Research Abstract

In this study, we investigated receptor for Mannose-binding protein(MBP1) which thought to be need for establishment of acanthamoeba keratitis. We made MBP1 chimera protein by cell free system and analyzed binding protein with the MBP1 chimera protein by MALDI-TOF/MS. Also we made ubiquitin promoter fluorescent protein constructs, and then we made fluorescent protein labeled acanthamoeba.
