Thermo Scientific™ EZ-Link™ Iodoacetyl-PEG2-Biotin
Biotinylate reduced cysteines (-SH groups) at high pH with this haloacetyl-activated, sulfhydryl-reactive biotinylation reagent containing polyethylene glycol for solubility.
Supplier: Thermo Scientific™ 21334
Description
Thermo Scientific™ EZ-Link Iodoacetyl-PEG2-Biotin is a mid-length, haloacetyl-activated, sulfhydryl-reactive biotinylation reagent that contains a 2-unit ethylene glycol in its spacer arm for increased water-solubility characteristics.
Highlights:
- Water-soluble, polyethylene glycol (PEG) spacer arm
- Reacts with sulfhydryl (-SH) groups at basic to neutral pH
- Coupling reactions occur in the dark
- PEG spacer arm transfers hydrophilicity to final conjugate
- Forms a stable thioether bond
