Dimethyl sulphoxide for molecular biology
Supplier: MP Biomedicals
Storage: Room Temperature, desiccate, store under nitrogen.
Dimethyl Sulfoxide is a dipola, aprotic solvent. It has been shown to accelerate strand renaturation (1-10% concentration) and is believed to give the nucleic acid thermal stability against depurination.
Dimethyl Sulfoxide is used to enhance dermal absorption of many chemicals, as a solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers, in antifreeze or hydraulic fluids, as a cryopreservative for cell cultures, oxidation of thiols and disulfides to sulfonic acids, as a PCR cosolvent to help improve yields, especially in long PCR. DMSO is routinely used in polymerase chan reaction (PCR), amplification of cDNA libraries, DNA sequencing, column-loading buffers for poly (A)+ RNA selection, buffers for the transformation of competent E. coli, and transfection protocols.
To prepare sterile solutions use a teflon or nylon membrane to sterile-filter the DMSO - do not use a cellulose acetate membrane.

Glycine ≥99% for molecular biology
Supplier: MP Biomedicals
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.

Robotic tips (CO-RE Tips) and consumables for Microlab
Supplier: HAMILTON ROBOTICS
Hamilton CO-RE tips were designed for MICROLAB pipetting workstations in order to solve the problem of sealing and alignment plagued by press-fit tip attachment techniques. Each CO-RE disposable tip has a circular groove inside the attachment orifice. An o-ring on the pipetting channel is expanded to fit this groove precisely providing an air-tight seal and straight alignment between tip and pipetting channel.

Ampicillin sodium salt, white powder, Cell Culture Grade
Supplier: MP Biomedicals
Ampicillin sodium salt is a semi-synthetic derivative of penicillin, active as a broad-spectrum antibiotic. It is inactivated by beta-lactamases and for this reason a beta-lactamase inhibitor should be considered when using ampicillin. Against gram-positive bacteria, ampicillin has a similar mode of action as benzylpenicillin; against gram-negative bacteria, it has a similar mode of action as chloramphenicol and tetracyclines. In E. coli it inhibits cell wall synthesis.
