Supplier: MACHEREY-NAGEL

Silica based phases for HPLC enantiomer separation in which CHIRAL-1 seperation is based on ligand exchange and CHIRAL-2 or CHIRAL-3 on charge-transfer and further interactions as well as on steric effects.

Supplier: Thermo Fisher Scientific

Alcohol dehydrogenase catalyses the reaction: RCH₂OH +NAD⁺ → RCHO + NADH + H⁺. It facilitates the interconversion between alcohols and aldehydes or ketones with the reduction of nicotinamide adenine dinucleotide (NAD+ to NADH). In biotransformation, alcohol dehydrogenases are often used for the synthesis of enantiomerically pure stereoisomers of chiral alcohols.

Supplier: Resonac

Glycine is a non-essential amino acid. Acts as an inhibitory neurotransmitter, particularly in brain stem and medulla. Shown to block NMDA-stimulated dopamine release in fetal mesencephalic cell cultures. Also reported to increase NMDA-receptor mediated synaptic potential in cortical neurons. It does not have a chiral center, so only amino acid with no asymmetric carbon. Therefore, it does not have a D- or L- isomer designation. This material is synthetic. It is the smallest of the 20 natural amino acids.

Supplier: MACHEREY-NAGEL

Cyclodextrin modified silica phases for HPLC enantiomer separation. These phases are especially suited for the control of optical purity and for the analysis of positional and cis-trans isomers.

Storage: Store at Room Temperature (15-30 °C)
Glycine is a non-essential amino acid. It is only amino acid with no asymmetric carbon and thus is not chiral. It is the major inhibitory neurotransmitter. It is involved in the biosynthesis of the porphyrin rings of hemes and chlorophylls.
Glycine is commonly used in buffer solutions, in electrophoresis and preparative chromatography. A study of the folding of monoclonal antibodies in the presence of glycine and their subsequent purification has been published. The use of glycine in the purification of lipopolysaccharides, lipooligosaccharides, and lipid A has been reported. It is an amino acid for use in cell culture media development applications and existing media formulations. Glycine is commonly used as a component in Tris-glycine and Tris-glycine-SDS running buffers for polyacrylamide gel electrophoresis, a component of Towbin's transfer buffer for Western blots, a buffer substance in cryoenzymology, in osmotic pressure maintenance in isoelectric focusing of erythrocytes, salting-in effect in protein chemistry, and as a buffer component in the coupled phosphatase-kinase reaction for end labelling of restriction fragments. The growth requirements of various microorganisms is reported in the Handbook of Microbiology.
Glycine is a non-chiral amino acid that can be synthesized in the body from the amino acid serine by Serine Hydroxymethyltransferase. Inhibitory neurotransmitter in spinal cord, allosteric regulator of NMDA receptors.

L-Asparagine is used in cell culture media and is a component of MEM non-essential amino acids solution. L-Asparagine has been shown to enhance ornithine decarboxylase activity in cultured human colon adenocarcinoma Caco-2 cells and in cultured IEC-6 intestinal epithelial cells. Spore germination in Bacillus subtilis has been increased in the presence of L-asparagine. An isoxazoline RGD mimic platelet GPIIb/IIIa antagonist has been prepared by chiral synthesis with L-asparagine as a starting material. L-Asparagine has been utilized in the synthesis of 4-azalysine building blocks for application to combinatorial chemistry.
