PEG MGF 4mg / 2ml Mechano growth factor (MGF) is a novel splice variant of the insulin growth factor -1 (IGF-1), also known as IGF-1Ec in humans and IGF-1Eb in rodents. It is actually originally called MGF because the RNA form of it is expressed in muscle tissues in response to the overload or/and damage. The C-terminal peptide of the mechano growth factor (MGF) is a crucial region for the alternative splicing of the peptide. 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.
Storage Information: Lyophilized Peptides need to be stored in refrigerator or freezer to preserve shelf life.
Lyophilized peptides should be refrigerated and stored away from bright light. For short-term storage ranging from one week to two months, lyophilized peptides may be stored at 4 degrees Celsius. For long-term storage, lyophilized peptide should be stored at -20 degrees Celsius in deep freezer. Even though this condition keeps most peptides stable for several years, peptides' long term stability is at risk when peptides expose to moisture, therefore, the vial should be tightly capped at all times. This also requires careful experiment planning to minimize vial openings.
Repeated freeze-thaw cycles should be avoided for both lyophilized peptides and peptide solutions. If peptide samples need to be frequently or periodically taken from the stock, it is recommended to make a series of aliquots from the stock.
Peptide sequences containing C, M, or W are prone to air oxidation. It is recommended to purge the air out of the vial and replace it with a blanket of nitrogen or argon.
In general, peptide solutions are stable for up to a week at 4C. However, if the peptide sequence has inherent instability (Peptide Stability), it might be better to freeze the solution when not in use. Peptide solutions at pH>8 should also be frozen when not in use.
