General description

The FLAG peptide is used for the competitive elution of amino-terminal, Met-amino-terminal or carboxy-terminal FLAG fusion proteins from the Anti-FLAG M1 or Anti-FLAG M2 antibody (in solution or bound to an agarose gel).


Gently elutes FLAG fusion proteins from ANTI-FLAG® M1 and M2 affinity resins. Usual working concentration is 100 μg/ml. Will not elute 3X FLAG fusion proteins. For this application, use 3X FLAG Peptide, F4799.

Preparation Note

For stock solution, dissolve in TBS (10mM Tris HCL, 150 mM NaCl, pH7.4) to a final concentration of 5 mg/mL.

Acidification of the phagosome is considered to be a major mechanism used by macrophages against bacteria, including Mycobacterium tuberculosis (Mtb). Mtb blocks phagosome acidification, but interferon-gamma (IFN-gamma) restores acidification and confers antimycobacterial activity. Nonetheless, it remains unclear whether acid kills...

Simple low molecular weight (MW) chelates of Gd(3+) such as those currently used in clinical MRI are considered too insensitive for most molecular imaging applications. Here, we evaluated the detection limit (DL) of a molecularly targeted low MW Gd(3+)-based T(1)...

Tyrosyl-DNA phosphodiesterase (TDP1) is a DNA repair enzyme that removes peptide fragments linked through tyrosine to the 3' end of DNA, and can also remove 3'-phosphoglycolates (PGs) formed by free radical-mediated DNA cleavage. To assess whether TDP1 is primarily responsible...

Semi-conservative segregation of nucleosomes to sister chromatids during DNA replication creates gaps that must be filled by new nucleosome assembly. We analyzed the cell-cycle timing of centromeric chromatin assembly in Drosophila, which contains the H3 variant CID (CENP-A in humans)...
