The Aspartame test kit is a simple and reliable method for the specific measurement and analysis of Aspartame in beverages and foodstuffs.
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).
We have a wide range of other assay kit products.
Advantages
The Aspartame test kit is a simple and reliable method for the specific measurement and analysis of Aspartame in beverages and foodstuffs.
Fig 1. Only three steps will be need for Sample Preparation and only 20 minitutes will be taken for Sample Preparation.
Fig 2. Seven concentration samples of 5fg/μL, 10fg/μL, 20fg/μL, 30fg/μL, 300fg/μL, 3pg/μL, 30pg/μL, 300pg/μL were detected. CV of each concentration was < 30%, Regression coefficient associated with standard solutions was 0.99975, and amplification efficiency was 100.068%.
Fig 3. Four concentration samples of 5fg/μL, 10fg/μL, 20fg/μL, and 30fg/μL were detected, and 10 multiple holes were detected for each concentration. The detection values of 5fg/μL and above were CV ＜30%.
Fig 4. DNA recovery can be determined by including samples spiked with known DNA amounts which are prepared from the corresponding DNA standards. Typically, the range for this value varies from 70% to 130%.

The resDNASEQ E.coli Residual DNA Quantitation kit is designed for the quantification of residual DNA from E. coli, in cell lines which are used for production of biopharmaceutical products. The resDNASEQ E.coli Residual DNA Quantitation kit use TaqManTM quantitative PCR to perform rapid, specifc quantitation of femtogram levels of residual host-cell or plasmid DNA. The kit was developed to meet the sensitivity requirements defined by WHO (10 ng E. coli DNA per therapeutic dose).
With the development of molecular biology, stool, a new non-invasive sample, has been widely used in the research of animal molecular genetics, population ecology, behavioral ecology and some intestinal disease diagnosis. Stool samples includes gut microbial DNA, food residue sample DNA, and alimentary tract exfoliated cell DNA.
The primary problem encountered when using stool sample for molecular biology research is the low content of exfoliated cells in the digestive tract and a certain degree of degradation of genetic material in stool. Another issue in molecular scatology research based on PCR is the presence of a large number of inhibitors in stool that can affect Taq enzyme activity, leading to downstream detection inactivation. These inhibitors include polysaccharides, plant polysaccharides, bile acids, bile salts, bile pigments, digestive juices, mucus, etc. Therefore, selecting appropriate extraction methods to obtain high-quality DNA is the key to successful downstream detection of stool DNA.
At present, the pretreatment methods used in the laboratory, such as phenol/chloroform extraction, cetyltrimethyl bromide (CTAB) lysis, and guanidine isothiocyanate lysis, lack universality in different species, and the success rate of extracting DNA for PCR amplification is also very low. The HiPure Stool DNA Kit provided by Magen Company has opened up a new approach for DNA extraction from stool samples with good universality, high cost-effectiveness, high yield and purification. The reagent kit adopts a unique solution system and inhibitory factor adsorbent, which can efficiently remove various impurities in stool samples. The purified DNA can be directly used for PCR, quantitative PCR and other applications.
This product allows rapid and reliable isolation of high-quality genomic DNA from various stool samples. Up to 100 mg soil samples can be processed in 60 minute. The system combines the reversible nucleic acid binding properties of HiPure matrix with the speed and versatility of spin column technology to eliminate PCR inhibiting compounds such as humic acid from soil samples. Purified DNA is suitable for PCR, restriction digestion, and next-generation sequencing. There are no organic extractions thus reducing plastic waste and hands-on time to allow multiple samples to be processed in parallel.

Stool sample is homogenized and then treated in a specially formulated buffer containing detergent to lyse bacteria, yeast, and fungal samples. Humic acid, proteins, polysaccharides, and other contaminants are removed using our proprietary Absorber Solution. Binding conditions are then adjusted and the sample is applied to a DNA Mini Column. Two rapid wash steps remove trace contaminants and pure DNA is eluted in low ionic strength buffer. Purified DNA can be directly used in downstream applications without the need for further purification.

Storage and Stability
Proteinase K and Buffer PCI should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
