Abstract
CLE peptides are important signaling molecules that regulate the balance of proliferation and differentiation of plant cells. In this work, we conjugated gold nanospheres (15 nm) with a chemically synthesized peptide (12 amino acid residues) that the amino acid sequence corresponds to the natural peptides CLE41/44. The "golden number" for CLE41/44 was 2 Μg/mL. A stable conjugate was used to produce rabbit polyclonal antibody. By the method of dot analysis, the presence of antibodies to CLE41/44 was detected in antiserum. Using Western blot and ELISA methods, the reaction of the obtained antibody with a conjugate of CLE41/44 with BSA molecules was demonstrated. The obtained antibody is can potentially be used to the quantitative determination and identification of the localization of peptides in plant tissues.
