Used in immunological research to quantify CCL5 levels in biological samples such as serum, plasma, and cell culture supernatants. Helps in studying inflammatory responses, immune cell recruitment, and disease mechanisms including autoimmune disorders, viral infections like HIV, and cancer progression. Commonly applied in preclinical studies to evaluate therapeutic interventions targeting chemokine pathways. Provides a reliable, sensitive, and specific method for detecting rat CCL5, enabling researchers to monitor changes in chemokine expression under experimental conditions.
