China Develops Gene Chip

After five year's research, the State Research Center for Bio-Tech Engineering and Beijing Jin Di Ke BioTech Institute have established a Genome-Specific Probe Database for viruses already known to human beings and some other pathogenic organisms, and developed a high-density gene chip able to detect several hundred kinds of pathogenic organisms.

The system has been developed to be able to detect swiftly pathogenic organisms that are causing troubles and quickly identify the unidentified viruses, thereby laying an important base for a pathogenic organism monitoring and control system to be established nationwide. Scientists have established a series of gene chips with varying functions, including the ability to detect respiratory and intestinal viruses and pathogenic organisms in the air.

Five years ago, Chinese scientists began to attempt to establish a system for the monitoring and control of pathogenic organisms. "The establishment of a complete database specific-virus test probe, including over 3,000 specific probes for over 300 kinds of viruses related to human diseases, can help detect over 300 kinds of pathogens at one time. The daily production of chips can reach 100 to 200", said Shu Yuelong, vice president of Beijing Jin Di Ke BioTech Institute.
