Santa Clara, CA, 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.”
