Monoclonal ANTI-FLAG® M5 is a mouse antibody that binds to N-terminal Met-FLAG fusion proteins. It is useful for detection of N-terminal Met-FLAG fusion proteins expressed in mammalian and Drosophilae cells.
Method of purification - Protein A
Immunogen
FLAG; peptide sequence DYKDDDDK
Application
Binds the FLAG peptide only when it is located at the amino terminus preceded by a methionine. Binding is not Ca2+-dependent. Useful for detecting cytoplasmically expressed Met-FLAG fusion proteins in mammalian crude cell extracts, but not recommended for fusion proteins expressed in E. coli.
Monoclonal ANTI-FLAG® M5 antibody produced in mouse has been used in western blotting[1] and immunofluorescence.[2]
Physical form
Solution in 10 mM sodium phosphate, 150 mM NaCl, pH 7.4, containing 0.02% sodium azide (w/v)
Preparation Note
Dilute the antibody to 10 mg/mL in Tris buffered saline (TBS): 0.05 M Tris, 0.15 M NaCl, pH 7.4.
Other Notes
Antibody is not calcium dependent.

The transcriptional shift from repression to activation of target genes is crucial for the fidelity of Notch responses through incompletely understood mechanisms that likely involve chromatin-based control. To activate silenced genes, repressive chromatin marks are removed and active marks must
