BDP FL-PEG4-Mal is a BDP FL linker containing a maleimide group, which selectively reacts with free thiol, sulfhydryl, or mercapto group via Michael addition to form a stable carbon sulfur bond. BDP FL-PEG4-Mal is a bright and photostable thiol-reactive dye for protein labeling, peptide modification, and can replace fluorescein for microscopy. The hydrophilic PEG spacer arm increases water solubility, membrane permability, and conjugation efficiency. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
