Descrição geral

N-(5-Fluoresceinyl) maleimide, also known as fluorescein-5-maleimide (FM), is a fluorescent derivatization reagent. The pH during the derivatization reaction plays a critical role.

Aplicação

N-(5-Fluoresceinyl) maleimide or fluorescein-5-maleimide is used as a fluorescent biosensor to detect nanoparticles.

N-(5-Fluoresceinyl) maleimide (5-FM) is used to fluorescence label molecules such as proteins and peptides via their thiol groups.

In gram-negative bacteria, transporters belonging to the resistance-nodulation-cell division (RND) superfamily of proteins are responsible for intrinsic multidrug resistance. Haemophilus influenzae, a gram-negative pathogen causing respiratory diseases in humans and animals, constitutively produces the multidrug efflux transporter AcrB (AcrB(HI)). Similar
