Used in research settings to detect and quantify lipoprotein X (LP-X) in rat models, particularly in studies related to cholestatic liver disease and bile flow obstruction. The kit enables investigators to assess LP-X levels in serum or plasma, providing insight into lipid metabolism abnormalities associated with liver dysfunction. It is a valuable tool for preclinical studies evaluating liver injury, drug-induced cholestasis, and therapeutic interventions targeting hepatobiliary transport. Due to its specificity and sensitivity, this ELISA kit supports accurate measurement of LP-X, aiding in the understanding of disease mechanisms and progression in rodent models.
