The pIEx vectors are designed for cloning and high-level expression of proteins in transiently transfected Spodoptera-derived insect cells. Transcription is driven by the AcNPV-derived hr5 enhancer and immediate early promoter, IE1. pIEx-1 contains N-terminal His•Tag and S•Tag coding sequences, and a C-terminal HSV•Tag coding sequence. N-terminal vector encoded sequences can be completely removed by cloning into the PshA I site and cleaving the fusion protein with enterokinase. pIEx-1 is also available as an Ek/LIC vector. The Ek/LIC vector is prepared for rapid directional cloning of PCR-amplified DNA. Using specifically designed primers for amplification, inserts can be efficiently cloned without the need for restriction enzyme digestion or ligation. For sequencing or PCR of recombinants in pIEx-1, refer to the table below to choose the appropriate primers.，官网链接：https://www.sigmaaldrich.cn/product/mm/71241m 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
