Aminooxy-PEG4-acid is a PEG linker containing an aminooxy group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The aminooxy group can be used in bioconjugation. It reacts with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended. Aminooxy-PEG4-acid is not stable as a neat compound; it is provided as 1.0M aqueous solution.

Biotin-PEG4-TFP ester is a bifunctional PEG linker with a biotin group and an activated TFP ester. The TFP ester is easily displaced by amines to rapidly form amides under mild conditions, while the biotin group is useful for affinity-based applications such as pull-down assays or for ligating with streptavidin proteins.
