Used in immunology and biomedical research to quantitatively measure levels of CCL5 (also known as RANTES) in biological samples such as serum, plasma, cell culture supernatants, and tissue extracts. The kit helps investigate inflammatory responses, immune cell recruitment, and disease mechanisms in conditions like HIV, asthma, rheumatoid arthritis, and cancer. It is widely applied in drug development and clinical studies to monitor chemokine expression and evaluate therapeutic efficacy. The assay provides high sensitivity and specificity, enabling accurate detection of CCL5 concentration changes in experimental models and patient samples.
