Bio-Rad Launches Syphilis Igg Kit for Use on its Bioplex 2200 System

Bio-Rad Laboratories, Inc. (AMEX: BIO and BIOb), a multinational manufacturer and distributor of life science research and clinical diagnostics products, announced today that it has launched a test for syphilis for use on its BioPlex^® 2200 system, a revolutionary diagnostic platform that employs multiplexing technology to analyze multiple disease markers from a single patient sample.

The BioPlex 2200 Syphilis IgG kit simultaneously detects three of the most clinically relevant Treponema pallidum (the bacteria that causes syphilis) antibodies using recombinant proteins in a multiplex format. The Syphilis IgG kit can be used as a diagnostic clinical screen for past or present syphilis infection or as a diagnostic confirmatory test.

"The release of the Syphilis IgG kit is another example of Bio-Rad's continued commitment to providing valuable tools that enable laboratories to improve testing methods, maximize efficiencies, and lower costs," said John Goetz, Bio-Rad Vice President and Group Manager Clinical Diagnostics.

The BioPlex 2200 system is the first and only fully-automated, random access multiplex testing system that provides clinical laboratories with the technology to rapidly process or "multiplex" multiple individual tests, which are traditionally processed separately, using a single small volume patient sample.
