Used in biomedical research to measure levels of vascular endothelial cell adhesion molecule 1 (VCAM-1) in rat samples. Helps assess endothelial activation and inflammation in studies related to cardiovascular diseases, atherosclerosis, and immune responses. Commonly applied in preclinical research to evaluate the effects of drugs or experimental treatments on vascular inflammation. Provides a quantitative and sensitive method to detect VCAM-1 in cell culture supernatants, serum, or tissue extracts.
