PEGylation of therapeutic proteins
Improved clinical properties:

Better physical and thermal stability

Protection against susceptibility to
enzymatic degradation

Increased solubility

Longer in vivo circulation
Approved for human use by the U.S. Food and Drug
Administration

PEGylation reaction
PEGylation is a reaction in which at least one chain of
polyethylene glycol (PEG) is attached to a molecule or
protein without changes in its properties.

Protein
di-PEGylated
Protein
 The mono-PEGylated protein in both models presents the
best biological activity.
Separation of PEGylated proteins
• Two basic challenges:
– the separation of PEG-proteins from other
reaction products.
– the sub-fractionation of PEG-proteins.

Rotavirus-like particles primary
recovery from insect cells
 Virus like-particles (VLP) are composed
of the main structural proteins of a virus,
but lack its genetic material.
 They are produced by the recombinant
expression of the structural proteins
 Applications: vaccination, biosensors,
nanomaterials.
VP6 VP2
Double layered rotavirus-like
particles (dlRLP)
 Consist of two concentric
protein layers.
VP6 VP2
 The inner layer is formed by
protein VP2, while the outer
layer is formed by protein
VP6.
 dlRLP induce immune
response to treat acute
gastroenteritis*.
*Annually, more than 500,000 children die as victims of acute
gastroenteritis caused by rotavirus (Kirkburk and Buttery, 2003).
