Products & Reviews

For perfect high-performance liquid chromatography (HPLC) results, high-performance solvents are a must. LiChrosolv ® solvents are designed to optimally support analytical HPLC, fast chromatography, and LC-MS applications. They feature high degrees of UV transmittance, low particle counts, low acidity and alkalinity, and low evaporation residue levels making them ideal for reproducible separations.

Steripak-GP filter units are designed for larger scale pressure-driven filtration of tissue culture media with or without serum. They are single use and are not autoclavable. The filter units come in two sizes, with the smaller unit able to filter up to 10 L and the larger up to 20 L. Both sizes utilize the low protein binding, fast flow 0.22 µm EMD Millipore Express membrane.

Steritop bottle top filter units provide a large filter area for rapid sterile filtration of aqueous fluids into narrow-mouth (33 mm) or wide-mouth (45 mm) bottles. A small tab inside the funnel secures an optional prefilter in-place during filtration. For added protection against contamination, the threads for bottle attachment have been slightly recessed in case the funnel accidentally touches a work surface

Chromatin Immunoprecipitation (ChIP) is an important technique allowing the researcher to analyze in vivo interactions of proteins with genomic DNA. Any chromatin-associated or DNA binding protein can be analyzed with this technique, provided a good antibody to the protein exists. One can measure different proteins localized to a specific region of the genome, or the genome wide distribution of a specific protein. Another powe…

The EZ-Zyme™ Chromatin Prep kit allows ChIP analysis at nucleosome resolution by performing complete or partial digestions with a proprietary enzymatic cocktail to obtain chromatin fragments of on average one to a few nucleosomes in length. Compared to sonication, this procedure not only allows mapping the protein-DNA association at a higher resolution, but also renders the subsequent immunoprecipitation more efficient due to…

Sterivac vacuum-driven filter units are ideal for bottle-top filtering directly into receiver flasks at flow rates as fast as 1.5 L/min. The unique "start & stop" filtration action makes setting up, filtering and transferring the unit to another receiver fast and easy. Push a button to stop filtering, move the device to an empty bottle and restart

The CpGenome™ DNA Modification Kit is used to create methylation-specific sequence alterations in any DNA sample. Using chemical treatment, the kit converts all unmethylated cytosine residues to uracil. Methylated cytosine residues are unaltered in this process. Therefore, the chemically-treated DNA sequence will differ only if it was originally unmethylated in vivo. After sequence conversion, methylation specific PCR is emplo…

The CpGenome™ Fast DNA Modification Kit contains the reagents for the initial bisulfite modification of the DNA required for both methodologies.

ChIP-Seq facilitates genome-wide profiling of the interactions of transcription factors, modified histones, and other chromatin associated proteins. By combining chromatin immunoprecipitation with next generation sequencing, laboratories can generate high resolution data on protein-DNA interactions across the genome. For laboratories interested in gaining a deeper understanding of epigenetic mechanisms of gene regulation, ChIP…

With inherent amide bond detection, the Direct Detect™ system distinguishes proteins and peptides from interfering sample components, providing more accurate results without the pitfalls of colorimetric assays. Technology: FTIR Spe…

Indispensable for NMR spectroscopy Unlocking the molecular structure of organic molecules is central to understanding how they interact with other molecules. This is especially critical in genomics, proteomics and drug discovery research. The Nuclear Magnetic Resonance (NMR) technique allows scientists to “see” molecular structure and dynamics. MagniSolv™ deuterated solvents are a key tool for the NMR technique. MagniSolv™ deu…
