Protein Simple: An Automated Western Blotting system
Information provided by John Froehlich
Western blotting is an important technique used in cell and molecular biology. By using a western blot, researchers are able to identify specific proteins from a complex mixture of proteins extracted from cells. The technique uses three elements to accomplish this task: (1) separation by size, (2) transfer to a solid support, and (3) marking target protein using a proper primary and secondary antibody to visualize. Unfortunately, traditional western blotting, in general, is tedious to operate, prone to variability and is not very amenable to high throughput strategies. To overcome these shortcomings, the Center for Advanced Algal and Plant Phenotyping (CAAPP) has purchased an automated western blot system, termed Wes™ (Made by Protein Simple: http://www.proteinsimple.com). Specifically, Wes™ (see figure below) that automates the entire western blotting procedure and has several significant advantages over conventional western blotting such as:
- All the manual steps are removed thus saving valuable time
- Fully analyzed results are ready in just 3-5 hours
- Automating the process removes variability, so results are more reproducible run to run, between users and over time.
- Since Wes™ doesn’t do a blotting step, protein transfer inconsistencies are eliminated, giving you more quantitative data.
- Western protocols can be standardized across users and multiple, global locations
The Wes™ will hopefully be up and running in Room 110 (Plant Biology Building) by mid December or early January 2015. Finally, procedures to use the Wes™ will be established and in place once the Wes™ is up and running thus allowing researchers to incorporate this new technology into their research plans.
