Prediction of B cell epitopes of CD36 and preparation of MAP
Journal Title: Chinese Journal of Blood Transfusion - Year 2024, Vol 37, Issue 8
Abstract
Objective To analyze the structure of CD36, search the possible B cell epitopes and prepare multi-antigen peptides(MAP) with B cell epitopes, so as to provide a preliminary experimental basis for the preparation of CD36 antibodies using MAP with B cell epitopes. Methods The potential B cell epitopes of CD36 were analyzed by bioinformatics methods, including physical and chemical properties, secondary structure, potential phosphorylation and glycosylation sites. Eight-branch MAP with CD36 B cell epitopes were synthesized by FMOC using polylysine as the core matrix. The purity of MAPs was analyzed by reverse high-performance liquid chromatography chromatography(RP-HPLC), and the molecular weight of MAPs was determined by mass spectrometry. Results CD36 is a stable and hydrophilic alkaline protein, with multiple phosphorylation and glycosylation sites and strong antigenicity, and its secondary structure is mainly characterized by irregular curls. Four potential B cell epitopes were obtained and 4 MAPs containing potential B cell epitopes were prepared. RP-HPLC analysis showed that the purity of the MAPs were above 85%, and the molecular weight of 3 MAPs was consistent with the expected theoretical molecular weight. Conclusion CD36 on platelet has strong antigenicity. MAPs containing CD36 B cell epitopes can provide the experimental basis for the preparation and related research of CD36 antibodies.
