STEMCELL Technologies Hygromycin B, Size: 100 mg

Hygromycin B, an aminoglycoside antibiotic, inhibits the growth of prokaryotic and eukaryotic cells. Specifically, it inhibits protein synthesis by interfering with translocation of the 70S ribosome subunit and inducing misreading of the mRNA template. Hygromycin B has been used to select transfectants in a wide variety of cells including bacteria, protozoans, yeast, fungi, plants, and mammalian cells. Resistance to Hygromycin B is conferred by a gene coding for a phosphotransferase that phosphorylates Hygromycin B, thereby inactivating it. Hygromycin B is an effective agent for the selection and maintenance of bacterial and eukaryotic cells stably transfected with vectors containing E. coli Hygromycin B resistance gene (hyg or hph). This antibiotic is suitable for use in cell culture for the selection of hygromycin-resistant clones when using ClonaCell™-TCS Medium (Catalog #03814), and for the selection of any hygromycin-resistant transfected cell type.

Apexbio Technology LLC Elesclomol (STA-4783),5mg CAS# 488832-69-5

Elesclomol (also known as STA-4783), originally identified in a cell-based phenotypic screen for proapoptotic activity, is a novel small-molecule that potently induces apoptosis of cancer cells through the rapid generation of reactive oxygen species (ROS) and the induction of unmanageable levels of oxidative stress. Elesclomol exhibits autitumor activity against a broad spectrum of types of cancer cell in human tumor xengograft models due to its excessive ROS production and elevated levels of oxidative stress leading to the death of cancer cells. Other sizes are also available. Please inqury us for quote.

Gold Biotechnology Inc Carbenicillin (Disodium), USP Grade 50 g

Carbenicillin is a member of the penicillin β-lactam antibiotics. However, unlike most β-lactams, carbenicillin disodium is limited to primarily gram-negative bacteria including Pseudomonas aeruginosa and common enteric species. It can be used in selection protocols and is often preferred over ampicillin due to its increased stability. This allows for less contamination of unwanted bacterial colonies. In addition, carbenicillin has been used to regulate bacterial growth in plants, yielding low regeneration frequencies. It can be used in genetic transformation applications to select for AmpR transformed cells.
