Cell Biosciences Changes Name to ProteinSimple

SANTA CLARA, California, July 18, 2011 -

Cell Biosciences, Inc. today announced that it has changed its
name to ProteinSimple to clearly reflect the Company’s core mission
in protein research.

The Company’s goal is simply to help researchers gain a better
understanding of proteins and their role in disease.
 ProteinSimple’s strategy is to power protein research by
making it simpler and more quantitative, ultimately revealing new
insights into the true nature of proteins.

Over the past 3 years, ProteinSimple has built a unique
portfolio of protein analysis tools including systems for
traditional protein imaging, systems to probe the structure and
purity of protein based therapeutics and systems that provide fresh
insight into protein signaling.  Later this year, the Company
will launch a revolutionary product that is expected to completely
reinvent and automate the Western Blot - the most widely used
technique in protein analysis.

The company expects to generate over $40 million in revenue in
2011, and has grown significantly from $1 million in 2008.
 ProteinSimple has over 170 employees and more than 10,000
systems installed around the world.  In the last 18 months,
the Company has made 4 acquisitions in the protein analysis space
and raised over $60 million in venture capital.  

“We are all very excited about our new ProteinSimple identity,”
commented Tim Harkness, President and CEO of ProteinSimple. “After
a period of tremendous growth and change, we felt it was important
to speak clearly to our customers about our vision and goals.
 ProteinSimple captures our entire value proposition and
culture in a single word.   The employees of ProteinSimple are
fully committed to helping researchers gain a deeper understanding
of proteins and to building a unique protein analysis
pure-play.”
