Example sentences for: htk-

How can you use “htk-” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Polyclonal populations produced by transduction of htk-Tag vectors that were passaged without selection, displayed expression levels equivalent to or higher than LTR-Tag cell lines (Frisa and Jacobberger, unpublished data).

  • Cell lines were created by incorporation of retroviral vectors into the genome and expression of Tag from either the retroviral LTR (considered to be a strong promoter) or the herpes virus thymidine kinase promoter, internal to the viral LTR [ 1 ] . In our established NIH 3T3 cell line, Tag is expressed from the htk promoter at considerably lower levels than from the LTR for a considerable time after transduction [unpublished observations, and [ 11 ] ]. However, when a large number of htk-Tag astrocyte clones were checked 100 days after creation, the expression levels displayed a very large range, and thus we expect that this weak promoter is subject to positional effects on transcription or mutational events that affect gene expression (unpublished data).
