Rhodamine polyethylene glycol active esterApplication Introduction:

Rhodamine PEG active ester (RB-PEG-NHS) can be used to modify proteins, peptides, and other active group materials or small molecules. Active esters (- NHS) are PEG derivatives that can react with amino groups (- NH2) to form stable amide bonds with primary amine groups at pH 7-8.5. Rhodamine B (RB -) has a maximum absorption wavelength of 570 nm and an emission wavelength of approximately 595 nm. Rhodamine B can easily track pink and red fluorescence. Polyethylene glycol (PEG -) can increase solubility and stability. Reducing the immunogenicity of peptides and proteins can also inhibit non-specific binding of charged molecules on modified surfaces.
