Description:

mPEG-CHO  is one of Ponsure site specific pegylation reagents that can react with N-terminus amine (-NH2) groups at acidic pH, a condition required sometime by certain special pegylation needs. Aldehyde PEG reacts with ε-amine of lysine residues and the α- amine at the N-terminus produces an intermediate Schiff base. Further reduction with hydride results a stable C-N bond. Reaction between PEG aldehydes and amine occurs at pH from 5.5 to 9.5. Higher pH will result in multiple Pegylation with both terminal and lysine groups reactive PEG derivative that can be used to modify protein, peptide or any other surfaces.

Handling and Use:

mPEG-CHO  is sensitive to light and temperature. For best use, material should always be kept in low temperature in dry condition.

 Avoid frequent thaw and freezing. For more information about using this product, visit www.ponsure.com.

Storage Conditions：

mPEG-CHO should be stored at -20℃. Desiccate.  Materials may be handled under inert gas for best stability. Re-test material after 12 months.
