UV Cleavable Biotin-PEG2-alkyne contains a UV cleavable fragemnt, the reagent is reactive with azide containing molecule via click chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

UV Cleavable Biotin-PEG2-Azide is a biotin linker. The azide group can react with either alkyne moiety in Cu(I)-catalyzed Click Chemistry reaction or DBCO moiety in copper-free Click Chemistry reaction to form a stable triazole linkage. The hydrophilic PEG spacer increases solubility in aqueous media of the molecules conjugated to the biotin compound. Captured target can be released under mild photolysis conditions (365 nm) and results in a significant decrease of background signal due to non-specifically bound proteins. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG2-C4-alkyne is biotinylation reagent that can react with azide moiety in Cu(I)-catalyzed Click Chemistry reaction to form a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG2-C6-azide is PEG linker containing a biotin group and an azide group. The azide group can react with either alkyne moiety in Cu(I)-catalyzed Click Chemistry reaction or DBCO moiety in copper-free Click Chemistry reaction to form a stable triazole linkage. The spacer arm helps to minimize steric hindrance involved with the binding to avidin molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Aminooxy-PEG3-azide is a crosslinker containing an aminooxy group and an azide group.The azide group is reactive with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. 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. 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.

Propargyl-PEG4-Tos is a PEG linker containing a tosyl group and a propargyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DSPE-PEG-PDP, MW 2,000 is a linear polyPEG containing a DSPE lipid group and PDP. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The PDP group selectively reacts with thiol, sulfhydryl or mercapto to form a disulfide bond. Reagent grade, for research purpose.

Bromoacetamido-PEG3-t-butyl ester is a PEG linker containing a bromide group and a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azide-PEG5-Tos is a crosslinking reagent with two functional groups. PEG spacer increases solubility in aqueous media. The azide(N3) group is reactive with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The tosyl group is a good leaving group for nucleophilic substitution reactions.
