PTO BIO is dedicated to developing and providing innovative research products and services to fundamentally transform the way we understand, diagnose, and treat human diseases.
Our Mission
To advance precision medicine by leveraging the power of proteomics.
Proteomics-Driven Precision Medicine
Disease-relevant biomarkers discovery based on proteomic profiles of healthy and diseased patient samples
Next-generation precision companion diagnostics development with our expertise in high-quality antibodies generation
Effective and safe precision therapies design based on novel biomarker-guided drug discovery strategy
Products & Services An Integrated Platform
Our integrated platform consisting of proprietary PTM reagents, sophisticated mass spectrometry expertise, advanced bioinformatics tools, has been profoundly benefiting biomedical and pharmaceutical research, as demonstrated by continuous high-profile publications and long-term collaborative relationship with top tier drug discovery organizations.
We are well positioned to apply state-of-the-art proteomics strategies in conjunction with next generation sequencing-based genomics and transcriptomics techniques to improve therapy selection for patients, and to discover a brave new world of medical possibilities.
Our Products
We supply the world’s most comprehensive coverage of post-translational modification (PTM) antibodies, with 21 different modification types and over 400 PTM antibody products. Antibodies developed by PTM BIO have made indispensable contribution to a variety of novel histone mark discoveries, including lysine lactylation, succinylation, crotonylation, etc. We have also built robust high throughput platform for recombinant rabbit monoclonal antibody generation.
Our PTMab® products now cover:
