Sudan red ELISA Test Kit,specification,price,image-Bio-Equip in China

1. Principle

Sudan red ELISA kit is a competitive enzyme immunoassay for the quantitative analysis of

Sudan red in milk, honey and meat.The coupling antigens are coated on the micro-well

stripes.

The Sudan red in the sample and the coupling antigens coated on the microwell stripes

compete for the anti-Sudan red 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 Sudan red in it.

The measurement is made photometrically at 450 nm. The absorption is inversely proportional to

the Sudan red concentration in the sample.
