Multiplexed Imaging with Nanobody Probes

Abstract:

Methods include (a) contacting a biological sample with a composition featuring a plurality of different types of probes, where each type of probe of the plurality of different types of probes includes a detection moiety that selectively binds to a different type of protein target in the sample, a nanobody bound to the detection moiety, and an oligonucleotide linked to the nanobody and featuring an oligonucleotide sequence, where the oligonucleotide sequence of each type of probe is different from the oligonucleotide sequences of each of the other types of probes of the plurality of probes; and (b) contacting the sample with a set of one or more different types of optical labels, where each different type of optical label of the set of optical labels includes an oligonucleotide that selectively hybridizes to only one type of probe.
