TFPN [tetrafluorophthalonitrile, 3,4,5,6-tetrafluorophthalonitrile] has in recent years been used for amide bond and peptide bond formation under carboxylic acid activation conditions. Published studies have shown that this route can be applied to sterically hindered substrates and difficult ...
Antibiotic selection in molecular cloning is not merely a preliminary judgment based on the presence or absence of colonies. Rather, it is a fundamental control point for plasmid maintenance stability, insert integrity, dual-plasmid coexistence, and the reliability of downstream expression. ...
The key to primary cell isolation does not lie in simply increasing the speed at which a tissue is “digested open,” but rather in establishing a controllable balance among extracellular matrix dissociation, loosening of cell-cell junctions, and dispersion of tissue fragments, while ...
2-Chloro-1-methylpyridinium iodide, abbreviated as CMPI, is a representative member of Mukaiyama-type carboxylic acid activation reagents and is often referred to as a Mukaiyama reagent; more precisely, it is one of the classic representatives of Mukaiyama-type 2-halo-1-methylpyridinium ...
In the preparation of peptides and amino acid derivatives, the Fmoc (9-fluorenylmethoxycarbonyl) protection strategy is already highly mature. Merrifield established the basic framework of solid-phase peptide synthesis (SPPS), and Carpino subsequently introduced the Fmoc protecting group, which ...
In the precipitation of low-concentration, low-copy, or highly diluted nucleic acid samples, precipitation efficiency is determined not only by ethanol, isopropanol, and salt systems, but also by whether the system contains a coprecipitant capable of improving nucleation efficiency, stabilizing ...
2-Azido-1,3-dimethylimidazolinium hexafluorophosphate (ADMP) can directly convert primary amines into organic azides under conditions that do not require the addition of an external metal catalyst. Existing studies have shown that this transformation is quite sensitive to substrate type, and ...
Once a cell sample enters a preservation system, the analytical result is no longer determined solely by its original biological state, but is instead jointly influenced by the anticoagulation mode, osmotic environment, buffering conditions, degree of metabolic suppression, and processing ...
Differences in cytotoxicity evaluation arise first from differences in the biological process being measured. The Neutral Red assay primarily reflects cellular uptake of the dye and lysosomal retention capacity, whereas the MTT assay and the CCK-8 assay mainly reflect dehydrogenase-related ...
