Mouse Embryonic stem cells (ESCs) were isolated from mouse (Strain C57BL⁄6) embryos at Day E3.5. Before cryopreservation, the cells were tested for viability (>70% post-thaw viability), their ability to remain undifferentiated when cultured on mouse feeder cells as assayed by marker expression (Oct4, SSEA-1, Nanog) and their ability to differentiate into embryoid bodies and express markers indicative of three germ layers (Ectoderm: (+) for β3-tubulin and nestin, Mesoderm: (+) for smooth muscle actin, Endoderm: (+) for AFP). Cells were cryopreserved at passage 20 (P20). For optimal growth perfo...

The Violet Ratiometric Membrane Asymmetry Probe⁄Dead Cell Apoptosis Kit provides a simple and fast method for the detection of apoptosis with dead cell discrimination by flow cytometry. The Violet Ratiometric Membrane Asymmetry Probe, 4'-N,N-diethylamino-6-(N,N,N-dodecyl-methylamino-sulfopropyl)-methyl-3-hydroxyflavone (F2N12S), is a novel violet excitable dye for the detection of membrane asymmetry changes during apoptosis. The dye exhibits an excited-state intramolecular proton transfer (ESIPT) reaction resulting in a dual fluorescence with two emission bands corresponding to 530 nm and 585 ...

Puromycin Dihydrochloride is an aminonucleoside antibiotic produced by Streptomyces alboniger . Puromycin works by inhibiting peptidyl transfer on both prokaryotic and eukaryotic ribosomes; resistance is conferred by the expression of the "pac" gene. Puromycin is widely used in cell biology as a selective agent in mammalian cell culture systems. The recommended working concentration ranges from 0.2 – 5.0 µg/ml, although it can be toxic to eukaryotic cells at concentrations as low as 1 µg/ml. Gibco® Puromycin Dihydrochloride is supplied at 10 mg/mL in 20 mM HEPES buffer. Life Technologies offer...

The antibiotics penicillin and streptomycin are used to prevent bacterial contamination of cell cultures due to their effective combined action against gram-positive and gram-negative bacteria. Penicillin was originally purified from the fungi Penicillium and acts by interfering directly with the turnover of the bacterial cell wall and indirectly by triggering the release of enzymes that further alter the cell wall. Streptomycin was originally purified from Streptomyces griseus . It acts by binding to the 30S subunit of the bacterial ribosome, leading to inhibition of protein synthesis and dea...

Gibco® Zeocin™ selective reagent is a formulation of phleomycin D1, a glycopeptide antibiotic produced by Streptomyces verticillus . Gibco® Zeocin™ selective reagent acts by binding to and cleaving DNA, leading to cell death. Gibco® Zeocin™ selective reagent is used for selection of yeast, bacterial and mammalian cell cultures. This product is supplied at 100 mg/ml in sterile water and is used at a working concentration ranging between 50 - 400 µg/ml depending on the cell type. Life Technologies offers a variety of antibiotics and antimycotics for cell culture applications. Product Use For Res...

Hygromycin B is a water-soluble antibiotic purified from the bacterium Streptomyces hydroscopicus . Hygromycin B acts by binding to the 80S subunit of the bacterial ribosome and inhibiting protein synthesis. Gibco® Hygromycin B is used as a bacterial selective antibiotic in the concentration range of 100 - 1000 µg / ml. This product is supplied as a 50 mg / ml solution. Resistance to Hygromycin B is conferred by the E. coli hygromycin resistance gene ( hyg or hph ). Hygromycin B uses a different mode of action than Geneticin®, Blasticidin S, or Zeocin™, so it is excellent for use in dual-selec...

Gibco® Cell Dissociation Buffer is a membrane-filtered, isotonic, and enzyme-free solution of salts, chelating agents, and cell-conditioning agents in calcium-free and magnesium-free phosphate-buffered saline (PBS). Gibco® Cell Dissociation Buffer is suitable for the gentle dissociation of mammalian cells for studies such as ligand binding, flow cytometry, and immunohistochemistry, that require intact cell surface proteins. Gibco® Cell Dissociation Buffer works well with lightly adherent cell lines, such as HeLa and NIH 3T3, but is not recommended for the routine passaging of strongly adherent...

Gibco® Drosophila S2 cells are used for heterologous protein expression in the DrosophilaM Expression System (DES®). The S2 cell line was derived from a primary culture of late stage (20-24 hours old) Drosophila melanogaster embryos. Many features of the S2 cell line suggest that it is derived from a macrophage-like lineage. S2 cells grow at room temperature in ambient CO 2 as a loose, semi-adherent monolayer in tissue culture flasks and in suspension in spinners and shake flasks. Drosophila S2 cells (frozen in Gibco® Schneider's Medium) feature: • Expression of protein transiently or through ...
