To facilitate your research with respect to successful gene-expression and protein production, abm offers an entire repertoire of >26,000 genes for human and >20,000 genes for mouse and rat in an array of strategically designed expression vectors.


Key features of abm's protein expression vectors include:

  • The option for expression in either a prokaryotic (E. coli; T7 promoter based) or a eukaryotic (mammalian cell; CMV promoter based) system.
  • A choice of 5 tags (His, HA, MBP, GST and D-tag; some in combination) with both N-terminal and C-terminal options for a His tag.
  • A near complete library of human genes to choose from.

The below table can be used as a quick reference guide for determining what our different tags can offer:


Tag Name Description Size (kDa) Cleavable
C-His A single C-terminal 6X-Histidine tag. 0.84 No
N-His A single N-terminal 6X-Histidine tag. 2.3 Yes (with thrombin)
C-HA A single C-terminal Hemagglutinin tag. 1.1 No
His-MBP Dual N-terminal tag; 6X Histidine followed by Maltose Binding Protein. 43 Yes (with TEV)
His-GST Dual N-terminal tag; 6X Histidine followed by Glutathione-S-Transferase Protein. 27.9 Yes (with TEV)
N-D-C-HA Dual tags; N-terminal 3X D-tag and C-terminal Hemagglutinin tag. N: 3X FLAG: 3.5
C: HA: 1.1
N: Yes (with TEV)
C: No
N-D-C-His Dual tags; N-terminal 3X D-tag and C-terminal 6X-Histidine tag. N: 3X FLAG: 3.5
C: His: 0.84
N: Yes (with TEV)
C: No
