Photomodulating RNA cleavage using photolabile circular antisense oligodeoxynucleotides. grating surface using OptoDexTM photolinker material. Because of her resilience, 28 other survivors of trafficking were freed, too. Thanks to support from people like you, we were able to bring Ramona to safety after she escaped her trafficker. Tang, X., Su, M., Yu, LiLi, Lv, C., Wang, J., Li, Z. Key Holders' impact on survivors ripples outward Supporting one survivor can bring hope to countless more. Uncaged is a biomaterials company combining the power of nature and technology to reimagine leather. Photocleavable peptide-DNA conjugates: synthesis and applications to DNA analysis using MALDI-MS. Olejnik, J., Ludemann, H-C., Olejnik, E.K, Berkenkamp, S., Hillenkamp, F., Rothschild, K.J. Photocleavable aminotag phosphoramidites for 5'-termini DNA/RNA labeling. Olejnik, J., Krzymanska-Olejnik, E., Rothschild, K.J. Try using a Black Ray XX-15 UV lamp (Ultraviolet Products Inc., San Gabriel, CA) at a distance of 15 cm (emission peak 365 nm, 300 nm cut-off, 1.1 mW intensity at~31 cm).ġ. Caged siRNAs with a single photolabile linker and/or vitamin E (vitE) modification at the 5 terminal were rationally designed and synthesized.

PC Linker-modified oligonucleotides are the centerpiece of Bruker Daltonik's genoSNIP, a MALDI-TOF MS based assay system for SNP detection (4).Ĭleavage occurs by irradiation with near-UV light (300-350 nm, complete cleavage occurs within 5 minutes. The use of PC Linker has also been explored in designing multi-functional single-stranded nucleotide conjugates for use in in vitro selection of novel DNA or RNA-based catalysts for bio-molecular or organic reactions (for example Diels-Alder) (2,3).
Upon irradiation by UV light, photo-cleavage released a 5-phosphorylated 18-mer oligonucleotide having 9X greater hybridization affinity for a complementary DNA strand. Untreated:Normal Wildtype Caged:Normal Ru-cMO - hv Uncaged:Abnormal Ru-cMO+hv Treated:Abnormal MO control Advantages Controlled, efficient, and specific. They incorporated PC Linker into the sugar-phosphate backbone of a DNA hairpin. The photolinker is easily attached using click chemistry and can be used with a variety of biologics, including peptides, oligonucleotides, oligosaccharides, and lipids. (b) The engineered contact lens was immersed in PBS bath and exposed to the daylight for 8 h its color changed from transparent to slightly yellow (the color of uncaged photolinker) after the exposure. The utility of PC Linker for photo-triggered hybridization applications was first demonstrated by Ordoukhanian and Taylor in 1995 (1). The latest installer that can be downloaded is 14.9 MB in size. Exposure to the daylight led to the release of timolol, while the uncaged product remained chemically bound on the contact lens. Photo-cleavage of PC Linker by UV light yields one 5'-phosphorylated oligo and one 3'-phosphorylated oligo. PC Linker (photocleavable) is a non-nucleosidic molety that can be used to link two nucleotide sequences through a short, UV photo-cleavable C3 spacer arm, this can be added at any position of the sequence.
