Used in biomedical research to quantify levels of human Integrin α2β1 in cell lysates, serum, plasma, and other biological samples. Enables study of integrin expression in cell adhesion, migration, and signaling processes. Commonly applied in research on thrombosis, cancer metastasis, immune responses, and extracellular matrix interactions. Supports investigation of therapeutic targets and disease mechanisms involving α2β1 integrin receptor activity.
