GHRH-analog peptides in research: CJC-1295 and PEG-MGF
Some research peptides are grouped by the pathway they are studied against. CJC-1295 and PEG-MGF are frequently discussed together as growth-factor research peptides. This article explains the class by its chemistry; it is not guidance for use.
CJC-1295
CJC-1295 is described in the literature as a growth-hormone-releasing-hormone (GHRH) analogue — a modified peptide used to study that signalling pathway in research models.
PEG-MGF
PEG-MGF is a pegylated form of mechano growth factor. Pegylation (attaching polyethylene-glycol chains) is a common chemistry technique researchers use to change a peptide’s solubility and handling — a useful example of how modification is studied.
Handled as reference materials
Neither is approved for any use. They are supplied and handled strictly as reference materials for laboratory research.
How these peptides is handled in the laboratory
Like our other reference materials, it is supplied as a lyophilised (freeze-dried) powder in a sealed vial. Researchers reconstitute it with a diluent such as bacteriostatic water before use. Every batch is independently verified by HPLC, mass spectrometry and an endotoxin (LAL) screen; see our testing standards or look a batch up on Verify a Batch.
