The Ca2+-Regulated Photoprotein Obelin as a Target for the RNA Aptamer Selection
A variant of the Ca2+-regulated photoprotein obelin elongated with a hexahistidine peptide from the N-terminus was developed and studied. After immobilization on a metal-affine sorbent, the hybrid protein was applied as a target for the in vitro selection of RNA aptamers. According to the data of bioluminescent solid-phase microanalysis, the selection was shown to enrich the RNA library with obelin-affine molecules.
