Description
PLLA(4k)-PEG(1k)-RhB is a PEG linker that consists of a poly-L-lysine (PLLA) segment with a molecular weight of 4 kDa, a polyethylene glycol (PEG) segment with a molecular weight of 1 kDa, and a rhodamine B (RhB) dye attached at one end.
Applications
PLLA(4k)-PEG(1k)-RhB prepares biomaterials with fluorescent labeling function for cell imaging, tissue imaging and other studies, and tracks the distribution and metabolism of the materials in the organism in real time.
