Includes: 200ng of linearized, topoisomerase I-activated Champion pET vector; sterile water; dNTPs; 10X PCR Buffer; salt solution; control template and primers; primers for sequencing or PCR screening; and an expression control. The TOP10 box contains twenty-one 50μL aliquots of chemically competent E. coli, S.O.C. medium, and a control plasmid.
Description
- Based on T7 expression vectors originally developed by Studier and colleagues, high-level expression is achieved because T7 RNA polymerase is more processive than native E. coliRNA polymerase and is dedicated to transcription of gene of interest
- Protein production is further enhanced in system by expression strain BL21 StarE. coli, which significantly improves stability of mRNA transcripts and increases protein expression up to ten-fold
- Simplified, efficient Directional TOPO cloning allows to quickly enter ChampionpET Expression vector
- Features linearized, topoisomerase I-activated ChampionpET expression vectors for five-minute directional cloning
- Directional TOPO Cloning technology facilitates gene expression becausa proofreading enzyme is used for PCR, resulting in fewer errors in cloned genes
- Greater than 90% of clones are in correct orientation for gene expression, reducing time spent on colony screening
