A variant of Vero cell line has been obtained, adapted to the Russian
Eagle's medium with 8% fetal calf serum. The variant is characterized
by intensive cell proliferation, possesses a different content of chro
mosomes, contains no oncogens and contaminants, specifically, Mycoplas
ma. The strain was characterized and certified in accordance with the
WHO requirements. Inoculation (110 ampules) and working (100 ampules)
stocks at the levels of the 170th and 178th passages were placed for s
torage in liquid nitrogen. Vero (B) cell line is sensitive to herpes s
implex virus types 1 and 2, CMV, hepatitis A virus, recombinant variol
ovaccinia strain expressing HbS antigen, etc. The line retains its bio
logical properties from passage 178 to passage 200 and is recommended
for control and preparation of various biomedical agents, including an
tiviral vaccines.
