1. Principle This kit is based on the specific reaction of antibody-antigen and immunochromatography. β-lactam and tetracyclines antibiotics in the sample compete for the antibody with the antigen coated on the membrane of the test strip. Then after a color reaction, the result can be observed. 2. Applications This kit is used for rapid qualitative analysis of β-lactam and tetracyclines in milk sample.
This product is used for testing β-Lactam antibiotics residue in raw milk, the whole test only needs about 10 minutes, suitable for all kinds of enterprises and Inspection agency.
1. Principle This test kit is based on the competitive enzyme immunoassay for the detection of Gentamicin in the sample. The coupling antigen is pre-coated on the micro-well stripes. The Gentamicin in the sample and pre-coated coupling antigen on the micro-well stripes compete for the anti-Gentamicin 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 Gentamicin in it. The value is compared to the standard curve and the Gentamicin concentration is subsequently obtained. 2.

1. Introduction The FMD-Ab ELISA is developed to detect the O type antibodies of Porcine Foot and Mouth Disease in porcine serum samples and assess the immunity conditions against FMD in the pig farms. 2. Principle The kit is based on an indirect enzymatic immunoassay.The antigen is coated on plates. When a sample serum contains specific antibodies against virus, they will bind to the antigen on plates. Wash the unbound antibodies and other components. Then add a specific peroxidase conjugate(IgG-HRP). After incubation and washing, add the TMB substrate. A colorimetric reaction will appear, measured by a spectrophotometer.
