LifeTein Peptide oligonucleotide conjugate: DNA-Peptide and RNA-Peptide. Oligonucleotide-peptide conjugates are chimeric molecules composed of a nucleic acid moiety covalently linked to a peptide moiety. It is an important tool for studies of the protein– and peptide–nucleic acid interactions, as well as being promising bioconjugates for nucleic acid delivery and therapy.

Positive review received for Polyclonal Antibody Production:

"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!"

December 2, 2016

Positive review received for Compound Synthesis:

"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!"
