Pegylation & PEG Linkers

Pegylation & PEG Linkers / product groups & items in this category

Polyethylene glycol (PEG) linkers are necessary for bioconjugation and pegylation. Lumiprobe offers a range of PEG based products with different linker lengths, bearing various reactive groups.

  • Alkyne-PEG3-COOH
    Bifunctional linker with terminal alkyne function, and carboxylic acid moiety, CAS# 1415800-32-6.
  • Alkyne-PEG3-NHS ester
    Bifunctional hyrophilic linker with NHS ester and terminal alkyne functional group based on triethyleneglycol (PEG3).
  • Alkyne-PEG3-OH
    Alkyne-PEG3-OH is a triethyleneglycol based bifunctional linker with a hydroxyl group and an alkyne fragment.
  • Alkyne-PEG4-OH
  • Alkyne-PEG4-amine
    A bifunctional linker molecule containing both terminal alkyne moiety for Click chemistry, and amine group. Contains a long hydrophilic PEG4 arm.
  • Alkyne-PEG4-maleimide
    Water soluble, heterobifunctional hydrophilic linker with a length of 14 Å, containing maleimide for thiol labeling, and alkyne for Click chemistry. An ideal reagent to attach an alkyne moiety to a protein.
  • Azide-PEG3-Amine
    A bifunctional linker with azide and amine groups flanking PEG3 (triethylene glycol)
  • Azide-PEG3-Azide
    Triethylene glycol diazide (CAS# 59559-06-7) is a bifunctional crosslinker bearing two azide groups. Suitable for Click chemistry.
  • Chloro-PEG3-azide
    PEG3 azide chloride contains a reactive halogen atom, and an azide group for Click chemistry reaction. It can also serve as a protected amine group equivalent.
  • Iodo-PEG3-Acid
    A bifunctional compound containing carboxylic acid functional group, and iodide, an active halogen group.
  • Iodo-PEG3-Iodide
    Homobifunctional PEG3 based linker with halogen reactive groups is useful for the crosslinking of nucleophiles.
  • Iodo-PEG3-azide
    Iodo PEG3 azide is a bifunctional linker with a highly reactive alkylative halogen functional group, and an azido group for Click chemistry / Staudinger ligation.
  • PEG3 dicarboxylic acid
    PEG3 dicarboxylic acid is a bifunctional linker carrying two carboxy groups. It contains a polyethyleneglycol-3 linker between the carboxyls.
  • PEG3-tetrazine
    PEG3 tetrazine is a mono-reactive triethyleneglycol with a tetrazine group for ied-DA conjugation with strained olefins.
