanistic studies of cytoskeletal regulation.
