Green fluorescent protein (eGFP)


Purified Enhanced Green Fluorescent Protein (eGFP)

Green Fluorescent Protein is a natural, autofluorescent protein from the jellyfish Aequorea victoria that is frequently used as a control protein in method development and calibration. Enhanced GFP (eGFP) is a mutated GFP with enhanced fluorescence signal and a slightly shifted excitation spectrum. Cube Biotech offers three variants of eGFP with His, GST, Rho1D4, and DYKDDDDK (also known as FLAG) tags. Please contact us for bulk inquiries, academic projects or collaboration ideas.
