Jivan and ArrayIt Develop Splice Variant Microarray for Total Blood

Berkeley and Sunnyvale, CA (July 6, 2004) -- Jivan Biologics, Inc., a privately held company, and ArrayIt Life Sciences Division of TeleChem International, Inc., today announced a partnership to develop Hematome™, a splice variant microarray for hybridization with total blood.

"ArrayIt's pioneering chemistry expertise and exacting manufacturing standards bring high reproducibility and confidence to the Hematome™ splice variant microarray," said Subha Srinivasan, Ph.D., CEO of Jivan Biologics.

"With Jivan's patent-pending oligonucleotide design, the Hematome™ microarray will enable scientists to measure RNA splicing regulation of genes expressed in total blood with unique precision," said Todd Martinksy, Founder and Executive Vice President of TeleChem International, Inc.

Hematome™ is currently available in a test version with a carefully selected set of genes and splice variants expressed in human total blood. The full version will include probes for alternatively spliced sites in thousands of genes in total blood, providing an unprecedented and powerful test for biomarkers, diagnostics and patient subtyping.
