What is a His tag antibody?

What is a His tag antibody?

His-tag is a series of six to nine histidine residues fused to either the carboxyl or amino terminus of a recombinant protein. His-tag antibodies provide a dependable method for the detection and purification of tagged target proteins without a protein-specific antibody or probe.

What is 6x His tag?

The 6xHis tag, also known as polyhistidine tag, His6 tag and/or hexa histidine tag, is an amino acid motif consisting of at least 6 histidine residues fused to the carboxyl (C-) or amino (N-) terminus of a target protein in transfected cells.

What is anti His antibody?

Anti-His Tag Antibody. PolyHistidine Tags (His Tags) are a popular addition to recombinant proteins to facilitate protein purification and detection. His Tags are commonly used in preference to other tags due to the availability of inexpensive purification resins such as NiNTA.

What is anti histidine?

Anti-histidine antibodies can be used to monitor the progress of purification and the fraction containing the recombinant protein by western blotting, and to verify that no proteolytic degradation of the recombinant protein is taking place.

What does a Polyhistidine tag do?

The polyhistidine-tag can be successfully used for the immobilization of proteins on a surface such as on a nickel- or cobalt-coated microtiter plate or on a protein array.

Is his-tag immunogenic?

Although the His-tag is a short and poorly immunogenic sequence, its attachment to a recombinant protein might mask immunologically important epitopes and reduce the potential immune response towards the target antigen, a potential impact that requires experimental evaluation [22].

How do you install a histidine tag?

Adding polyhistidine tags. (A) The His-tag is added by inserting the DNA encoding a protein of interest in a vector that has the tag ready to fuse at the C-terminus. (B) The His-tag is added using primers containing the tag, after a PCR reaction the tag gets fused to the N-terminus of the gene.
