Srinivasan, P. et al. Disrupting malaria parasite AMA1–RON2 interaction with a small molecule prevents erythrocyte invasion. Nat. Commun. 4:2261 doi: 10.1038/ncomms3261 (2013).

Biotin-RON2, a synthetic biotinylated 42 mer peptide, was synthesized by LifeTein. Synthetic peptides are crucial in the process of understanding protein-protein interactions. Using a high throughput screen method, Prakash Srinivasan assessed the inhibitors that block interactions between AMA1-RON2. He shows that the inhibitor binds to AMA1 and prevents its interaction with RON2. Such inhibitors of merozoite invasion used in combination with existing antimalarials hold great promise as a novel therapeutic approach in the fight against malaria.

... Biotin-tagged RON2 peptide(DITQQAKDIGAGPVASCFTTRMSPPQQICLNSVVNTALSTSTQSAMK) with the two cysteines cyclized was synthesized and purified (95% pure) by LifeTein, LLC USA (New Jersey, USA) ...

Synthetic peptides by LifeTein were used as substrate to study the protein structure and function. ET Smith and DA Johnson found that the positively charged peptides could contribute the substrate specificity in human enteropeptidase. It shows importance of the charge-charge interactions in the substrate binding pocket. For example, peptide DDDDK and DDDDR could have different specificities for substrates.

... The extended peptide substrates GD4K-pNA and GD4R-pNA (LifeTein) were used at concentrations between 0.02-1.0 mM and 5-100 µM, respectively. Reactions were initiated by adding enzyme to ...

Paul M. Arnaboldi, et al. An outer surface protein C (OspC) peptide derived from Borrelia burgdorferi sensu strico as a target for the serodiagnosis of early Lyme disease, Published ahead of print 30 January 2013, doi: 10.1128/CVI.00608-12

LifeTein advanced the research on serodiagnostic assays for Lyme disease. The linear epitopes OspC1 was synthesized by LifeTein. This highly conserved 20 amino acid peptide epitope detected specific IgM and/or IgG in 60 out of 98 serum samples. This OspC1 peptide could have value as a component of a multi-peptide Lyme disease serological assay with significantly improved capabilities for the diagnosis of early infection. OspC1 was proved to have higher specificity than the commercial available OspC peptide.

... A positive signal was required to be at least 4x the FSI of the negative assay control. Peptides chosen for further analysis were produced by Lifetein, Inc. (South Plainfield, NJ), and were a minimum of 90% purity. ...
