FSTest Streptomycin ELISA Test Kit – High-Sensitivity Antibiotic Residue Detection for Food Safety Compliance

Introduction:

The FSTest Streptomycin ELISA Test Kit is a precise immunoassay designed for quantitative detection of streptomycin residues in animal tissues, seafood, and honey.  With a 3ppb detection limit, this kit helps enforce compliance with strict international MRLs (500ppb in muscle, 200ppb in milk) for this potentially hazardous aminoglycoside antibiotic.

Key Features & Benefits:

✔ Regulatory-Grade Sensitivity - 3ppb detection limit meets global MRL requirements

✔ Broad Sample Compatibility - Validated for meat, seafood, honey, and dairy

✔ High Specificity - 100% for streptomycin, 56.6% for dihydrostreptomycin

✔ Efficient Workflow - 96-well format processes 20+ samples simultaneously

✔ Reliable Performance - ≤10% CV ensures reproducible results

✔ Simplified Protocol - Minimal sample prep (20× dilution factor)

Applications:

Meat and poultry antibiotic monitoring

Seafood and honey safety testing

Dairy product quality control

Import/export compliance verification

Veterinary drug residue surveillance

Testing Principle:

This competitive ELISA measures absorbance at 450nm (inversely proportional to streptomycin concentration) against a 6-point standard curve (0-3.6ppb).

How to Use:

1️⃣ Sample Preparation:

Meat/Seafood: Homogenize, extract with 20mL buffer, centrifuge

Honey: Dilute 1g sample in 5mL buffer, vortex

2️⃣ Test Procedure:

Add 50μL sample/standard

Add 50μL enzyme conjugate & antibody

Incubate 30min (20-28°C)

Wash 4-5 times

Add substrate, incubate 30min

Add stop solution

Read at 450nm

3️⃣ Result Interpretation:

Compare to standard curve (0.15-3.6ppb)

Multiply by 20× dilution factor
