[Constructing the reference panel of sera with standard level of IgG-antibodies]

Fundamentals of designing reference panels of sera for effective control of commercial test systems and immunoblotting, intended for detecting antiviral antibodies, have been developed. Reference low-titer panels of anti-IgG antibodies to HIV-a and hepatitis C virus have been designed. A reference panel contains diluted reactive sera with a standard level of IgG antibodies and native sera with undetectable level of antibodies to the major viral antigens from risk group subjects. The reactive sera of a panel contain the whole spectrum of antibodies to all principal viral antigens.
