摘要：
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 reliable link between HSV UL23 TK mutations and ACV resistance is necessary for developing a powerful genotyping tool to detect ACV resistance quickly in clinical samples. (c) 2012 Elsevier B.V.
