To investigate whether tick-borne encephalitis viruses (TBEVs) are present in South Korea, Korean ixodid ticks were tested for TBEV RNA. Ticks (n = 2460) were collected from wild and domestic animals or by flagging at forest and grassland in 12 regions of five provinces in 2005-06. Four species in two genera were identified, yielding 197 sample pools (1-20(More)
Succinylated collagen was synthesized by the reaction of collagen with succinic anhydride under basic conditions for one hour. Using the matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) technique, the reaction products were directly identified without multi-step separation processes. MALDI-MS monitored the reaction more accurately than(More)
