Hygromycin B (from Streptomyces hygroscopicus), >1000 u/mg ≥95%, white powder

Supplier: MP Biomedicals

Hygromycin B is an antibiotic substance isolated from Streptomyces hygroscopicus. Its mode of action is the inhibition of protein synthesis, by inducing the misreading of the m-RNA template in the prokaryote, (E. coli, at 100 mg/mL), lower eukaryotes (e.g., yeast, at 200 mg/mL) and higher eukaryotes (e.g., mammalian cells in culture). It selectively penetrates cells that have been rendered permeable by virus infection and combined with its potency to inhibit translation, it is an effective antiviral agent. Hygromycin B can be used as a dual-selection antibiotic when used in conjunction with G418 or Zeocin™ for cells transfected with two different vectors.

Glycerine ≥99%, clear colorless viscous liquid cell culture reagent

Supplier: MP Biomedicals

Storage: Store at Room Temperature (15 - 30 °C)
Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel’s sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component. Glycerol is used in the concentration and storage of enzymes. Also prevents back-diffusion and protein samples into the buffer. Ideal for use as a cryoprotectant.

Polyethylene glycol 8,000, white prills for molecular biology

Supplier: MP Biomedicals

Polyethylene glycol (PEG) is a condensation polymer of ethylene oxide and water.
Polyethylene Glycol has been used in the precipitation of proteins, as a fusing agent in enhancing the effect of macrophages on hybridoma, in the separation and purification of biomolecules and in induction of cell hybridization.
PEG's are susceptible to oxidative degradation in the presence of air. Minimizing the exposure of PEG to elevated temperatures and/or exposure to oxygen, or addition of an antioxidant can limit the amount of degradation. PEGs do not hydrolyze or deteriorate upon storage. PEGs do not support the growth of molds.

Copper(II) acetate monohydrate

Supplier: Aladdin Scientific

Copper (II) acetate monohydrate is soluble in water and slightly soluble in methanol, diethylether and acetone. It can be synthesized by reacting acetic acid with copper (II) carbonate or copper(II) hydroxide or copper (II) oxide. Large scale commercial production is undertaken by placing copper metal in the presence of air and refluxing acetic acid. As a transition metal acetate, it can be used to form oxide nanoparticles by sonochemical methods.Used in the synthesis of copper oxide nanoparticles,1 Cu2ZnSnS4 films, which find applications in solar cells.2 It may be used in Zinc Oxide varistors, as a catalyst in the polymerization of organic materials and as a mordant in the dying of textiles. Industrially, it may be used as a ceramic pigment and as a fungicide.

1,1,1,3,3,3-Hexafluoro-2-propanol ≥99%, clear liquid

Supplier: MP Biomedicals

1,1,1,3,3,3-Hexafluoro-2-propanol is polar and exhibits strong hydrogen bonding properties enabling it to dissolve substances that serve as hydrogen-bond acceptors. 1,1,1,3,3,3-Hexafluoro-2-propanol is a polar solvent of high ionizing power and facilitates Friedel–Crafts-type reactions, using covalent reagents in the absence of a Lewis acid catalys. 1,1,1,3,3,3-Hexafluoro-2-propanol clusters catalyzes the epoxidation of cyclooctene and 1-octene with hydrogen peroxide.
It is a speciality solvent effective for solubilizing a wide range of polymers, including those that are not soluble in the most common organic solvents: such as polyamides, polyacrylonitriles, polyacetals, polyesters (e.g. polyglycolide), and polyketones. It has also found use in biochemistry to solubilize peptides and to monomerize β-sheet protein aggregates. It can be used as an acid in volatile buffers for ion pair HPLC - mass spectrometry of nucleic acids. 1,1,1,3,3,3-Hexafluoro-2-propanol was used for preparing hexafluoroalcohol-functionalized methacrylate polymers for lithographic/nanopatterning materials.

Piperacillin Sodium Salt, white powder

Supplier: MP Biomedicals

Piperacillin is a semisynthetic, broad-spectrum ureidopenicillin antibiotic. It is derived from ampicillin. Piperacillin inhibits the last stage of bacterial cell wall synthesis by binding to certain penicillin-binding proteins (PBPs), which results in cell lysis. Cell lysis is mediated by bacterial cell wall autolytic enzymes. Piperacillin may interfere with autolysin inhibitors.
It has been used in pharmacokinetic studies in order to optimize antimicrobial therapy in patients with sepsis. It is used to study piperacillin hypersensitivity reactions and to study multidrug-resistant organisms.

Ciprofloxacin hydrochloride monohydrate

Supplier: MP Biomedicals

Ciprofloxacin is a fluorinated quinolone antibacterial agent which is highly effective against a broad spectrum of bacteria and mycoplasma.
Ciprofloxacin is most commonly used to treat infections of the skin, bone, sinus, lung, abdomen, and bladder. It can also be used to treat some sexually transmitted infections. Additionally, ciprofloxacin can be used after exposure to inhalation anthrax to reduce the chance of developing an infection.
During the proliferation phase of a bacterium a segmental twisting and untwisting of the chromosomes take place. An enzyme called DNA gyrase plays a decisive part in this process. Ciprofloxacin inhibits this DNA gyrase in a way that arrests the bacterial metabolism, since vital information can no longer be read from the bacterial chromosome. Ultimately, it affect DNA replication & cell division.
Store at +4 °C.

Kanamycin sulfate, white powder, Cell Culture Grade

Supplier: MP Biomedicals

Kanamycin sulfate is an antimicrobial agent effective against Gram-negative and Gram-positive bacteria and mycoplasma. It binds to the 70S ribosomal subunit, inhibits translocation, and elicits miscoding. Cross-resistance occurs between kanamycin and neomycin, framycetin, and paromomycin, and partial cross-resistance has been reported between kanamycin and streptomycin. Aminoglycosidemodifying enzymes (acetyltransferase, phosphotransferase, nucleotidyltransferase) alter the antibiotic, preventing its interaction with ribosomes.
