Used in immunological research to quantify Intercellular Adhesion Molecule 3 (ICAM-3/CD50) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables the study of immune cell interactions, particularly in early immune responses where ICAM-3 plays a role in leukocyte adhesion and activation. It is widely applied in research related to inflammation, autoimmune diseases, and immune system regulation. The assay supports the detection of soluble ICAM-3, aiding in biomarker discovery and evaluation of therapeutic interventions targeting cell adhesion pathways.
