Cell Biosciences Delivers Next Generation System to Stanford University

Back to News

PALO ALTO, CA, January 6, 2009 - Cell Biosciences, Inc., a provider of nanoproteomic analysis systems to life science researchers, today announced the placement of a next-generation protein analysis system prototype, the Cell Biosciences CB1000, at the Stanford University School of Medicine. David Hirschberg, Ph.D., Director of the Human Immune Monitoring Center (HIMC) at Stanford, will analyze oncoprotein activation in a variety of human clinical samples on the prototype CB1000 and assist Cell Biosciences in optimizing the system's final feature set.

The Cell Biosciences CB1000 prototype is an ultrasensitive nanofluidic immunoassay system designed to analyze extremely small biological samples. Because of the system's high detection sensitivity, cell signaling proteins can be measured reproducibly in as few as 25 cells. The CB1000 system will feature a significantly streamlined workflow, higher sample throughput, a much smaller footprint, and a host of performance improvements relative to previous systems. The CB1000 is scheduled for commercial release in mid-2009.

"The current Cell Biosciences platform is used heavily by multiple users at HIMC," said Dr. Hirschberg. "We are pleased to see the rapid advancement of Cell Biosciences' technology, and look forward to working with the new prototype system."

"To produce world-class instrumentation systems, it is critical to work closely with world-class researchers," explained Bob Gavin, Vice President of Engineering at Cell Biosciences. "Input from the Stanford team will be translated directly into improved product design. We feel very fortunate to be able to leverage Dr. Hirschberg's deep scientific knowledge."
