 Green Spring Ractopamine ELISA Test Kit

Catalog No. LSY-10013


Product Description



1. Principle

The test kit is based on the competitive enzyme immunoassay for the detection of Ractopamine

in the sample. The conjugated antigens is pre-coated on the micro-well stripes. The Ractopamine

 in the sample and the coupling antigens pre-coated on the micro-well stripes compete for

anti-Ractopamine antibodies. After the addition of the enzyme conjugate, the TMB substrate

is added for coloration. The optical density (OD) value of the sample has a negative

correlation with the Ractopamine concentration in the sample. The value is compared to

the standard curve and the Ractopamine concentration is subsequently obtained.
