What is the Pegylation of Mechano Growth Factor?
PEGylation is the act of attaching a Polyethylene glycol (PEG) structure to another larger molecule (in this case, MGF). The PEG acts as a protective coating and the theory here is that this will allow the MGF to be carried through the blood stream without being broken down. Neurological research has shown that utilizing PEGylated MGF resulted in a longer more stable acting version of the MGF peptide in serum/blood.
The Effects of Pegylated MGF
Mechano Growth Factor (MGF) exhibits local effects in skeletal muscle and without cannot travel through the body without modification. The problem with synthetic Mechano Growth Factor (MGF) is that it is introduced intramuscularly and is water based so it goes into the blood stream. When used this way, Mechano Growth Factor (MGF) only remains stable in the blood stream for a few minutes. Biologically produced MGF is made locally and does not enter the bloodstream. It is also short acting so stability is not an issue. By PEGylating the Mechano Growth Factor (MGF) it is almost as efficient as local produced Mechano Growth Factor (MGF) when used intramuscularly. This is accomplished by surrounding part of the peptide with a structure of polyethylene glycol, which can be attached to a protein molecule. The polyethylene glycol groups protect the peptide but do not surround it completely. The active sites of the peptide are still free to do their biological function. In this case the shell is a negative charged shield against positively charged compounds that would affect the protein.
