Our Free QC Offer:

Purity is of utmost importance in peptide based research. Many impurities, as artifacts of the synthesis process, may be closely related to the target molecule and have unexpected agonistic or antagonistic activity.

As an introductory offer to showcase our analytical services Global Peptide will perform analytical HPLC and mass spectrometry to verify the mass and purity of your synthetic peptide.

Reported Purity is Not Always Actual Purity

Global peptide purchases synthetic peptides from a variety of sources for our research needs.

This peptide was reported 90.53% pure by the supplier.

When subjected to our rigorous QC methods, the reults were quite different.

Different Moble Phases May Affect reported Purity

Chromatograms of GLP-2
35-60%B over 25min, 1.5 ml/min.

Mobile phase B: Acetonitrile.

Moblie Phase A:
(a) 0.1% TFA/water
(b) 0.1M aq. TEAP
(c)0.1M aq. KPF6
