For many assays, it is necessary to quench or stop the reaction at a specific time to prevent further production of product. For example, samples may be taken at 5-minute intervals for a predetermined period of time and the product measured by HPLC. Each chromatographic analysis may take 30 minutes to complete.

Oct 22, 2019 · Background Gene set analysis is a well-established approach for interpretation of data from high-throughput gene expression studies. Achieving reproducible results is an essential requirement in such studies. One factor of a gene expression experiment that can affect reproducibility is the choice of sample size. However, choosing an appropriate sample size can be difficult, especially because

Jul 15, 2020 · Some specialized collection media (such as thioglycolate broth) are so labile that indicator dyes are added to show when a vial of medium is no longer usable. 2 In addition, the majority of collection media are not subject to quality control testing by users (i.e., the laboratory) and are considered exempt under the National Committee for

– Halve your analysis time by reducing sample analysis delays – Reduce sample consumption—with less delay throughout analysis and less sample waste – Save labor and reduce running costs—the more elements you determine, the more you save on gas, reagents, and lamps – Further analysis time reduction when combined with

Jun 15, 2020 · The closer the agreement between individual analyses, the more precise the results. For example, the results shown in the upper half of Figure \(\PageIndex{1}\) for the concentration of K + in a sample of serum are more precise than those in the lower half of Figure \(\PageIndex{1}\). It is important to understand that precision does not imply

It’s important to consider reliability and validity when you are creating your research design, planning your methods, and writing up your results, especially in quantitative research. Failing to do so can lead to several types of research

May 30, 2023 · Accurate and consistent vial filling is critical to reliable analysis. Filtration techniques like pipetting or automated filling systems should be utilized to ensure the appropriate amount of sample is added into each vial; overfilling or underfilling can result in inaccurate results, so precise measurements must be maintained at all times.

Why gamble with your results? Using poor-quality vials (or the wrong vials for your application) can cause sequence problems, unnecessary downtime, expensive repairs, and the loss of precious samples Aijiren vials are the only vials that deliver time and cost savings: • Reduced labor: Our short-thread screw-top vials make screwing/

Robust DNA extraction removes inhibitors and helps improve the overall yield, concentration and purity of DNA isolated from both routine and challenging samples. Advanced quantification kits deliver accurate results in less time, for even the most challenging casework samples. Both workflows are essential for improving downstream success.
