Gentamicin sulphate
Supplier: MP Biomedicals
Gentamicin is an aminoglycoside antibiotic complex produced by fermentation of Micromonospora purpurea or M. echinospora. It is a mixture of 3 major components designated as C1, C1a, and C2. Gentamicin is used as the sulfate salt. Each component consists of five basic nitrogens and requires five equivalents of sulfuric acid per mole of gentamicin base. Mode of action: Gentamicin causes codon misreading by binding to the 30S ribosomal subunit, blocking the translocation of peptidyl-tRNA from the acceptor site to the donor site.The bactericidal effect of gentamicin on Pseudomonas aeruginosa is exerted by the binding of gentamicin to the outer membrane, where it displaces natural cations, destabilizes the membrane, and forms holes in the cell surface.Antimicrobial spectrum: Gram-negative bacteria, Staphylococcus aureus and other Gram-positive bacteria. Gentamicin sulfate is a broad spectrum antibiotic. It inhibits the growth of a wide variety of Gram-positive and Gram-negative microorganisms, including strains resistant to tetracycline, chloramphenicol, kanamycin, and colistin, particularly strains of Pseudomonas, Proteus, Staphylococcus, and Streptococcus. Gentamicin sulfate inhibits bacterial protein biosynthesis by binding to the 30S subunit of the ribosome.

3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) ≥98%, yellow powder cell culture reagent
Supplier: MP Biomedicals
Storage: +4°C, protect from light
3- (4,5-Dimethyl-2-thiazolyl-2)-2,5-diphenyl-tetrazolium bromide is used as a colorimetric metabolic activity indicator in cell viability assays. Thiazolyl Blue Tetrazolium Blue (MTT) is a dye used in measurement of cell proliferation. MTT produces a yellowish solution that is converted to dark blue, water-insoluble MTT formazan by mitochondrial dehydrogenases of living cells. The blue crystals are solubilized with acidified isopropanol and the intensity is measured colorimetrically at 570 nm. MTT has been used as a histochemical/cytochemical reagent and for the detection of NAD. ADP-linked enzyme systems in tissue cannot be detected with MTT, due to binding of the cation by the cyanide trap used. MTT is rapidly reduced to the formazan, which chelates with nickel, copper, and cobalt; the cobalt chelate has been used in oxidative systems.

Cetrimonium bromide ≥98% for molecular biology
Supplier: MP Biomedicals
Cetyltrimethylammonium bromide is a phase transfer catalyst ideal for the precipitation of DNA. Hexadecyltrimethylammonium bromide is a bactericidal, cationic detergent. Its activity is neutralized by soaps and anionic detergents (i.e., SDS). Trimethylammonium bromide compounds form insoluble complexes with SDS. It is active at alkaline pH against both Gram positive and Gram negative organisms.
Cetyltrimethylammonium bromide ia used as an cationic surfactant suitable for the isolation of high molecular weight DNA in plants and other organisms(by a rapid method) as well as plant DNA for use in PCR analysis. It has been used to precipitate nucleic acids. CTAB provides enhancement of Concanavalin A mediated agglutination. It has been used for the determination of protein molecular weights in electrophoretic systems and for determination of critical micelle concentration of detergents. CTAB has also been used as a titrant for potentiometric titration of perchlorate and as a phase-transfer catalyst in reduction of arenes and heterocyclic compounds.

2,3,5-Triphenyltetrazolium chloride (TTC), white powder
Supplier: MP Biomedicals
2,3,5-Triphenyltetrazolium Chloride is a redox indicator. In the TTC assay (also known as TTC test or tetrazolium test), TTC is used to differentiate between metabolically active and inactive tissues. The white compound is enzymatically reduced to red TPF (1,3,5-triphenylformazan) in living tissues due to the activity of various dehydrogenases (enzymes important in oxidation of organic compounds and thus cellular metabolism), while it remains as white TTC in areas of necrosis since these enzymes have been either denatured or degraded.
2,3,5-Triphenyltetrazolium Chloride is commonly used in biochemical experiments especially to indicate cellular respiration. TTC has been employed in autopsy pathology to assist identification of post-mortem myocardial infarctions. Healthy viable heart muscle will stain deep red from the cardiac lactate dehydrogenase; while areas of potential infarctions will be more pale. Useful indicator for reducing substances

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.

E.Z.N.A.® Endo-Free plasmid mini kit II
Supplier: OMEGA BIO-TEK
Plasmid isolated with traditional purification procedures normally contain high levels of endotoxins (also known as lipopolysaccharides or LPS) that can significantly interfere with transfection experiments downstream. The E.Z.N.A.® Endo-Free plasmid mini kit II integrates an efficient endotoxin removal step into the plasmid purification procedure to produce high-quality transfection grade (<0,1 EU/µg) plasmid for efficient transfection. The bacterial cells are lysed using the alkaline-SDS lysis method. The cleared cell lysate is then treated with ETR reagent to efficiently remove the endotoxins. After adjusting the binding condition, the cell lysate is applied into the HiBind® DNA column and purified DNA is eluted from the column membrane.
