0.1ppb 30min Hormone Testing Kit Without Nitrogen Blowing Testos Terone ELISA​ Test Kit

The unique features of the kit are:

1.Rapid (＜30min), high recovery (≥80%), and cost-effective extraction methods .

2.High sensitivity (0.1 ng/g or ppb) and low detection limit (0.2 ng/g or ppb) .

3.A quick ELISA assay (less than 1.5 hours regardless of number of samples).

4.High reproducibility.

Extraction Diluent

Mix 50mL of methanol with 950mL of distilled water, ready for use.

Meat(Fish,Shrimp,Beef,Chicken,Pork)

• Homogenize a reasonable amount of sample with a suitable mixer.
• Weigh out 1g of the homogenize sample into a suitable vial and mix thoroughly with 4mL of Extraction Diluent, vigorously vortex for 2min.
