(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.

Description

(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[1].

In Vitro

(Des-Pyr1)-LHRH (100 ng mL-1) acts as a stable, concentration-independent internal standard for LC-MS/MS quantification of gonadorelin in 1:10 diluted human urine samples, with no detectable degradation after freeze-thaw cycles[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
