Use this reference table to find the coupling values and chemical shifts of our NMR (deuterated) solvents. Melting and boiling points, molecular weight, density, and CAS number are also listed.
C2-symmetric chiral bisoxazolines (BOX) are privileged structures because they promote a great number of transformations with unprecedented selectivity.1
Human epithelial intestinal colonic organoids can be used as an alternative to Caco-2 drug permeability assays for drug screening and compound toxicity testing.
Research involving reactive silicone chemistry has focused on the production of pure silicon and hybrid materials, hydrosilylation, ring-opening and atom transfer polymerizations, polymerizations with controlled stereochemistry, and condensation reactions.
Glycosyltransferases were initially considered to be specific for a single glycosyl donor and acceptor, which led to the one enzyme-one linkage concept. Subsequent observations have refuted the theory of absolute enzymatic specificity by describing the transfer of analogs of some
Pistachios contain approximately 45% fat, which can result in a significant amount of coextracted matrix in the acetonitrile extract generated using the QuEChERS procedure. A zirconia based adsorbent significantly reduces coextracted matrix prior to LC-MS or GC-MS.
A procedure for cleanup of green tea extracts provides low background and allowed for the analysis of more pesticides at lower levels than QuEChERS. Uses less solvents and no toluene.
Advanced KSOM mouse embryo media that can be used as a single medium for both harvest and culture of mouse embryos to facilitate creation of transgenic knockout mice.

The soaring global demand for energy, coupled with the limited supply of fossil fuels, has increased the need for renewable, low-cost energy sources. Organic electronics have shown great promise for applications in lighting, power, and circuitry, with rapidly improving performance
Currently, magnetic nanoparticles (MNPs) are attracting a lot of attention because of the possibility of many novel applications, especially in biomedical research.
HILIC mode chromatography using an Ascentis® Express OH5 resolved the majority of the acyl-L-carnitines tested. It may be possible to use MS/MS and particular fragment ions to resolve the two coeluting pairs.
Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
We provide an overview of our available reagents, together with recommendations and details of their use for synthesis of peptides containing post-translationally modified amino acids.
Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.
DNA damage and repair mechanism is vital for maintaining DNA integrity. Damage to cellular DNA is involved in mutagenesis, the development of cancer among others.
Use the calculator to determine the boiling point or pressure of solvents based on the Antoine Equation and see solvent attributes. View a list of products based on the solvent CAS number.
For several decades, the need for an environmentally sustainable and commercially viable source of energy has driven extensive research aimed at achieving high efficiency power generation systems that can be manufactured at low cost.
Immunohistochemistry (IHC) techniques and applications have greatly improved, dermatopathology is still largely based on H&E stained slides.This paper outlines ways in which IHC antibodies can be utilized for dermatopathology.
