Proximity ligation assays with peptide conjugate 'burrs' and aptamers for the sensitive detection of spores and cancer cells

摘要

The present invention includes compositions and methods for the detection of specific targets on a surface that includes one or more peptides and one or more oligonucleotides connected by a joint to a detectable marker, wherein the joint between the peptides, the oligonucleotides or both the peptides and oligonucleotides are immobilized.
