Amino-PEG8-t-Boc-hydrazide is a crosslinker containing an amino group and a Boc-protected hydrazide. The hydrophilic PEG spacer increases solubility in aqueous media. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The Boc can be deprotected under mild acidic conditions to form a reactive hydrazide, which can then be coupled with various carbonyl groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Fmoc-N-amido-PEG4-t-Boc-Hydrazide is a PEG reagent containing an Fmoc-protected amine and a Boc-protected hydrazide. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The hydrophilic PEG spacer increases solubility in aqueous media. The Boc can be deprotected under mild acidic conditions to form a reactive hydrazide, which can then be coupled with various carbonyl groups. Reagent grade, for research purpose.

Biotin-PEG12-NHS ester is a bifunctional PEG linker featuring a biotin group and an activated NHS ester. The NHS 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.
Biotin-PEG11-amine is monodisperse PEGylated biotinylation reagent.The amine group can be coupled to carboxyl groups or 5'phosphate groups to form stable amide bonds. The hydrophilic PEG spacer increases aqueous solubility of the molecules conjugated to the biotin compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
Biotin-PEG11-Mal is a PEGylated biotin reagent PEG linker containing a maleimide (Mal) group.The maleimide gmoiety reacts specifically with sulfhydryl groups (at pH 6.5-7.5) to form a thioether linkage. The hydrophilic PEG spacer increases solubility in aqueous media of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
