Studying DNA–protein interactions is an important aspect of molecular biology. Researches use a variety of methods to study these like the chromatin immunoprecipitation (ChIP) assay, electrophoretic mobility shift assay (EMSA), DNA pull down assay, luciferase reporter assay, filter binding assay, yeast one hybrid system, etc. Another interesting assay that helps investigate DNA–protein interactions is the…
Viral vector production is a worthwhile skill that can be made even easier with a few tips and tricks. In general, transfection of multiple plasmids into a producer cell line results in infectious, non-replicative virus. However, it is important to ensure that your vector preparation is efficient, giving your experiments the best chance of success….
Fluorescence is one of the most important and useful tools in a biologist’s toolbox. In biology, nearly every field, from physiology to immunology, uses fluorescent molecules (aka fluorophores) to detect proteins. However, the specific science behind how fluorescence works can be confusing or overlooked. Have no fear! In this article, we break down key points of…
There are many cloning methods that do not require restriction enzymes or ligases. Read below to learn about how to achieve seamless cloning results via Topoisomerase cloning, SLIC, and Gibson. Method #1: Topoisomerase Technology Topoisomerase technology requires no special primers and no ligases – it is as easy as cloning comes. This technology is based…
The completion of the Human Genome Project in 2003 ushered in a new era of rapid, affordable, and accurate genome analysis—called Next Generation Sequencing (NGS). NGS builds upon “first generation sequencing” technologies to yield accurate and cost-effective sequencing results. Fred Sanger sequenced the first whole DNA genome, the virus phage ?X174, in 1977. In that…
