Protein Identification Service Based on MALDI-TOF MS

STEMart provides advanced Protein Identification Services using the MALDI-TOF MS (Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry), a powerful tool that enables precise and efficient protein identification. This instrument plays a crucial role in our laboratory, offering rapid, high-throughput analysis with exceptional mass accuracy. With MALDI-TOF MS, we can process complex protein mixtures with high sensitivity, delivering reliable results for various research and industry applications.

MALDI-TOF MS works by ionizing large biomolecules, such as proteins, with minimal fragmentation, followed by measuring their mass-to-charge ratio through a time-of-flight mass analyzer. The technique is particularly valuable in proteomics, biomarker discovery, and clinical diagnostics, where it is used to identify proteins, study protein interactions, and analyze post-translational modifications. The method’s wide applicability makes it indispensable in life sciences, biotechnology, and pharmaceutical research.

Leveraging our expertise and state-of-the-art mass spectrometry equipment, STEMart offers a comprehensive range of services to meet the specific needs of our clients. Our capabilities include routine protein analysis, complex post-translational modification studies, and customized workflows tailored to your research objectives. We provide accurate data and insights to support your research and development projects.

What We Offer

• Protein Mass Fingerprinting Service

We generate unique mass fingerprints of proteins using MALDI-TOF MS, enabling fast and accurate identification by comparing the fingerprints to known protein databases.

• Post-Translational Modification Analysis

Our service identifies and characterizes post-translational modifications (PTMs) using MALDI-TOF MS, critical for understanding protein function and regulation.

• Protein De Novo Sequencing

For proteins without existing sequence information, we offer de novo sequencing using MALDI-TOF MS to determine the amino acid sequence directly from the sample.

• Glycoprotein Analysis

We provide comprehensive glycoprotein analysis using MALDI-TOF MS, characterizing attached glycans and detailing glycosylation patterns in proteins.
