L5_A488_DYKDDDDK_ICC_Antibody_032918
HeLa cells non-transfected (A) or transfected with DYKDDDDK Tag fused protein (B and C) were fixed with 4% paraformaldehyde (PFA) for 10 minutes, permeabilized with 0.5% Triton X-100 for 3 minutes, and blocked with 5% FBS for 60 minutes. Then the cells were intracellularly stained overnight at 4 degrees with 1: 250 diluted (2 µg/ml, Figure A and B) and 1: 1000 diluted (0.5 µg/ml) Alexa Fluor® 488 anti- DYKDDDDK Tag (Figure C, green). Nuclei were counterstained with DAPI (blue). The image was captured with a 40X objective.

Description

The DYKDDDDK tag, commonly referred to as Sigma®'s FLAG® Tag, is often used as a protein modification in order to simplify the labeling and detection of proteins.This unique amino acid sequence allows for specific antibody detection in western blotting, immunoprecipitation, and immunostaining techniques.Due to the short sequence, this modification is not likely to affect the structure or function of the modified proteins.
