MQCA (3-methyl quinoxaline-2-carboxylic acid) ELISA Kit

This Assay Genie competitive ELISA targets MQCA, the principal marker residue of olaquindox, a quinoxaline-type antimicrobial historically administered as a livestock growth-promoting feed additive in swine and poultry production. Because olaquindox has been restricted or withdrawn from feed-additive use in the European Union, China, and other jurisdictions, MQCA concentrations in edible tissues are routinely monitored to verify compliance with veterinary drug residue limits and withdrawal periods.

The assay is calibrated for the muscle and liver matrices specified, supporting routine residue surveillance, confirmatory testing of non-compliant samples, and quality control workflows in food-safety and veterinary laboratories. Each package supplies reagents for one microplate run, with separate aliquots reserved for standards, samples, conjugate, and substrate preparation. Smaller sample volumes can be accommodated when working with limited biopsy or archive material.

Intended for in vitro research use only; store refrigerated between uses and protect the substrate solution from light to preserve reagent performance across the kit shelf life.
