Total Aflatoxin ELISA Test Kit
Product Description
REAGEN™Total Aflatoxin ELISA Test Kit is a competitive enzyme immunoassay
for the quantitative analysis of Total Aflatoxin in cereals,
meat/fish, feed, milk ,oils,peanuts and pistachios.
The unique features of the kit are:
1. High recovery (80-105%),rapid(10-40minutes), cost-effective
extraction methods.
2. High sensitivity (0.05ng/g or ppb).
3. High reproducibility.
4. A quick ELISA assay (less than 2 hours regardless of number of
samples).
Procedure Overview
The method is based on a competitive colorimetric ELISA assay. The
toxin of interest has been coated in the plate wells. During the
analysis, sample is added along with the primary antibody specific
for the target toxin. If the target is present in the sample, it
will compete for the antibody, thereby preventing the antibody from
binding to the toxin attached to the well. The second antibody,
tagged with a peroxidase enzyme, targets the primary antibody that
is complexed to the toxin coated on the plate wells. The resulting
color intensity, after addition of substrate, has an inverse
relationship with the target concentration in the sample.

Warnings and Precautions
§ The standards contain Total Aflatoxin . Handle with particular
care.
§ Do not use the kit past the expiration date.
§ Do not intermix reagents from different kits or lots except for
components with the same part No’s within their expiration dates.
§ Try to maintain a laboratory temperature of 20°–25°C (68°–77°F).
Avoid running assays under or near air vents, as this may cause
excessive cooling, heating and/or evaporation. Also, do not run
assays in direct sunlight, as this may cause excessive heat and
evaporation. Cold bench tops should be avoided by placing several
layers of paper towel or some other insulation material under the
assay plates during incubation.
§ Make sure you are using only distilled or deionized water since
water quality is very important.
§ When pipetting samples or reagents into an empty microtiter
plate, place the pipette tips in the lower corner of the well,
making contact with the plastic.
§ Incubations of assay plates should be timed as precisely as
possible. Be consistent when adding standards to the assay plate.
Add your standards first and then your samples.
§ Add standards to plate only in the order from low concentration
to high concentration as this will minimize the risk of
compromising the standard curve.
§ Always refrigerate plates in sealed bags with a desiccant to
maintain stability. Prevent condensation from forming on plates by
allowing them equilibrate to room temperature (20 – 25°C / 68 –
77°F) while in the packaging.
