BACKGROUND STORAGE AND RESUSPENSION Dyskerin (NAP57) associates with the chaperone Nopp140 and forms Store lyophilized shRNA plasmid DNA at 4° C with desiccant. Stable for a small ribonucleoprotein particle with GAR1 (NOLA1), NHP2 (NOLA2) and at least one year from the date of shipment. Once resuspended, store at Nop10 for the isomerization of uridine to pseudouridine. GAR1, NHP2 and 4° C for short term storage or -80° C for long term storage. Avoid repeated Dyskerin localize to the dense fibrillar component of the and in freeze thaw cycles. nuclear Cajal bodies. The Dyskerin maps to Xq28. Missense Resuspend lyophilized shRNA plasmid DNA in 200 µl of the deionized water mutations in the Dyskerin gene interfere with normal nuclear localization of provided. Resuspension of the shRNA plasmid DNA in 200 µl of deionized dyskerin and cause Dyskeratosis congenita (DKC). DKC is a rare, X-linked bone water makes a 0.1 µg/µl solution in a 10 mM Tris, 1 mM EDTA buffered marrow disorder characterized by cutaneous hyperpigmentation, dystrophy solu tion. of the nails, atrophy of the testicles and leukoplakia of the oral mucosa. The GAR1 gene maps to chromosome 4q25. The NHP2 gene maps to chromo - APPLICATIONS some 5q35.3 and encodes a 155-amino acid protein. Dyskerin shRNA Plasmid (h) is recommended for the inhibition of Dyskerin REFERENCES expression in human cells. 1. Hassock, S., et al. 1999.
