RT Journal Article SR Electronic(1) A1 Holtermann, O. A.YR 1969 T1 Amino Acid Requirement for the Propagation of Vaccinia Virus in Earle’s L Cells JF Journal of General Virology, VO 4 IS 4 SP 585 OP 591 DO https://doi.org/10.1099/0022-1317-4-4-585 PB Microbiology Society, SN 1465-2099, AB Summary Using Earle’s L cells, the amino acid requirement for the propagation of vaccinia virus was found to coincide with the amino acids found by Eagle (Eagle, 1955; Eagle et al. 1956) to be essential for the L cells themselves. There was no evidence that vaccinia virus particles harbour enzymes involved in amino acid synthesis., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-4-4-585
