(Des-Pyr1)-LHRH
Based on 1 Customer Validation
(Des-Pyr1)-LHRH is a Polypeptide Internal Standard, identical to (Des-Pyr1)-GnRH, which can be identified through peptide screening. Peptide screening is a research tool that mainly collects active polypeptides via immunoassays. It can be applied to protein interaction, functional analysis, epitope screening, especially in the field of active molecule research and development. (Des-Pyr1)-LHRH can serve as an internal standard (ISTD) for mass spectrometry analysis.
