| 摘要 |
A method for probing a target sequence of messenger ribonucleic acid molecules (mRNA's) in a fixed, permeabilized cell, said target sequence including at least 30 non-overlapping probe binding regions of 15-100 nucleotides, comprising immersing said cell in an excess of at least 30 nucleic acid hybridization probes, each singly labeled with the same fluorescent label and each containing a nucleic acid sequence that is complementary to a different probe binding region of said target sequence; washing said fixed cell to remove unbound probes; and detecting fluorescence from said probes.
