  1. Enterotoxin (SE) is a pathogenic substance that causes Staphylococcus aureus food poisoning. According to its antigenicity, it can be divided into 8 serotypes A-E and G-I, of which SEA is the most common. Enterotoxins in food are not easily inactivated during processing and can cause symptoms such as vomiting and diarrhea. In severe cases, they can cause multiple organ dysfunction and be life-threatening.
  2. This kit is a new generation of Staphylococcus aureus total enterotoxin (SET) detection product using ELISA , which can minimize operating errors and work intensity.


This kit adopts double antibody sandwich ELISA method. Pre-coat the total amount of Staphylococcus aureus enterotoxin antibody on the microplate. Both the total amount of pre-coated enterotoxin antibody and detection antibody bind to the enterotoxin in the sample at the same time. And then the complex combines with the HRP-conjugate to form an antibody- enterotoxin- antibody- enzyme- HRP-conjugate, which can be colored by TMB substrate. The absorbance of the sample is positively correlated with the content of Staphylococcus aureus enterotoxin.

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

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.
