Description:

WARNING: This product is for research use only, not for human or veterinary use.

Biotin-PEG4-TFP ester is a Biotin PEG Linker with a primary amino (-NH2) that forms stable, irreversible amide bonds. 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 (ADCs) and drug delivery methods.
