The unique features of the kit are: Rapid and simple method Minimal sample prep High accurate and reproducible Procedure Overview REAGEN™ Urea Enzymatic Assay Kit measures the concentration of urea using the urease enzyme, which converts urea to ammonia. urease CO(NH2)2 + H2O CO2 + 2 NH3 The ammonia produced from the urea is then directly detected by a colorimetric chemical reaction.

REAGEN - Fumonisin Toxin ELISA Test Kit

REAGEN™Fumonisin ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of Fumonisin in cereals, dried meat/fish, feed, milk and seed . The unique features of the kit are: High recovery (80-105%),rapid(10-20minutes), cost-effective extraction methods. High sensitivity (1 ng/g or ppb). High reproducibility. A quick ELISA assay (less than 1 hours regardless of number of samples). Procedure Overview The method is based on a competitive colorimetric ELISA assay. The toxin of interest has been coated in the plate wells. During the analysis, sample is added along with the primary antibody specific for the target toxin and enzyme-conjugate. If the target is present in the sample, it will compete for the antibody, thereby preventing the antibody from binding to the toxin attached to the well. The enzyme-conjugate, will bined with the primary antibody that is complexed to the toxin coated on the plate wells. The resulting color intensity, after addition of substrat

REAGEN - Total Aflatoxin ELISA Test Kit

REAGEN™Total Aflatoxin ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of Total Aflatoxin in cereals, meat/fish, feed, milk ,oils,peanuts and pistachios . The unique features of the kit are: High recovery (80-105%),rapid(10-40minutes), cost-effective extraction methods. High sensitivity (0.05 ng/g or ppb). High reproducibility. A quick ELISA assay (less than 2 hours regardless of number of samples). Procedure Overview The method is based on a competitive colorimetric ELISA assay. The toxin of interest has been coated in the plate wells. During the analysis, sample is added along with the primary antibody specific for the target toxin. If the target is present in the sample, it will compete for the antibody, thereby preventing the antibody from binding to the toxin attached to the well. The second antibody, tagged with a peroxidase enzyme, targets the primary antibody that is complexed to the toxin coated on the plate wells. The resulting color intensity

REAGEN - Total Antibiotics in Milk Test Kit

REAGEN™Total Antibiotics in Milk Test Kit provides an easy and simple test method for detecting total antibiotics in milk. Compared with current commercially available kits,. the unique features of the kit are: A quick spore growth assay (results can be read in about 3 hours). Detection of wide range of antibiotics in milk. High reproducibility. High sensitivity and low detection limit. Procedure Overview The method is based on the inhibition of a standard microbial growth recommended by international organizations. The kit is presented in a microplate format where each well contains medium agar spread with bacillus spores. When the plate (or a strip of wells) is incubated at 65C, these bacillus spores germinate and the bacillus grows so that acids are produced, which result in the pH value changes. The color of the pH indicator in the medium changes from purple to yellow. If milk samples contain antibiotics at higher concentration than the detection limit, the bacillus will not g

REAGEN - Streptomycin ELISA Test Kit

REAGEN™ Streptomycin ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of streptomycin and dihydrostreptomycin in feed, honey, kidney, liver, meat (beef, chicken and pork), milk, serum and urine.
