Abstract:
MicroRNAs (miRNAs) are 20-23 nucleotide (nt) RNA molecules that regulate gene expression post-transcriptionally. A key step toward understanding the function of the hundreds of miRNAs identified in animals is to determine their expression during development. Here we performed a detailed analysis of conditions for in situ detection of miRNAs in the zebrafish embryo using locked nucleic acid (LNA)-modified DNA probes and report expression patterns for 15 miRNAs in the mouse embryo.

Types of probes and labels
A probe is a complementary strand of DNA or RNA that binds to corresponding nucleotide sequences in a cell. Many...
Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
