Fluorescent proteins are ideal for live cell analysis because of their bright colors and intuitive images, which do not require chemical staining and substrates. Fluorescent tags that express proteins can not only label proteins in fixed and living cells, but also different cell types, and even subcellular organelles. If the target protein is fused with a fluorescent protein, intracellular observation of the target protein can be achieved, and it can be used for multicolor labeling and fluorescence resonance energy transfer (FRET). It is also used to visualize the location of proteins with other subcellular structures, study protein-protein colocalization, detect the onset of gene expression from different promoters, and isolate mixed cell populations. Creative Proteomics can provide fluorescent protein fusion services to accelerate your subject progress.
