The L-Asparagine/L-Glutamine/Ammonia test kit is a novel method for the specific, convenient, cost effective and rapid measurement and analysis of L-asparagine, L-glutamine and ammonia as acrylamide precursors in the food industry, or as cell culture media/supernatant components, or in other materials.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).

Attogene’s PCR kit for Microcystin is designed for the In vitro analysis of the MycE gene region responsible for assembling part of the Microcystis peptide. The MycE gene region specific primer and probe mix is provided to be detected through the FAM channel on a qPCR machine. A sample of algae is obtained and washed to extract a clean algal gDNA sample. A reaction mixture is assembled from primers, probe, master mix, and gDNA samples as required. The qPCR machine of choice is set up and loaded as needed and the mixture undergoes PCR amplification. The Primer mix provided exploits the Taq polymerase to amplify the gene region of interest; while the DNA probe mixture is cleaved during amplification to release its FAM fluorophore. The resulting FAM release can be detected on a variety of qPCR platforms.

The Protein Digestibility Assay Kit (K-PDCAAS) is used for in vitro measurement of the Animal-Safe Accurate Protein Quality Score (ASAP-Quality Score Method) developed under patent by Medallion Labs. This digestibility score, in conjunction with the essential amino acid profile plus protein and moisture content of the sample, is used to calculate the Protein Digestibility Corrected Amino Acid Score (PDCAAS) value.
