1. Principle
This test kit is based on the competitive enzyme immunoassay for the detection of Paraquat in tea, fruit (apple, orange) and vegetables (spinach, potato, cabbage). The coupling antigens are pre-coated on the micro-well stripes. The Paraquat in the sample and the coupling antigens pre-coated on the micro-well stripes compete for the anti-Paraq 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 Paraquat concentration in the sample. This value is compared to the standard curve and the content of the corresponding Paraquat is subsequently obtained.
