EGFP

GFP is a fluorescent protein, consisting of 238 aa (=26,9 kDa), which emits green light after being exposed to blue light. Osamu Shimomura described the first GFP protein derived from Aequorea Victoria in 1962. Its excitation spectrum has two peaks at 396 and 475 nm [Heim et al., 1995]. Due to the second excitation peak at 475 nm, GFP protein is very photo stable [Chalfie et al., 1994].
eGFP (=enhanced GFP) is a potential derivate of GFP, which finds broad usage in mammalian cells. Compared to the wild-type protein, eGFP is a codon optimized GFP and is achieves up to 10fold higher expression rate and up to 30 fold higher bioluminescence

 

Usage and Biology

eGFP is used as a marker gene for detection of transfected cells, e.g. tumor cells.
