PGE2-PEG11-biotin is an affinity probe which allows PGE2 to be detected or immobilized using the biotin ligand. The PEG11 moiety serves to separate the biotin linker from PGE2 with a hydrophilic spacer. It is thus a tool to be used in the elucidation of PGE2 actions or interactions in aqueous solutions.WARNING This product is not for human or veterinary use.
