Product Description Reconstitution Protocol PTPRE siRNA is a pool of three individual synthetic siRNA Briefly centrifuge the tubes (maximum RCF 4,000g) to duplexes designed to knock-down human PTPRE mRNA collect lyophilized siRNA at the bottom of the tube. expression. Each siRNA is 19-25 bases in length. The gene Resuspend the siRNA in 50 µl of DEPC-treated water accession number is BC050062. (supplied by researcher), which results in a 1x stock solution (10 µM). Gently pipet the solution 3-5 times to mix Gene Aliases and avoid the introduction of bubbles. Optional: aliquot PTPE, P-PTP-epsilon, HPTPE, R-PTP-EPSILON, RP11-380J17.1, 1x stock solutions for storage. DKFZp313F1310, FLJ57799, FLJ58245 Related Products Storage and Stability The lyophilized powder is stable for at least 4 weeks at Product Name Catalog Number room temperature. It is recommended that the PTPRA (LRP), Active P48-21G lyophilized and resuspended siRNAs are stored at or PTPRC (CD45), Active P50-21H below -20oC. After resuspension, siRNA stock solutions ≥2 PTPRC (CD45), Active P50-21BG µM can undergo up to 50 freeze-thaw cycles without PTPRE, Active P52-21G significant degradation. For long-term storage, it is PTPRF (LAR), Active P53-21G recommended that the siRNA is stored at -70oC. For most PTPRS(PTP-sigma), P64-21G favorable performance, avoid repeated handling and Active multiple freeze/thaw cycles. PTPRM (PTP-mu) Protein P58-35G Scientific Background PTPRE or protein tyrosine phosphatase receptor type E is a member of the protein tyrosine phosphatase (PTP) family. This family of proteins are known to be signaling PTPRE siRNA Set I molecules that regulate a variety of cellular processes siRNA duplexes targeted against three exon regions including cell growth, differentiation, mitotic cycle, and oncogenic transformation. PTPRE is highly expressed in Catalog # P52-911B brain and testis (1). The regulatory roles of this PTP in Ras Lot # Z2085-30 related signal transduction pathways, cytokines induced Packaging Specifications 2.5 nmol/tube for 3 x 5 nmol signaling, as well as the activation of voltage-gated K+ Format Lyophilized powder channels have been identified. PTPRE has a Stability 1yr at -70oC from date of shipment transmembrane segment and a cytoplasmic region Storage & Shipping The lyophilized powder is stable for at least 4 weeks at room temperature.
