Abstract:This study explores the use of l-methionine derivative as a potential affinity ligand for nucleic acids purification. The l-methionine derivative is synthesized by activation of the carboxylic acid group with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxysuccinimide follow by immobilization on amine sensor surface, previously activated and treated with ethylenediamine. Their affinity towards oligonucleotides has been determined by surface plasmon resonance biosensor. The highest affinity is found for… Show more
