FSTest Olaquindox Metabolite (MQCA) ELISA Test Kit – High-Sensitivity Detection for Banned Growth Promoter Monitoring

Introduction:

The FSTest Olaquindox Metabolite ELISA Test Kit is a highly specific immunoassay designed for quantitative detection of 3-methylquinoxaline-2-carboxylic acid (MQCA), the marker residue of banned growth promoter olaquindox, in animal tissues and seafood.     With a 0.5ppb detection limit, this kit provides reliable monitoring to comply with global food safety regulations.

Key Features & Benefits:

✔ Ultra-Sensitive Detection - 0.5ppb limit of detection for precise MQCA quantification

✔ Exceptional Specificity - 100% cross-reactivity with MQCA,<1% with olaquindox/carbadox

✔ Regulatory Compliance - Meets requirements for monitoring banned quinoxaline drugs

✔ High-Throughput Format - 96-well design for efficient batch processing

✔ Validated Performance - ≤10% CV ensures reproducible results

✔ Streamlined Workflow - Optimized extraction protocol for meat and seafood

Applications:

Monitoring banned olaquindox residues in pork, poultry

Seafood safety testing (fish, shrimp)

Food import/export compliance verification

Veterinary drug residue surveillance programs

Testing Principle:

This competitive ELISA measures absorbance at 450nm (inversely proportional to MQCA concentration) against a standard curve (0-16.2ppb range).

How to Use:

1️⃣ Sample Preparation:

Homogenize tissue/seafood samples

Extract with ethyl acetate/HCl

Evaporate and reconstitute

2️⃣ Test Procedure:

Add 50μL sample/standard to wells

Add 50μL enzyme conjugate & antibody

Incubate 30min at 20-28°C

Wash 4-5 times

Add substrate, incubate 30min

Add stop solution

Measure absorbance at 450nm using a microplate reader.

3️⃣ Result Interpretation:

Compare to standard curve (0.3-16.2ppb)

Multiply by 1.5× dilution factor
