FIELD: biotechnology.
SUBSTANCE: described is a method for indirect determination of concentration of A-antigen of the industrial strain "VGNKI" of the causative agent of canine infectious hepatitis in raw material for cultural vaccines according to the cycle of quantitative assessment during amplification of the target region of the orf25-gene.
EFFECT: main advantages of the proposed invention are reduction of time for analysis of industrial raw material for production of cultural vaccines against CAV-1 by determining the concentration of the A-antigen of the strain "VGNKI" CAV-1 virus up to 3 hours (16 times faster than the prototype); elimination of contamination probability; high analytical, diagnostic sensitivity and specificity of the analysis; elimination of subjectivity factor of obtained results due to use of instrumentation for detection of results; increased reliability of the analysis due to the establishment of the relationship between the concentration of the A-antigen of the strain "VGNKI" CAV-1 and the cycle of quantitative assessment of the amplicons of the target region of the orf25-gene, presented in form of quadratic function with high values of accuracy of approximation and efficiency of amplification reaction.
