Trimethoprim ELISA Test Kit for seafood

  • Sep 01, 2026   Anon

Trimethoprim ELISA Test Kit

Catalog No. LSY-10065

1. Principle

This test kit is based on the indirect competitive enzyme immunoassay for the detection of Trimethoprim in the sample. The coupling antigens are pre-coated on the micro-well stripes. The Trimethoprim in the sample and the coupling antigens pre-coated on the micro-well stripes compete for the anti-Trimethoprim antibody. 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 Trimethoprim in it. This value is compared to the standard curve and the Trimethoprim concentration is subsequently obtained.
