Fixed cells with different nucleic acid contents and scatter properties (low nucleic acid [LNA], high nucleic acid 1 [HNA1], and HNA2) were sorted by flow cytometry (FCM). For each sort, 10,000 cells were efficiently captured on poly-l-lysine-coated microplates, resulting in efficient and reproducible PCR amplification.

Scrapie can be transmitted by novel infectious pathogens termed prions. No evidence for a scrapie-specific nucleic acid has been detected to date. To investigate amounts, types and sizes of nucleic acid molecules associated with prions in purified preparations, aliquots were deproteinized, and the nucleic acids analysed by PAGE and silver staining. Digestion with nucleases and exposure to Zn2+ ...

Locked Nucleic Acid (LNA) is a unique nucleic-acid modification possessing very high binding affinity and excellent specificity toward complementary RNA or DNA oligonucleotides. The remarkable properties exhibited by LNA oligonucleotides have been employed in different nucleic acid-based therapeutic strategies both in vitro and in vivo. Herein, we highlight the applications of LNA nucleotides f...

(a) The nature of the problem Genes are made of nucleic acid. Enzymes are made of protein. The amino acid sequence of a particular protein is synthesized under instruction from a particular piece of nucleic acid. Each protein is made of one or more polypeptide chains, synthesized by condensing together amino acids, head to tail, with the elimination of water. A typical polypeptide chain is seve...

Approaches such as gene therapy and nucleic acid-based therapies are emerging in recent deals related to potential treatments for ophthalmic diseases.
