Oxytetracycline is a kind of 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. Oxytetracycline have seen an emergence in the aquaculture industry due to their effectiveness against gram-negative and gram-positive organisms.

The Oxytetracycline ELISA Kit produced by Meizheng significantly reduces both the testing cost and the operating difficulties.

Use Principles:

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

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.
