Abstract:
The potential of the method of scanning electron microscopy (SEM) to visualize the results of individual acts of DNA and oligonucleotides hybridization using gold nanoparticles as label was investigated. Molecule of biotin was introduced into DNA or oligonucleotide, and then it was detected in DNA duplex using a conjugate of streptavidin with gold nanoparticles. Effective imaging of DNA duplexes was possible using a conjugate prepared by covalent binding.. The detection limit of the model oligonucleotide of 19 bases was 20 pg.

Labeling DNA Probes
9.9K
DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
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...

Immunogold Electron Microscopy
6.1K
Immunoelectron microscopy utilizes immunogold labeling of endogenous proteins with specific antibodies to detect and localize these proteins in cells and tissues. The procedure provides insights into the distribution and quantification of protein under different stimulation conditions offering clues about their functions. Conjugating highly electron-dense gold particles with primary or secondary antibodies allow antigen detection on and within cells, with high resolution and specificity.
