Melamine ELISA Test Kit For Milk
- Sep 03, 2026 Anon
Melamine ELISA Test Kit
Catalog No. LSY-10026
1. Principle
This test kit is based on the indirect competitive enzyme immunoassay for the detection of Melamine in the sample. The coupling antigen is pre-coated on the micro-well stripes. The Melamine in the sample and the coupling antigens pre-coated on the micro-well stripes compete for anti-Melamine antibodies. 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 Melamine concentration in the sample. This value is compared to the standard curve and the Melamine concentration is subsequently obtained.
