The Sigma-Aldrich™ Novagen® pET-15b DNA Vector is a high-performance plasmid designed for efficient recombinant protein expression in E. coli using the powerful T7 promoter system. This vector features an N-terminal HIS TAG® sequence, enabling rapid purification of expressed proteins via immobilized metal affinity chromatography (IMAC), along with a thrombin cleavage site for optional removal of the affinity tag after purification.
The pET-15b vector is part of the widely trusted Novagen® pET expression system, known for delivering high-level, tightly regulated expression of recombinant proteins. Supplied as purified plasmid DNA, it also includes an induction control strain, ensuring reliable experimental setup and expression validation.
This vector is ideal for applications in molecular cloning, recombinant protein production, structural biology, enzyme studies, and biotechnology research.
