Hi, Netters Does anybody know the company where I could get a biotin-lys-tRNA? Although I want to express a protein in vitro with a transcription and translation coupled system, Amersham sells only a translation system in vitro. Thanks in advance. -- Tetuya Ookura Internet : ookura at nfri.affrc.go.jp Tel. +81-298-38-8051 Fax +81-298-38-7996
