NIH 3T3 cells that were transiently transfected with a Green Fluorescent Protein (GFP) expression vector, then plated and allowed to attach and proliferate. The cells were fixed and labeled with our Alexa Fluor® 594 conjugate of the anti-GFP antibody (Cat. no. A21312). Cells expressing GFP show dual labeling of both GFP (green fluorescence) and the anti-GFP antibody (red fluorescence). In this overlay of fluorescence and differential interference contrast (DIC) micrographs, the GFP-transfected cells exhibit green and red signals that overlap to yield yellow, and DAPI (Cat. no. D1306, D3571, D21490) stains the nuclei with a light-blue fluorescence. In the cells that are not transfected, the DAPI-stained nuclei exhibit a bright blue fluorescence.

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. Green Fluorescent Protein (GFP) has quickly become a powerful research tool for assessing gene expression and subcellular protein distribution in fixed or living cells. GFP is excited by and brightly fluoresces when exposed to UV or blue light. This feature makes it ideal as a marker for use in fluorescence microscopy, cytometry, tagging fusion proteins, and assaying transcriptional regulation from gene promoters in vivo. Numerous GFP variants with enhanced and shifted emission spectra (blue, green, and yellow) have been developed through amino acid substitutions at specific residues.
