The EPL picosecond pulsed diode lasers are a new excitation source for fluorescence lifetime measurements that bridge the gap between the nanosecond flashlamp and expensive mode locked Titanium Sapphire femtosecond lasers. The EPL lasers are pre-adjusted for an optimum pulse width, with particular attention paid to reducing a secondary shoulder. The output has a guaranteed pulse width of less than 100 picoseconds. The EPL lase…

The EPLED picosecond pulsed LEDs are a new excitation source for fluorescence lifetime measurements. In Time Correlated Single Photon Counting (TCSPC), they bridge the gap between the nanosecond flashlamp and expensive mode locked Titanium Sapphire femtosecond lasers in the UV region. The EPLEDs are pre-adjusted in respect to pulse width and peak power, with particular attention paid to reducing both secondary shoulder and a l…

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…
