    Product Information

    Product Description

    This Cell Signaling Technology® antibody retains the antigen-binding Fab regions of the original parent host sequence from which it is engineered. This antibody is expected to exhibit the same species cross-reactivity as His-Tag (D3I1O) XP® Rabbit mAb #12698.

    Product Usage Information

    Application Dilution
    Immunofluorescence (Immunocytochemistry) 1:200 - 1:800

    Storage

    Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    His-Tag (D3I1O) XP® Feline Chimeric mAb recognizes 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

    This recombinant chimeric antibody is engineered from His-Tag (D3I1O) XP® Rabbit mAb #12698 according to animal-free protocols. The chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody but contains a feline-derived Fc domain. When multiplexing, Fc-directed rabbit secondaries are required to detect rabbit-host primary antibodies.

    The parent antibody, His-Tag (D3I1O) XP® Rabbit mAb #12698 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).
