What is GFP and BFP?

Green Fluorescent Protein (GFP)

GFP, or Green Fluorescent Protein, is a protein that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range. Originally isolated from the jellyfish Aequorea victoria, GFP has become an invaluable tool in molecular biology, biotechnology, and biochemistry for its use as a fluorescent marker. This protein has revolutionized the way researchers study cellular processes and molecular interactions within living cells, allowing for real-time visualization of gene expression, protein localization, and intracellular signaling pathways.

Blue Fluorescent Protein (BFP)

BFP, or Blue Fluorescent Protein, is a variant of the green fluorescent protein that has been genetically engineered to emit blue light. BFPs were developed to expand the color palette of fluorescent proteins available for scientific research, enabling the simultaneous visualization of multiple proteins or cellular components in different colors. This allows for more complex studies of cellular dynamics and interactions. Like GFP, BFPs are used extensively in molecular biology, cell biology, and biochemistry for tagging and tracking proteins, studying gene expression, and visualizing cellular processes.
