Peptide Mass Fingerprinting Service Based on ESI-QTOF MS

STEMart offers Peptide Mass Fingerprinting Services using the advanced ESI-QTOF MS (Electrospray Ionization Quadrupole Time-of-Flight Mass Spectrometry), a powerful tool that provides high-resolution mass analysis of peptides. This instrument is an essential component of our laboratory, allowing us to achieve accurate mass measurements and detailed peptide analysis with exceptional sensitivity. ESI-QTOF MS enables the identification of peptides and proteins from complex biological samples, making it a vital tool for a wide range of research applications.

ESI-QTOF MS operates on the principle of electrospray ionization, which generates ions from liquid samples, and time-of-flight mass spectrometry, which measures the mass-to-charge ratios of ions. This combination allows for highly accurate mass measurements and the identification of peptides based on their mass spectra. ESI-QTOF MS is widely applied in proteomics, biopharmaceutical research, and biomarker discovery, offering precise data for studying protein structure, function, and interactions.

Leveraging our expertise in mass spectrometry and state-of-the-art ESI-QTOF MS technology, STEMart provides a comprehensive range of peptide mass fingerprinting services. Whether you require routine peptide identification or detailed analysis of post-translational modifications, our services are designed to support your research and development projects with high-quality data and insights.

What We Offer

• Peptide Mass Fingerprinting Service

We use ESI-QTOF MS to generate mass fingerprints of peptides, allowing for accurate identification by comparing the fingerprints to known peptide databases.
