Special reagents
We provide reagents for affinity labeling (Biotins) and for conjugation chemistry (maleimides, thiols).
Biotin PEG Amine
Biotin PEG Thiol
Biotin PEG Acid
Maleimidopropionyl-PEG NHS Ester
Biotin PEG
The biotin groups serve as an affinity label towa*** the proteins ***idin and strept***idin. PEG attached to the biotin gives an extended spacer arm that permits the biotin to reach into the binding pocket of the protein. The PEG moiety also increases solubility of Biotin-PEG conjugates c***iderably.
Biotin PEG Amine
Biotin PEG Thiol
Biotin PEG Acid
Maleimide PEG
The maleimide group is commonly used for conjugation reacti*** in pair with a thiol.
Maleimidopropionyl-PEG NHS Ester
PEG THIOL/DISULFIDE
The thiol group is a strong nucleophile and is used in conjugation reacti***. The reaction with the maleimide is frequently used for coupling chemistry.
mPEG Disulfide
mPEG Thiol
PEG Acid Disulfide
PEG NHS Ester Disulfide
PEG Thiol
PEG Thiol Acid
Biotin PEG Thiol
Thiol Acid
Thiol acids prove utility in formation of SAM, where the acidic function may be modified after self assembly. The reagents can be combined with mPEG thiol for dilution of functional groups on the modified surface. Also see our pre-activated NHS ester for similar applicati***.
PEG Acid Disulfide
PEG NHS Ester Disulfide
PEG Thiol Acid
PEG Thiol
mPEG and PEG thiols and disulfides are provided in various lengths. Please inquire for other -OH and -OCH3 terminated derivatives
mPEG Thiol
PEG Thiol
PEG
The products are obtained from polydisperse polyethylene glycol, which is fractionated into single oligomer quality. Product specification is set to > 95% oligomer integrity, but the actual purity is usually 97-99%.
Octaethylene Glycol
Dodecaethylene Glycol
PEG-28
mPEG
Methoxy-PEG or mPEG is a PEG chain h***ing one functional group blocked with a methyl group. mPEG and mPEG derivatives are therefore useful for modification of compounds where cross-linking should be ***oided.
mPEG Disulfide
mPEG Thiol
mPEG-7
mPEG Acid
mPEG-11
mPEG-17
mPEG derivative
The methoxy-PEG, or mPEG, is modifed on its free end to provide a range of useful derivatives. The absence of bis-functional impurities is ensured by chromatographic purification.
mPEG Disulfide
mPEG Thiol
mPEG Acid
PEG AMINE
The amino function is a highly appreciated functional group. It is more reactive than the corresponding PEG alcohol, and is used to form amide bonds with carboxylic acids. It also acts as a nucleophile, and participates in substitution reacti***.

Fmoc-amino PEG acid
Fmoc-amino PEG acids are ideal reagents for introducing spacer molecules in for example peptide chemistry. The Fmoc-protection regime is the most utilized in solid phase synthesis, thus allowing the PEG reagent to replace amino acids in automated protocols.
Fmoc-Amino PEG Propionic Acid
Fmoc-Amino PEG Propionic Acid
Boc-amino PEG amine
The Boc group is commonly used as temporary protection for the amine. It is stable during normal reaction conditi*** for amines, and can be deprotected by acid.
Boc-Amino PEG-6 Amine
Boc-Amino PEG-10 Amine
Azido-PEG
Azido-PEG amine can be used for synthesis applicati*** where one group must be protected. The azide group is transformed to an amino group by reducing agents.

Azido-PEG Amine
Azido-PEG
PEG Diamine
We supply PEG diamines in various lengths. Please inquire for molecular weights.
PEG Diamine
Protected amine
The amino group requires protection for use in reaction schemes. We supply either Boc- or Fmoc-protection for the derivatives. For alternative protection, please c***ider our azido-PEG derivatives.

PEG diacids are suitable for dimerisation reacti***, where both PEG ends react to identical moieties. For more complex strategies, please inquire for better suited alternatives. For price details click on the name of the product below.
PEG Diacid
Boc-amino PEG acid
PEG amino acids are provided with Boc-protection on the amine functi***. This allows acylation of the acid group without risk of polymerisation. The Boc group may be removed at a later stage by treatment with aqueous or organic acids.
