Efficient Electrophoresis and Protein Blotting: Aiding Advances in Cardiomyopathy Research

 :: Posted by American Biotechnologist on 11-17-2011

A native of Trinidad and Tobago, Dr Aldrin Gomes decided to specialize in the biochemical differences between normal and diseased hearts in his graduate studies at the University of the West Indies. A significant portion of his research utilized protein separation and purification techniques, making SDS-PAGE electrophoresis and protein blotting an essential tool in most of his experiments. But in a country where resources are scarce, unrelenting heat is destructive to sensitive biological materials, and slow delivery times are common for product orders, Gomes and his colleagues began to analyze the electrophoretic workflow to determine how to make the process as efficient as possible. “Because we performed a lot of electrophoresis, we published some articles whereby we looked at how we could standardize things to improve resolution in our results,” says Gomes. “We heavily researched aliquoting methods, sample buffers (methods for making them and determining actual shelf lives), whether or not buffers can be reused — even minor factors such as gel pouring techniques and plate thickness.”

Since Gomes “grew up,” scientifically speaking, in an environment where experiments must be planned far in advance and resources cannot be wasted, he cultivated the habit of designing experiments and procedures that made the best possible use of tools and time while ensuring optimal results. This followed him through his graduate work and his subsequent career, first as a research associate, then in his current role as assistant professor in the Neurobiology, Physiology and Behavior department in the College of Biological Sciences, and Physiology and Membrane Biology department in the School of Medicine at UC Davis.

Protein blotting home video

 :: Posted by American Biotechnologist on 11-15-2011

We found the amateur home video on protein blotting and western blot analysis posted on teachinhawaii’s YouTube channel. The video is a decent step-by-step demonstration of how to perform protein blotting and western blot analysis. It is appropriate for novice or first-time users. The video shows how to do protein blotting with Bio-Rad’s Mini-Trans Blot or Criterion Protein Blotting Systems. Of course, faster protein blotting can now be perfomed in under 3 minutes with Bio-Rad’s Trans-Blot Turbo Transfer System (as opposed to the 1-2 hours suggested in this video).

We are in the process of collecting protein blotting home videos. If you are aware of an interesting video, please let us know.

Protein blotting guide for novice and advanced users

 :: Posted by American Biotechnologist on 11-15-2011

Protein blotting is a staple technique of most molecular biology and proteomics laboratories. In previous posts, we discussed topics such as semi-dry protein transfer and protein transfer methods, and we even did a multi-part series on western blotting.

Now, we are proud to present you with a 43 page protein blotting guide put together by Bio-Rad Laboratories. The guide is organized into two parts which cover the theory and methods behind protein blotting. You will learn topics such as methods and instrumentation, the difference between various membranes and tranfer buffers, the ins and outs of transfer conditions, detection and imaging and a host of different blotting and detection protocols.

The guide is fairly technical and is appropriate for both novice and advanced users alike.
