LifeTein Peptide Made in USA

LifeTein, located in Somerset, New Jersey, was founded in 2008 with a simple vision: understanding life sciences one protein at a time. This philosophy has formed the foundation of every peptide, protein, antibody, gene, and chemical project that we have completed for our customers in biotech, pharma, academia, government, diagnostics, and related organizations across the United States and in more than 30 other nations. We offer a wide range of custom peptide synthesis and conjugation services, custom protein, antibody and chemical services.

169 aa long peptide

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

LifeTein's technology is optimized to provide a continuous flow of synthesized peptides, while reducing costs and maintaining high quality. utilizes the microwave technology to enhance the efficiency of synthesis. We have developed a revolutionary AdjuBoosterTM adjuvant based on the nanoparticle technology, which increases immune response and reduces the time required for antibody synthesis.

LifeTein® fully understands our clients' projects. Our knowledgeable and helpful service representatives serve customers in a timely manner. Please email info@lifetein.com, fax 1-888-791-1618, or call 1-732-444-3282, and one of our peptide synthesis or antibody production specialists will tell you how we can meet your needs.


Positive Reviews. Publications citing LifeTein.

Positive Review received for Polyclonal antibody production (January 10, 2017):

"Excellent and expedient service. We used our polyclonal ab for western blotting of endogenous protein in cell lysates and it worked great with absolutely no background. We have CRISPR KOs cell lines to show that the specificity of the antibody is perfect! This was a major roadblock in our work that has been solved. Thank you!"

Positive Review received for Compound synthesis (December 02, 2016):

"I cannot recommend Life Tein enough. They were fantastic to work with and our laboratory will continue to contract with them in the future. Life Tein was the lowest bidder for two compounds. One compound was fairly simple in synthesis, whereas the other was quite complicated. The easy to synthesize compound was made in a timely manner. We had concerns about the identity of the compound due to a difference in LCMS data than what we expected. Life Tein offered without asking to send a small aliquot of the compound to us to ease our concerns. In the end, Life Tein was correct and had produced a highly pure product and sent the rest of the preparation to us within a week. The more complicated product was difficult to purify; however, the company tried many methods of purification that I believe goes above and beyond other synthesis companies I have dealt with. I would recommend them to anyone looking for a synthesis company!"

Positive Review received for Peptide synthesis (September 24, 2016):

"LifeTein delivered on time and it was very easy to work with them. Communication was great and the price was right. I would definitely work with them again."

Positive Review received for Peptide synthesis (May 27, 2015):

"We worked with LifeTein on the synthesis of a short peptide for part of Study 15 of the Reproducibility Project: Cancer Biology. LifeTein was communicative and especially helpful at hammering out the details of our requirements, and helped us write up the protocols for the Registered Report. They delivered the peptide on time, and kept us in the loop as the synthesis was proceeding. We highly recommend LifeTein for peptide synthesis!"

8 Reasons to Switch to LifeTein for Peptide Synthesis. Publications citing LifeTein.

Make LifeTein your trusted partner for peptide synthesis: save time, save money, and see better results.

  1. It’s Never Been More Affordable: We offer a range of innovative, high-quality solutions to fit any laboratory budget. LifeTein's PeptideSynTM technology reduces the cost of total peptide synthesis to allow us to offer the industry’s most competitive prices.
  2. Save Time: You are tired of waiting. Your campus core facility might seem convenient and economical, but the cost of waiting for facilities to be available and re-running projects to correct mistakes adds up. LifeTein's PeptideSynTM technology can save you hours, even days, of precious research time.
  3. 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.
  4. Focus on Innovation: Our rigorous quality control process guarantees that only correctly synthesized proteins are delivered so that your success is no surprise.
  5. Instantly Scale up or down: Our facilities and staff can produce libraries, simple peptides, and fill orders of even hundreds of peptides at extremely short notice. Our infrastructure is here when you need it, without draining your budget when you don’t.
  6. 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.
  7. High Peptide Yields: Breakthrough research by LifeTein created the PeptideSynTM platform, which delivers high yields of peptides rapidly every time. We always deliver more peptide than your specified amount.
  8. Improved Productivity: Get your drug discovered faster by using our proprietary peptide library technology for T-cell epitope and peptide lead discovery studies, and perform characterization on proteome-wide levels.
