LifeTein Peptide Oligonucleotide Conjugate

DNA-Peptide and RNA-Peptide

PeptideSyn Peptide Synthesis Technology

LifeTein routinely uses our proprietary technology to produce peptides >100 aa. The longest peptide we have made to date is 169aa.

Reasons to Switch to LifeTein for Peptide Synthesis

  • It’s Never Been More Affordable

    We offer a range of innovative, high-quality solutions to fit any laboratory budget.

  • Save Time

    LifeTein's PeptideSyn technology can save you hours, even days, of precious research time.

  • Avoid Mistakes

    We offer free aliquoting for your peptides. Aliquoting prevents the breakdown of peptides in stock solution that can be caused by repeated freeze-thaw cycles.

  • Ph.D.-Level Support

    Our dedicated teams are committed to your successful peptide design (free), peptide synthesis, and antibody production to meet your evolving needs.

Our Promise

Free HPLC/MS Data 100%
Turnaround Time 95%
Difficult Modifications 90%
Free Peptide Antigen Design 100%
Antibody Success Rate 95%
Chemical Synthesis Success Rate 80%
