Description:

Rhodamine fluorescent labeled polyethylene glycol, one of fluorescent labeled PEG derivatives. Rhodamine B-PEG sulfhydryl (RB-PEG-SH) can be used to modify proteins, peptides and other materials or small molecules. Maleimide imide and mercapto (- SH) are easy to form stable thioether bond at PH6.5-7.5. Mercaptan groups have high affinity for gold surface and are widely used to modify gold nanoparticles or gold films. (RB-PEG) 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.

The compounds on which fluorescent labeling relies are called fluorescent substances. Fluorescent substances refer to compounds with the chemical structure of a common ring double bond system. When exposed to ultraviolet light or blue violet light, they can be excited into the excited state, and when recovered from the excited state, they emit fluorescence. Fluorescent labeling technology refers to the use of fluorescent substances to covalently bind or physically adsorb to a certain functional group of the molecule being studied, and use its fluorescence characteristics to provide information about the studied object. The advantages of fluorescence labeling, such as no radioactive contamination and easy operation, have led to the increasingly widespread application of fluorescence labeling in many research fields.
