Effects of mutations on herpes simplex virus 1 thymidine kinase functionality: an in vitro assay based on detection of monophosphate forms of acyclovir and thymidine using HPLC/DAD.

Abstract excerpt

Discrimination between the mutations responsible for drug resistance and those of UL23 TK gene polymorphism can be difficult. A non-isotopic method has been developed to assess TK functionality by measuring monophosphate forms of both acyclovir (ACV) and thymidine using HPLC/DAD. Phenotypes of TKs could thus be characterized as TK altered (P84L, A189V, L227F), TK deficient (G200S, L291P) or TK partial (R163H). A...
