GC Columns, Rt-bDEXse™ (fused silica)

Leverandør: Restek
Beskrivelse: Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and DEX columns continue to demonstrate stability after hundreds of temperature program cycles. By adding β or γ cyclodextrin to our bonded Rtx-1701 stationary phase, we greatly enhance overall utility and column lifetime for our chiral columns, compared to columns that have pure cyclodextrin stationary phases. 2,3-di-O-ethyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin added into 14% cyanopropylphenyl/86% dimethyl polysiloxane

Human Recombinant Deoxycytidine Kinase (from E. coli)

Varenummer: (PRSI92-064)
Leverandør: ProSci Inc.
Beskrivelse: Deoxycytidine Kinase (DCK) is a member of the DCK/DGK family. DCK exists as a homodimer and is localised to the nucleus. DCK is required for the phosphorylation of the deoxyribonucleosides deoxycytidine (dC), deoxyguanosine (dG), and deoxyadenosine (dA). DCK has broad substrate specificity, and does not display selectivity based on the chirality of the substrate. In addition, DCK is also an essential enzyme for the phosphorylation of numerous nucleoside analogs widely employed as antiviral and chemotherapeutic agents. DCK is clinically important because of its relationship to drug resistance and sensitivity.

Glycin ≥98%, pulver

Leverandør: MP Biomedicals
Beskrivelse: 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.

Glycin ≥99% til molekylærbiologi

Leverandør: MP Biomedicals
Beskrivelse: 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(+)-Asparagin, vandfri ≥99%, white powder cell culture reagent

Leverandør: MP Biomedicals
Beskrivelse: Storage: Store at Room Temperature (15-30 °C). Store Desiccated.
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.
