This ELISA kit provides quantitative measurement of albumin (ALB) in bovine serum and plasma, supporting metabolic and nutritional status research in cattle. Because circulating bovine serum albumin typically ranges from 25–45 mg/mL, researchers need clear guidance on dilution strategy to bring samples within assay range — this kit is designed with that workflow in mind.
Detection Range: The 0.78–50 μg/mL range requires substantial dilution of neat bovine serum or plasma (typically 1:1,000 to 1:50,000), which must be optimized per sample type. This range accommodates both normal physiological levels and the marked hypoalbuminemia seen in hepatic insufficiency, parasitic infection, or protein-energy malnutrition in cattle.
Sensitivity: The 0.39 μg/mL sensitivity ensures accurate quantification even at high dilution factors, preserving resolution to distinguish clinically meaningful declines in albumin concentration associated with chronic inflammation or liver fluke burden.
Sample Compatibility: Validation in both serum and plasma allows researchers to align albumin measurement with herd-level metabolic profiling studies, where anticoagulated plasma is often collected alongside samples for other biomarkers like NEFA or BHB.
Assay Efficiency: The 1–5 hour protocol and 50–100 μL sample volume per well support batch processing of large cohort studies typical in transition cow or feedlot nutrition trials.
This kit is particularly suited for investigating negative energy balance in periparturient dairy cows, hepatotoxicity screening, and nutritional intervention studies.
