The green fluorescent protein (GFP) is a protein that exhibits green fluorescence when exposed to light in the blue to ultraviolet range. [2] [3] The label GFP traditionally refers to the protein first isolated from the jellyfish Aequorea victoria and is sometimes called avGFP.

This review is an attempt to characterize the main color groups of GFP-like proteins, describe their structure and mechanisms of chromophore formation, systemize data on their conformational stability and summarize the main trends of their utilization as markers and biosensors in cell and molecular biology.

A brief personal perspective is provided for green fluorescent protein (GFP), covering the period 1994–2011. The topics discussed are primarily those in which my research group has made a contribution and include structure and function of the GFP ...

Sep 14, 2022 · Biologists use GFP as a marker protein. GFP can attach to and mark another protein with fluorescence, enabling scientists to see the presence of the particular protein in an organic structure. Gfp refers to the gene that produces green fluorescent protein.

Invitrogen Green Fluorescent Protein (GFP) is a useful expression label in the blue channel for flow cytometry and imaging applications. GFP can be excited by the 488 nm laser line and is optimally detected at 510 nm.

Mar 1, 2022 · Green fluorescent protein (GFP), a fluorescent marker extracted from Aequorea victoria, has been a prominent tool for protein visualisation in modern biomedical research. When properly folded, it emits green fluorescence upon UV illumination.

GFP has become well established as a marker of gene expression and protein targeting in intact cells and organisms. Mutagenesis and engineering of GFP into chimeric proteins are opening new vistas in physiological indicators, biosensors, and photochemical memories. CONTENTS.

In this article and the accompanying poster, we will describe some of the general properties of FPs that are important to their function. We will also provide examples of successful mutagenesis that has been used to improve the use of these proteins for live-cell imaging, particularly for mammalian studies.

Cell marking/selection: Expression constructs like plasmids often include GFP as a marker to help identify which cells have successfully taken up the plasmid. This can serve as an alternative to antibiotic selection.

Cell Marking and Cell Selection - With such expression constructs like plasmids, GFP is included as a marker. This helps in identifying which of the cells have successfully taken up the plasmid.
