Animal and Aquatic Tissue Sulfonamides ELISA Test Kit

Qualitative or quantitative analysis of sulfonamides residues in tissue, aquatic tissue, etc.


Sulfonamides are group of synthetic antibiotic agents that have been widely used for therapeutic and prophylactic purposes in both animals and human. They are used as feed additives as well, mainly for fattening of calves and pigs. SAs have seen an emergence in the aquaculture industry due to their effectiveness against gram-negative and gram-positive organisms.

HPLC/GC-MS method is now widely used in the detection of sulfonamides residues, but its high cost and complex operation make it unacceptable.

Use Principles

Sulfonamides ELISA Kit is an indirect competitive enzyme-labeled immunoassay. The sulfonamides antigen is precoated on the wells. The precoated antigen compete the sulfonamides antibody (antibody solution) with sulfonamides in the sample, anti- sulfonamides antibody binds to the sulfonamides-HRP enzyme conjugate. Then pipet 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 sulfonamides concentration of the samples is derived.


Sulfadiazine 100%

Sulfadoxine 181%

Sulfamonomethoxine 150%

Phthalylsulfathiazole (PST) 90%

Sulfamethoxydiazine 85%

Sulfadimethoxypyrimidine 67%

Benzene Sulfapyridine 62%

Sulfapyridine 55%

Sulfamerazine 52%

Sulfamethizole 49%

Sulfachloropyridazine 29.6%

Sulfamethazine 13%

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.
