Funded by a special SARS project
sponsored by the Chinese Ministry
of Science
and
Technology under the National 863
Program, the Institute of Viral Diseases Prevention and
Control, part of the China Diseases Control Center, has for
the first time in the world obtained the genetic engineering
antibodies of human SARS viruses.
It is
reported that researchers initially collected lymphocytes
from the blood of those SARS patients who were in their
convalescent period. They then created the anti - SARS
viruses gene bank by adopting the technique of increasing
the number of the antibody genes. Finally, researchers used
the bacteriophage surface presentation technique to screen
out the genetic engineering monocloning antibodies of the
SARS viruses from the gene bank on the basis of cellular
— cultured SARS virus granules and genetically
restructured SARS virus antigen. These antibodies have
demonstrated their apparent capacity for grouping with SARS
viruses, and some of them have been confirmed as striking at
the surface protein or core protein of the SARS viruses.
Researchers are currently working day and night to evaluate
the capacity of these antibodies to resist the SARS virus.
