LifeTein peptides have been cited in many peer-reviewed publications, including studies requiring long peptide synthesis, fluorescent labeling, phosphopeptides, biotinylated peptides, cyclic peptides, and other challenging custom formats. This page highlights representative peptide capability areas rather than trying to function as a broad publications archive.
Featured example: Nature Communications (2026)
In a recent study on IRF2BPL, LifeTein synthesized two difficult custom peptides: a 54 amino acid peptide with N-terminal acetylation, C-terminal amidation, and >95% purity, and a 75 amino acid peptide with an N-terminal FITC tag linked through a 6-aminohexanoic acid (Ahx) spacer, C-terminal amidation, and >90% purity.

LifeTein synthesized a very long 54 aa peptide spanning the human IRF2BPL HCD core region (a.a. 395–448) with N-terminal acetylation, C-terminal amidation, and purity >95%. The same study also used a 75 aa peptide spanning the ZnF region (a.a. 1–75) with an N-terminal FITC tag linked through a 6-aminohexanoic acid (Ahx) spacer, C-terminal amidation, and purity >90%.
