Originally, the FRAP technique was intended for use as a means to characterize the mobility of individual lipid molecules within a cell membrane. While providing great utility in this role, current research leans more toward investigation of artificial lipid membranes. Supported by hydrophilic or hydrophobic substrates (to produce lipid bilayers or monolayers respectively) and incorporating membrane proteins, these biomimetic structures are potentially useful as analytical devices for … WebIn order to adapt the jellyfish fluorescent proteins for use in mammalian systems, several basic amino acid modifications of the wild-type green fluorescent protein were undertaken and are now found in all commonly used variants.
