Introduction

Protein electrophoresis is a commonly used technique to separate proteins, and is often followed by in-gel staining and/or western analysis to detect the proteins of interest. With a wide variety of applications in proteomics, ranging from protein characterization to protein quantification and applications in other areas such as clinical diagnostics and verification of in vivo and in vitro protein expression, protein electrophoresis and western analysis products are widely used by scientists in academia and industry. Protein electrophoresis and western analysis products represent key opportunities in the life sciences industry as life science suppliers continue improving products and services in this market.

In order to dive more deeply into the characteristics and dynamics of the market for protein electrophoresis and western analysis, Percepta introduced the Protein Electrophoresis and Western Analysis Dashboard™ (PEW) in January 2012 (data for which was collected in December 2011), designed to take a snapshot of the market landscape with the future goal of repeating and publishing the study to give Dashboard readers the ongoing story of how the market is adapting to new products, new competitors and sales and marketing strategies.

The 2013 Protein Electrophoresis and Western Analysis Dashboard™ was developed from responses to a 44-question survey completed by 447 scientists located in North America and Europe. This Dashboard reveals key market indicators for the protein electrophoresis and western analysis market as a whole as well as for the following techniques representing market sub-segments:

• Protein capillary electrophoresis systems
• Precast protein electrophoresis gels
• Reagents for pour your own protein electrophoresis gels
• Protein standards
• Protein stains
• Western blotting membranes
• Western detection reagents

Certain market information (share of mentions) is also included on the following electrophoresis apparatus segments:

• Protein electrophoresis apparatus
• Western transfer device
• Electrophoresis power supplies

This report is focused on the use of protein electrophoresis and western analysis products in life science research market.

Survey Methodology

In October of 2013, Percepta fielded the Protein Electrophoresis and Western Analysis Survey to a subset of the company’s panel of life scientists. Individuals were invited by e-mail blast to click through to a webpage at perceptabioanalytix.com where the survey was hosted. Invitations were delivered on October 14, 2013 and results collected through October 21, 2013.  A total of 447 scientists completed the survey. Results are based on the aggregate of collected responses.
