Abstract
Overview
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 a key growth
area 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 has
introduced the Protein Electrophoresis and Western Analysis Dashboard"!,
designed to take a snapshot of the current market landscape with the future
goal of repeating and publishing the study to give Dashboard readers the
ongoing story of how the market is adopting to new products, new competitors
and sales and marketing strategies.
The Protein Electrophoresis and Western Analysis Dashboard"! was developed
from responses to a 36-question survey completed by 462 scientists
predominantly 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 sub-segments:
- Protein capillary electrophoresis systems
- Protein electrophoresis gels or gel casting reagents
- 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 November of 2011, 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 November 14, 2011 and results collected through November 30,
2011. A total of 462 qualified scientists completed the survey. Results based
on the aggregate of collected responses are revealed in this Protein
Electrophoresis and Western Analysis Dashboard.
Respondent Demographics
Respondents from the academic, government and commercial market segments are
well represented, with 25.1% of respondents employed in an industry setting
and 74.9% of respondents employed in academic setting. 66.8% of respondents
are from North America, while 31.8% reside in Europe and 1.4% resides in the
rest of the world.
Junior (Lab Tech, Grad Students, Post-Doctoral Fellow), mid-level (Department
Manager, Project Manager, Scientist, Core Manager, Professor, Instructor, Lab
Manager) and senior (PI, Group Leader, Lab Director, Senior Scientist, CEO)
scientists are well represented in the data set, with the most cited job
titles being Post-Doctoral Fellow/Research Fellow (17.5% of respondents) and
Principal Investigator (14.9%).
A wide variety of scientific areas of specialization is also evident, led by
molecular biology (named by 21.4% of respondents as their primary or secondary
area of expertise) and biochemistry (named by 16.2% of respondents). Cell
biology (12.8%) is the only other application named by more than 10.0% of
respondents.
Small (1-5 scientists), medium (6-20 scientists) and large (>20 scientists)
laboratories are well represented: 35.0% of respondents work in labs where 1
to 5 people perform experiments; 50.9% in labs with 6 to 20 experimenters, and
the remaining 14.1% in labs with greater than 20 bench scientists.
