Hui-Lung Sun. et al. Stabilization of ERK-Phosphorylated METTL3 by USP5 Increases m6 A Methylation; Mol Cell; 2020 Nov 19;80(4):633-647.e7. doi: 10.1016/j.molcel.2020.10.026.

LifeTein helped synthesized a series of phosphorylated peptides. Then the peptides were used for phospho-specific p-METTL3 (S43) antibody productions. Sun et al. demonstrate that activation of the ERK pathway promotes m6A methylation by phosphorylation of METTL3 and WTAP.

Jia Shen. et al. EGFR modulates microRNA maturation in response to hypoxia through phosphorylation of AGO2. Nature 497, 383–387 (16 May 2013), doi:10.1038/nature12080

LifeTein helped designed and synthesized a series of phosphorylated peptides. Then the peptides were used for phospho-specific antibody productions. The phospo-specific antibodies by LifeTein were confirmed to react with the epidermal growth factor receptor (EGFR). The Hung's lab showed that AGO2-Y393 phosphorylation mediates EGFR-enhanced cell survival and invasiveness under hypoxia. These findings suggest that modulation of miRNA biogenesis is important for stress response in tumour cells.

... The following peptides were chemically synthesized for antibody production in mice (Lifetein Conc.), Elisa verification (LifeteinConc.) and peptide competition assay in immunohistochemistry (IHC)... Supplementary information

George R. Tiller, Potential Roles of Peroxidases in Caenorhabditis Elegans Innate Immunity. 2014

Custom peptide antibodies were provided by LifeTein to study SKPO-1. The SKPO-1 peroxidase domain peptide was synthesized by LifeTein. The polyclonal antibodies were raised in rabbits and then affinity purified to accomplish high specifications and concentrations. The antibodies were successfully used to localize the SKPO-1 protein in hypodermis. It was found that the peroxidase SKPO-1 contributes to the host immune response during infection.

... With respect to having a pAb raised for IHC, I designed a synthetic SKPO-1 peroxidase domain peptide to be chemically synthesized and have a pAb raised in rabbits against said peptide by Lifetein®. This endeavor was successful and is covered in Chapter 3...
