Expression Vectors

DNA vectors are the foundation of recombinant protein expression. Sigma now offers such vectors for bacterial and mammalian expression. Featured are a variety of tags, promoters and elements for secretion, transient, stable and bicistronic expression.

• Our exclusive FLAG® and 3xFLAG® tags are provided in N-terminal, C-terminal, and dual tag configurations for detection and purification using ANTI-FLAG® antibodies, resins, and 96-well plates.
• Unique BICEP™ vectors contain an optimized EMCV IRES for high levels of bicistronic expression for optimal maintenance of stable cell lines and multi-gene expression.
• The new MAT™ (Metal Affinity Tag) has been incorporated in many of our popular vectors for high quality purification using HIS-Select™ affinity gels.

Whatever your protein and expression needs, Sigma has the vector for you. Click on the links for information on each vector.
