Product news
GE Healthcare has launched Streptavidin Mag Sepharose magnetic beads, which have a high binding capacity for efficient purification of biotinylated biomolecules and enrichment of target proteins. The magnetic beads provide simplified handling, as rapid capture is facilitated by magnetic devices whilst delivering scalability and high yield, from low microlitre to high milliliter scale sample volumes.
Streptavidin Mag Sepharose beads support reliable sample preparation for downstream analysis and have a more than 400 fold enrichment factor to enable an increased identification rate of target proteins. The magnetic beads are hydrophilic with a high density to ensure the beads do not aggregate, so avoiding sample loss and increasing yield. Available in two pack sizes, 2 x 1ml and 5 x 1ml.
In addition, GE Healthcare has launched the MagRack Maxi. This new magnetic rack provides easy handling and supports sample capacities of up to 50ml, to provide capture of low-expressed target proteins from larger sample volumes. MagRack Maxi is a direct-scale up of the MagRack 6, used for small-scale purification. The MagRack Maxi consists of an anodized aluminium housing with a detachable plastic bar containing a neodymium magnet, one 15ml tube and one 50ml tube can be placed in the rack.
Combined these new products offer a reliable and easy-to-use solution to sample preparation.

Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins. Find the best cell and tissue culture products, kits and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Genome AnalysisGenomics, the study of genomes, includes functional genomics, evolutionary genomics and comparative genomics. There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.OligonucleotidesOligonucleotides are small nucleic acid polymers, usually less than 20 bases in length. Oligonucleotides can be made via enzymatic cleavage or more commonly by chemical synthesis with polymerases. Their use includes FISH, southern blots, microarrays and as primers in PCR. High fidelity synthesis kits and detection systems are available for easy production and detection, respectively.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Cell Lines Stem Cells and Primary CellsPrimary cell cultures, established cell lines and stem cells are vital for <i>in vitro</i> and <i>ex vivo</i> experimentation. High-quality cells, optimized for your applications, alongside optimized cell substrates, growth medium and supplements, are critical for experimental success. Explore a range of cells suitable for your applications, including isogenic cell lines, competent cells, induced pluripotent stem cell (iPSC)-derived cell lines, fungal/bacterial/mammalian cell lines, stem cells and cancer cell lines.

Explore a range of a gel imaging systems, densitometers, scanners, transilluminators or UV lamp + CCD cameras for your image analysis solutions. Colorimetric, fluorescent and/or radioisotopic samples can be visualized and documented for further analysis. See gel doc / Image analysis software for quantitative 1D and 2D analysis of your samples.

Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.

The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :
