Supplementary Protocol for RNA SPOTs

Probing binding hot spots at protein-RNA recognition sites.

We use evolutionary conservation derived from structure alignment of polypeptide sequences along with structural and physicochemical attributes of protein-RNA interfaces to probe the binding hot spots at protein-RNA recognition sites. We find that the degree of conservation varies across the RNA binding proteins; some evolve rapidly compared to others. Additionally, irrespective of the structur...

RNA sequencing of archived neonatal dried blood spots

Neonatal dried blood spots (DBS) are routinely collected on standard Guthrie cards for all-comprising national newborn screening programs for inborn errors of metabolism, hypothyroidism and other diseases. In Denmark, the Guthrie cards are stored at - 20 °C in the Danish Neonatal Screening Biobank and each sample is linked to elaborate social and medical registries. This provides a unique biosp...

RNA nanotechnology breakthrough for targeted release of RNA-based drugs using cell-based aptamers

Nucleic acids play different roles besides storing information and proteins coding. For example, single-stranded nucleic acids can fold into complicated structures with capability of molecular detection, catalyzing bioreactions and therapy. The development of RNA-based therapies has been rapidly progressed in the recent years. RNA aptamers are biomolecules with a size of 10 to 50 nm that can be...

Qualitative human immunodeficiency virus RNA analysis of dried blood spots for diagnosis of infections in infants.

The Gen-Probe Aptima human immunodeficiency virus type 1 (HIV-1) RNA assay was adapted for the diagnosis of HIV infection in infants by using dried blood spots. The assay was 99% sensitive (128/129) and 100% specific (162/162). This may prove useful in resource-limited settings, since it precludes the need for a phlebotomist and maintenance of a cold chain.
