Description:

Rhodamine polyethylene glycol 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 at pH 7-8.5. The maximum absorption wavelength of rhodamine (RB -) is 570 nm, and the emission wavelength is about 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 the non-specific binding of charged molecules on modified surfaces.
