常规说明Epitope tags provide a method to localize gene products in a variety of cell types, study the topology of proteins and protein complexes, identify associated proteins, and characterize newly identified, low abundance or poorly immunogenic proteins when protein specific antibodies are not available. 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.

ab1170 staining DDDDK in Mouse primary hippocampal neurons by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde and blocked with 5% serum for 1 hour at 25°C. Samples were incubated with primary antibody (1/500 in 1x PBS + 5% Goat serum + 0.1% Triton-X 100) for 24 hours at 4°C. An Alexa Fluor® 555-conjugated Goat anti-chicken IgY polyclonal (1/400) was used as the secondary antibody.
