- Nitrofuran (AMOZ) ELISA Kit
1. Principle
This test kit is based on the competitive enzyme immunoassay for the detection of AMOZ (3-anmino-5-morpholinomethyl) in the tissue (chicken, fish, shrimp). The coupling antigen is pre-coated on the micro-well stripes. The AMOZ in the testing sample competes with the coupling antigen pre-coated on the micro-well stripes for the antibody against AMOZ. After the addition of the enzyme conjugate, the TMB substrate is added for coloration. The optical density (OD) value of the testing sample has a negative correlation with the content of AMOZ in it. This value is compared to the standard curve and the content of the corresponding AMOZ is subsequently obtained.

- Nitrofuran(AHD) ELISA Kit
1. Principle
This test kit is based on the competitive enzyme immunoassay for the detection of Aminohydantion (AHD) in the tissue (chicken, fish shrimp). The coupling antigen is pre-coated on the micro-well stripes. The Aminohydantion (AHD) in the testing sample competes with the coupling antigen pre-coated on the micro-well stripes for the antibody against AHD. After the addition of the enzyme conjugate, the TMB substrate is added for coloration. The optical density (OD) value of the testing sample has a negative correlation with the content of AHD in it. This value is compared to the standard curve and the content of the corresponding AHD is subsequently obtained.

- Nitrofuran(SEM) ELISA Kit
1. Principle
This test kit is based on the competitive enzyme immunoassay for the detection of semicarbazide (SEM) in the tissue(chicken, fish, shrimp), milk, honey, whole egg. The coupling antigen is pre-coated on the micro-well stripes. The SEM in the testing sample competes with the coupling antigen pre-coated on the micro-well stripes for the antibody against SEM. After the addition of the enzyme conjugate, the TMB substrate is added for coloration. The optical density (OD) value of the testing sample is inversely proportional to the SEM in the sample. This value is compared to the standard curve and the content of the corresponding SEM is subsequently obtained.

The coupling antigen is pre-coated on the micro-well stripes. The Sulfonamides residues in the testing sample competes with the coupling antigen pre-coated on the micro-well stripes for the antibody against Sulfonamides. After the addition of the enzyme conjugate, the TMB substrate is added for coloration. The optical density (OD) value of the testing sample ha-s a negative correlation with the content of Sulfonamides residues in the sample.
