His Strep Pqe-trisystem Vector Set - White, Multi-host Expression | His And Strep Dual Tags, T5 And Cmv Promoters

The 32942 His Strep pQE-TriSystem Vector Set by Qiagen is a versatile expression system designed for multi-host expression of His- and Strep-tagged proteins in E. coli, mammalian, and insect cells. This set includes three expression vectorspQE-TriSystem 1, 2, and 3which provide flexibility in cloning and expression, allowing researchers to produce recombinant proteins in different cellular environments.

Each vector contains N-terminal His and Strep tags, enabling dual-affinity purification using Ni-NTA and Strep-Tactin affinity chromatography for high-purity protein isolation. Additionally, these tags facilitate easy detection and functional characterization using anti-His and anti-Strep antibodies. The strong T5 promoter ensures tight control and inducible expression in bacterial systems, while the CMV promoter enables efficient expression in eukaryotic cells.

Ideal for functional studies, structural biology, and protein interaction research, the His Strep pQE-TriSystem Vector Set offers high-yield, high-purity protein production across multiple expression platforms.
