HPV (human papillomavirus) genotyping detection positive reference as well as preparation method and application thereof

Номер: CN116286982A
Принадлежит:

The invention discloses a positive reference for HPV (human papillomavirus) genotyping detection as well as a preparation method and application of the positive reference. The HPV genotyping detection positive reference product is obtained by co-transfecting a recombinant expression vector containing an HPV whole genome sequence and an FLP recombinase vector into an HEK293T-FRT cell containing a single copy FRT site sequence, and then performing drug screening and single cell cloning screening, and a monoclonal stably transfected cell line containing the HPV whole genome sequence is obtained. The sample is the positive reference for HPV genotyping detection. The genetic background of the positive reference is stable, is close to that of a clinical sample, can be stably stored, is superior to a plasmid product in performance and stability, and cannot cause detection deviation due to the problems of concentration deviation and gene structure complexity. In addition, the reference product ...
