Methods are provided for detecting a glycosylated target protein in a sample. Aspects of the methods include: (a) contacting a sample comprising a probe-labeled glycosylated target protein with: (i) a first conjugate comprising a first nucleic acid tag linked to a first capture agent that specifically binds the target protein; (ii) a second conjugate comprising a second nucleic acid tag linked to a second capture agent that specifically binds the probe; and (iii) a bridging nucleic acid that hybridizes to the first and second nucleic acid tags; under conditions sufficient to specifically bind the first and second capture agents to the probe-labeled target protein and to hybridize the bridging nucleic acid to the first and second nucleic acid tags to produce a nucleic acid complex; and (b) detecting the nucleic acid complex. Also provided are compositions and kits useful in practicing various embodiments of the subject methods.
Tetra-tert.butylpyrazole (4) and tetra-tert.butylthiophene (11) were prepared starting from the seven membered cycloalkyne 1 and a reductive desulfurization in the last step. Some reactions of 4 and 11 are described. X-ray structural analyses of 11 and the corresponding S,S-dioxide were carried out.
