Milk Qualitative or Quantitative Gentamicin ELISA Test Kit

Qualitative or quantitative analysis of gentamicin residues in raw milk.

Order No.: SC0046


Gentamicin (GEN) belongs to aminoglycoside antibiotics, mainly acting on Gram-negative bacteria. It is widely used in veterinary clinics and animal feed additives due to its broad antibacterial spectrum, good efficacy, and low price. However, the serum effective concentration of GEN is very similar to the toxic concentration, and the safety range is small. It is easy to produce toxic and side effects during its application. Especially, the use of large doses is not standardized, which may easily lead to excessive GEN residues in animal food and pose a hazard to human health. Severe damage to cranial nerves, hearing and kidneys.


Gentamicin ELISA Test Kit is an indirect competitive enzyme-labeled immunoassay. The gentamicin antigen is precoated on the wells. The precoated antigen compete the gentamicin antibody (antibody solution) with sulfonamides in the sample, anti-gentamicin antibody binds to the gentamicin-HRP enzyme conjugate. Then pipette the substrate solutions to the wells to convert the color.

The color of unknown samples is compared to the color of the standards and the gentamicin concentration of the samples is derived.

Aflatoxin M1 Immunoaffinity Column

Order No.: QC0068,QC0069,QC0131,QC0071Column Capacity:100 ngVolumn: 3mLPackage: 25/50T 

Immunoaffinity Column for Aflatoxin B1,B2,G1,G2

The immunoaffinity column can selectively adsorb aflatoxins (B1, B2, G1, G2) from the sample solution, thereby purifying the sample. The purified sample solution can then be directly used for HPLC or LC-MS/MS analysis.Affinity columns can be used in combination with HPLC or LC-MS/MS to achieve rapid testing, and to increase signal-noise ratio  and improve the accuracy of the detection method.

Immunoaffinity Column for 2-in-1 Aflatoxins (B1,B2,G1,G2) and Ochratoxin A

The immunoaffinity column can selectively adsorb aflatoxin (B1, B2, G1, G2) and Ochratoxin A from the sample solution, thereby having a highly targeted purification effect on the sample. The sample  solution that has been purified by passing through the affinity column can be directly used for HPLC analysis or for LC-MS/MS analysis after concentrating with nitrogen gas and resuspended.Order No.: HCM3725B/HCM3750BProduct Properties: AFT B1/B2/G1/G2 300ng, OTA 100ngSpecifications: 3mL,25T/50T
