ATP-polyamine-biotin is a cell-permeable, efficient kinase cosubstrate with conversions and kinetics similar to those of other known ATP analogues. APB shows a cytotoxicity EC50 value of 19 ± 1 mM. ATP-polyamine-biotin is shown to promote biotin labeling
CDy9 is a highly selective fluorescent probe for the detection and isolation of mESC using fluorescence microscopy and flow cytometry. CDy9 allows the detection and isolation of intact stem cells with marginal impact on their function and capabilities. CD
α-Cyclodextrin (α-CD) is a saccharide comprised of six glucose subunits linked by α-1,4 bonds, which results in a cone-shaped molecule.1It contains a hydrophobic interior and hydrophilic exterior, which allow it to form inclusion complexes with wide variety of molecules, conferring enhanced solubility and stabilization to the molecules. α-CD has commonly been used in the separation and purification of chemicals on an industrial scale.1,2Formulations containing α-CD have been used in the pharmaceutical industry to improve the physical and chemical properties of compounds, the food industry as flavor carriers and stabilizers in processed and ultra-processed foods and certain beverages, as well as in other industrial applications. 1.Li, S., and Purdy, W.C.Cyclodextrins and their applications in analytical chemistryChem.

Isoprostanes are prostaglandin (PG)-like products of free-radical induced lipid peroxidation. Although the isoprostanes derived from arachidonic acid are the best characterized, many other polyunsaturated fatty acids can form isoprostanes. (±)5-iPF2α-VI is one of dozens of possible stereo- and regioisomeric isoprostanes which can be formed from arachidonic acid. To date, the most extensively studied of these is 8-isoprostane (8-epi-PGF2α, iPF2α-III). However, 8-isoprostane is a minor isoprostane constituent when compared to some of the other isomers which form in natural conditions of oxidative stress. (±)5-iPF2α-VI is an isoprostane from the unique Type VI class of isoprostanes. This class has been shown to be one of the major isoprostane products, in contrast to 8-isoprostane. In addition to being produced in greater abundance than 8-isoprostane, Type VI isoprostanes form internal lactones, which facilitates their extraction and purification from biological samples.
Carbazomycin A is a bacterial metabolite that has been found in Streptomyces and has diverse biological activities.1,2It is active againstS. aureus,T. asteroides, andT. mentagrophytes(MIC = 12.5 μg ml for all), as well as the plant pathogenic fungusP. oryzae(MIC = 25 μg ml). Carbazomycin A is cytotoxic to MCF-7, KB, NCI H187, and Vero cells (IC50s = 26.2, 30.1, 18.4, and 32.6 μg ml, respectively).2 1.Sakano, K.-I., Ishimaru, K., and Nakamura, S.New antibiotics, carbazomycins A and B.

FP-biotin is a potent organophosphorus toxicant, ideal for identifying novel biomarkers of organophosphorus toxicant exposure. It measures FAAH, ABHD6, and MAG-lipase activity, specifically in plasma studies, due to the efficient purification of biotinylated peptides through binding to immobilized avidin beads.
