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).

Advantages
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.
Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.
The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.
Details of the target and priming specificity are included in the individual handbooks above.
Packaged, optimised and ready to use. Expect Better Data.
Exceptional value for money
Rapid detection of all clinically relevant subtypes
Positive copy number standard curve for quantification
Highly specific detection profile
High priming efficiency
Broad dynamic detection range (>6 logs)
Sensitive to < 100 copies of target
Accurate controls to confirm findings

Suspend 45g in 1L of distilled water,stir until completely dissolved and dispense 100 mL into test tubes , heat at 100 °C for 30 min in a waterbath or flowing steam.
The following quality control strains were inoculated and cultured at 30-35℃ for 24h-48h. The results are as follows:
| Quality control strains | Inoculum (CFU) | Growth |
| Escherichia coli ATCC8739 | < 100 | Good growth |
| Pseudomonas aeruginosa ATCC9027 | ||
| Staphylococcus aureus ATCC6538 | > 100 | Inhibited |
