Used in biomedical research to detect and quantify integrin VLA-4 (Very Late Antigen-4) levels in cell or tissue samples. This kit is particularly valuable in studies related to inflammation, autoimmune diseases such as multiple sclerosis, and cancer metastasis, as VLA-4 plays a key role in leukocyte adhesion and cell migration. The ELISA format allows for high-sensitivity measurement, supporting drug development and mechanistic studies targeting integrin-mediated pathways.
