General description

Sensitive, specific detection of His•Tag fusion proteins
The HIS TAG® Monoclonal Antibody is a mouse monoclonal antibody (IgG1) directed against the HIS TAG® sequence encoded by many of the NOVAGEN® expression vectors as well as many other commercially available vectors. The antibody recognizes five consecutive histidine residues regardless of the surrounding amino acid context. The high affinity (Kd = 5 × 10-8 to 1 × 10-9 M) enables sensitive, specific detection of HIS TAG® fusion proteins at antibody concentrations of 0.1-0.2 g/ml. The HIS TAG® Monoclonal Antibody binds to N-terminal, C-terminal, and internal HIS TAG® sequences. This antibody also detects the recombinant marker bands in the Perfect Protein<TMSYMBOL></TMSYMBOL> and Trail Mix<TMSYMBOL></TMSYMBOL> Western Markers for convenient visualization of accurate internal standards on Western blots*. For lowest background in Western blotting applications, Alkali-soluble Casein is recommended as a blocking agent. The 100-g package size provides enough purified antibody for 1000 mL of working solution.

* Not recommended for HRP-based detection of Trail Mix Western Markers.
