Description

Mouse Monoclonal Antibody

Store vial at 4°C prior to restoration. For extended storage aliquot contents and freeze at -20°C or below. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4°C as an undiluted liquid. Dilute only prior to immediate use. This antibody is directed against the FLAGTM epitope tag and is useful in determining its presence in over expressed proteins in various assays. The antibody recognizes the FLAGTM epitope tag (Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys) fused to either the amino- or carboxy- termini of targeted proteins in transfected or transformed cells.

DYKDDDDK Tag (FLAG™ tag, FLAG octapeptide) is a polypeptide protein tag that can be added to a protein using recombinant DNA technology. The FLAG tag structure has been optimized for compatibility with the proteins it is attached to, in that it is more hydrophilic than other common epitope tags and therefore less likely to denature or inactivate proteins to which it is appended. A FLAG tag can be used in many different assays that require recognition by an antibody. If there is no antibody against the studied protein, adding a FLAG tag to this protein allows one to follow the protein with an antibody against the FLAG sequence. Examples are cellular localization studies by immunofluorescence or detection by SDS PAGE protein electrophoresis. Tagging with xxxDDDDK may be done at the N-terminus, N-terminus preceded by a methionine residue, C-terminus, and in internal positions of the target protein. The small size of the epitope tag and its high hydrophilicity tend to decrease the possibility of interference with protein expression, proteolytic maturation, antigenicity and function. The enterokinase cleavage site allows it to be completely removed from the purified fusion proteins. FLAG is a trademark of Sigma-Aldrich Biotechnology LP
