Peptide, Protein, and Antibody Research Platform
LifeTein supports academic, government, biotech, and pharmaceutical research programs with integrated capabilities in peptide synthesis, recombinant proteins, antibodies, and custom research reagents. Our platform is designed to support discovery, assay development, validation, immunology research, and preclinical studies with flexible catalog and custom solutions.
Peptide Expertise
Custom peptides, difficult sequences, peptide libraries, labeled peptides, CPPs, PNA, and specialty research peptides.
Protein Platform
Recombinant proteins, cytokines, growth factors, MHC complexes, VLP antigens, checkpoint proteins, and specialty proteins.
Antibody Support
Epitope tag antibodies, loading controls, signal transduction antibodies, rabbit antibodies, and related assay reagents.
What We Support
LifeTein works with a wide range of research groups, including academic laboratories, federal and state research institutions, CROs, biotech companies, and pharmaceutical teams. Our platform is intended to support projects ranging from basic research and biomarker studies to assay development, screening, immunology, and translational research.
We provide both catalog products and custom development support. Many customers use LifeTein when they need a responsive partner for specialized reagents, difficult sequences, or niche products that require more flexibility than standard catalog sourcing.
