Recombinant Jellyfish (Aequorea victoria) green fluorescent protein, full length with C-terminal His-tag, MW= 29.9 kDa, expressed in an E. coli expression system. GFP absorbs light at 395 and 470 nm, emits green fluorescence at 509 nm.
Background
Green fluorescent protein has been engineered to produce a vast number of variously colored mutants, fusion proteins, and biosensors. Fluorescent proteins and its mutated allelic forms, blue, cyan and yellow have become a useful and ubiquitous tool for making chimeric proteins, where they function as a fluorescent protein tag. Typically they tolerate N- and C-terminal fusion to a broad variety of proteins. They have been expressed in most known cell types and are used as a noninvasive fluorescent marker in living cells and organisms. They enable a wide range of applications where they have functioned as a cell lineage tracer, reporter of gene expression, or as a measure of protein-protein interactions.
