LifeMap Sciences Adds Products Through Partnership with ProSpec-Tany TechnoGene

- BioTime Subsidiary offers 100 select recombinant proteins in its BioReagents Portal -

ALAMEDA, Calif.--(BUSINESS WIRE)--April 10, 2013--LifeMap Sciences, Inc., a subsidiary of BioTime, Inc. (NYSE MKT: BTX), announced today that it is now offering 100 selected ProSpec-Tany TechnoGene (ProSpec) manufactured recombinant proteins related to stem cell research in its recently launched LifeMap BioReagents™ portal (http://bioreagents.lifemapsc.com) to researchers worldwide. ProSpec’s innovative recombinant proteins, including growth factors, signaling molecules, differentiation factors, hormones, cytokines and chemokines will complement the current BioTime research product lines available via LifeMap BioReagents™, including BioTime’s PureStem™ human progenitor cell lines, PureStem™ packages, clinical and research grade human embryonic stem cell lines (hES), ESpan™ growth media for progenitor cell lines, and cell differentiation media.

The addition of ProSpec products reflects LifeMap Sciences’ execution of its strategy to market a growing catalog of research products to aid scientists in a variety of fields, including stem cell research, developmental biology, mechanisms of various human diseases and drug and therapeutic discovery.

LifeMap Sciences holds an exclusive, worldwide license to market GeneCards^® (www.genecards.org), the human gene compendium, and MalaCards (www.malacards.org), a database with nearly 17,000 human disease entries, from Yeda Research and Development Company Ltd., the commercial arm of the Weizmann Institute of Science. Additionally, it has recently launched version 1.1 of LifeMap Discovery™, a comprehensive embryonic development and stem cell compendium, a database owned and developed by LifeMap Sciences. According to Google Analytics, the sites have generated more than 2,000,000 unique visitors with more than 13,000,000 page views in the past 12 months. Links from LifeMap Discovery™ to BioTime and ProSpec manufactured products in the LifeMap BioReagents™ portal will enable researchers who access the database to become familiar with, and purchase, products that relate directly to the types of cells, genes or diseases that they are studying and can assist them in various research projects.

“We are pleased to meet this significant milestone in our e-Commerce strategy,” stated Yaron Guan-Golan, Head of Marketing at LifeMap Sciences. “Our growing LifeMap Discovery™ user base will now be able to identify high quality recombinant proteins that can be helpful for their research and purchase them via LifeMap BioReagents™. This will increase LifeMap BioReagents™ brand awareness and the quality of our offering to the global biomedical research community.”
