Expression Vectors

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 in bacterial, mammalian and insect vectors for high quality 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 in mammalian cells 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 bacterial, mammalian, and insect vectors for high quality downstream purification using HIS-Select™ affinity gels.
  
  
• Sigma's pPolh transfer vectors are the first to offer the well-known FLAG tag for expression of FLAG fusions in insect cell systems.
