Description
Incretin-receptor agonists are long peptides, and long peptides reward careful handling. The 20 mg fill is for labs that will be working with this one for a while.
GLP-1 20 mg: handling a long peptide well
Peptides of thirty or more residues tend to adsorb onto glass and untreated plastic, especially at the low concentrations used in cell assays. Many labs add a carrier protein such as bovine serum albumin to dilution buffers, or use low-binding tubes, so that the concentration on the label is the concentration in the well.
Length also affects chromatography. Related substances such as deamidation or truncation products can elute close to the main peak, so purity methods for long peptides usually run shallower gradients than those for short ones. The certificate states the conditions used, which is what makes two results comparable.

Questions about GLP-1 Peptide 20mg
Why add a carrier protein when diluting?
It coats surfaces so the peptide does not stick to them, keeping dilute concentrations accurate.
What are related substances?
Closely related impurities such as truncated or deamidated forms. A good HPLC method resolves them from the main peak.
Is 20 mg the best value per milligram?
Among the GLP-1 fills, yes, before any quantity break.
