If you are regularly doing ChIP-qPCR, ChIP-RNAseq or luciferase reporter assays to measure protein-DNA interactions, then this article is for you! ChIP experiments can tell you what DNA sequences your protein binds, and luciferase reporter assays predict whether your protein functionally binds a specific promoter to activate transcription – but a yeast one-hybrid (Y1H) assay…
Purified proteins must be kept soluble and active. Discover how to design the perfect protein purification buffer—from additives you can include and their appropriate concentrations to important considerations.
Westerns can be tricky and time-consuming, so make the most of your precious membranes and their proteins. Learn how to properly strip off your antibodies and re-probe with another primary antibody. Why you should strip Scientific reasons: To conserve protein samples that are limited or expensive.So that you can analyse the same sample with several…
The last step in western blotting is imaging the blot – this is the moment of truth, when you finally get to see the results of the experiment you’ve been working on for so long! There are a variety of different ways to image your blot. The method you choose will largely depend on the…
Most eukaryotic proteins exist as several isoforms, differing in posttranslational modifications, which allows them to perform slightly different functions or the same function under slightly different conditions. A common posttranslational modification of proteins is glycosylation.
As a protein biochemist and a Ph.D. student, I was given the task to express a eukaryotic protein in a bacterial system. And to say that I was having a hard time would be an understatement. It took me many PCRs, cloning and transformations to get to the right construct that would eventually express the desired…
