BGI Americas now offers proteomic and biologics characterization services to accelerate your life science research program. Our new portfolio of end-to-end LC-MS services leverages BGI’s strengths in managing large scale computing infrastructure and pioneering innovative bioinformatics technologies.

Our mass spectrometry service laboratory in San Jose, CA is comprised of scientists with extensive experience in liquid chromatography and mass spectrometry-based analytical methods. This state-of-the-art facility is designed to support a broad range of protein research applications.

We can help simplify your research challenge. BGI can provide workflow customization and consultation services to address unique project requirements. Turnaround time is 1 or 2 weeks for certain premium services.

Proteomic Services

BGI provides global and targeted solutions for protein quantitation^1,2. We can flexibly adapt our Label-Free DIA and Isobaric Label TMT services to best fit your experimental strategies^3,4,5. For screening applications we provide a highly specific targeted peptide quantitation using Parallel Reaction Monitoring (PRM) scanning using high resolution Orbitrap MS detection⁶.

We offer services for large scale proteomic profiling and can provide sample pre-fractionation using our off-line UHPLC-UV platform. Our laboratory can also perform Protein Identification services using solution samples or gel-isolated samples.

All of our proteomic services can be customized to meet your drug discovery project needs.

Biologics Characterization Services

BGI scientists in San Jose, California, provide analytical services and downstream support for biopharmaceutical and biotechnology industry customers. Our goal is to provide you with detailed knowledge about the molecular composition of your biologic sample using innovative analytical methods optimized for dynamic range and sensitivity.

Our state-of-the-art LC-MS platform can support diverse biologic characterization projects, including highly complex samples such as bi-/multi-specific antibodies, ADCs, and Fc-fusion protein drugs. Additionally, our scientific team at the San Jose Mass Spectrometry Center have pioneered native LC-MS technology which can preserve non-covalent binding and is compatible with medium-high sample throughput^7,8,9.

We can provide broad support for drug discovery and other biologic-related proteomics services, including phosphoproteomics, CAR-T interactomics, and trans-omics projects involving proteomic and transcriptomic (DNBseq) analyses.
