Used in immunological research to quantify levels of human β2 integrin (CD11/CD18) in biological samples such as blood, plasma, or cell lysates. This ELISA kit enables researchers to study the role of β2 integrins in immune cell adhesion, migration, and activation, particularly in conditions involving inflammation, autoimmune diseases, and leukocyte deficiencies. It is a valuable tool for investigating immune responses, monitoring disease progression, and evaluating therapeutic interventions targeting integrin-mediated pathways.
