Biotin-PEG3-acid is a heterobiofunctional biotin PEG analogue containing a carboxylic acid group. The hydrophilic PEG spacer arm imparts water solubility that is transferred to the biotinylated molecule. PEG Linkers may be useful in the development of antibody drug conjugates and drug delivery methods.
