Human Staphylococcus aureus enterotoxin
2. Matters needing attention
This reagent is an in vitro test reagent. It should be used within the validity period. The reagent should be regarded as an infectious agent. Reagents with different batch numbers should not be mixed.
Before use, the reagents in the box should be taken out and left at room temperature for at least 30 minutes.
Store at 2-8 ° C, do not freeze, please see the label in the box for the expiration date.
After the concentrated washing liquid crystallizes, please incubate at 37 ℃ for 15 minutes
3. Operation steps
Add 100ul of diluted sample serum and standard for each well.
The plate was incubated at 37 ° C for 30 minutes.
Shake off the liquid in the plate, wash with the application washing liquid, stay for 30 seconds each time, pat dry on the paper. Repeat the operation 5 times.
Add 100ul of enzyme-labeled coupling solution to each well.
The plate was incubated at 37 ° C for 30 minutes.
Shake off the liquid in the plate, wash with the application washing liquid, stay for 30 seconds each time, pat dry on the paper. Repeat the operation 5 times.
Add 50 ul each of Substrate A and Substrate B to each well, and place in a 37 ° C incubator for 15 minutes.
8. Add 50ul of stop solution to each well and read the OD value at 450nm wavelength.
Human Staphylococcus aureus enterotoxin
