Prevalence and Characterization of Murine Leukemia Virus Contamination in Human Cell Lines
The multiple sequence alignment was performed using Vector NTI. The multiple sequence file was then imported to showalign of the EMBOSS program collection. The numbers determine the position from the forward primer. Missing nucleotides are represented by a dash and nucleotides different to the consensus sequence are represented by the respective character. * Cell line sequences originating from the NCBI database.
