    Product Information

    Product Usage Information

    This product is the carrier free version of product #12698. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.

    This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.

    BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.

    Formulation

    Supplied in 1X PBS (10 mM Na2HPO4, 3 mM KCl, 2 mM KH2PO4, and 140 mM NaCl (pH 7.8)). BSA and Azide Free.

    For standard formulation of this product see product #12698

    Storage

    Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.

    Specificity / Sensitivity

    His-Tag (D3I1O) Rabbit Monoclonal Antibody (BSA and Azide Free) detects recombinant proteins containing the 6xHis epitope tag. This antibody recognizes the 6xHis-tag fused to either the amino or carboxy terminus of targeted proteins in transfected cells. This antibody detects exogenously expressed 6xHis-tagged proteins in cells expressed under a CMV promoter. Expression under other promoters has not been evaluated.

    Species Reactivity:

    All Species Expected

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues of the 6xHis epitope tag.

    Background

    Epitope tags are useful for the labeling and detection of proteins using immunoblotting, immunoprecipitation, and immunostaining techniques. Because of their small size, they are unlikely to affect the tagged protein’s biochemical properties.
    A variety of plasmids contain DNA that encodes an amino-terminal tag consisting of six histidine (6xHis) residues followed by an extended multiple cloning site. The 6xHis tag on the expressed recombinant proteins allows for efficient coupling to Ni2+ affinity resins and purification by single step chromatography (1).

    As is the case with other protein tag systems (2), this polyhistidine tag can often be cleaved at sites recognized by proteases such as thrombin and enterokinases to isolate the protein of interest (1).
