Biology
Traditionally isolated from the jellyfish Aequorea victoria, the green fluorescent protein (GFP) has become an important marker for gene expression [1]. However, due to the relatively lower sensitivity of wild-type GFP compared to standard reporter proteins, many different mutants of GFP have been engineered. Thereby, mutations introduced in chromophore of GFP significantly improved its detection and made the protein 35 times brighter than wild-type GFP. The modified fluorescent protein, also known as enhanced GFP (eGFP), appeared to be more sensitive compared to initial detection results [2].
