PTPN7 siRNA Set I siRNA duplexes targeted against three exon regions

Catalog # P34-911

Lot # Z2085-26

Specificity Formulation PTPN7 siRNAs are designed to specifically knock-down The siRNAs are supplied as a lyophilized powder and human PTPN7 expression. shipped at room temperature.

Product Description Reconstitution Protocol PTPN7 siRNA is a pool of three individual synthetic siRNA Briefly centrifuge the tubes (maximum RCF 4,000g) to duplexes designed to knock-down human PTPN7 mRNA collect lyophilized siRNA at the bottom of the tube. expression. Each siRNA is 19-25 bases in length. The Resuspend the siRNA in 50 µl of DEPC-treated water accession number is NM_002832. (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 LC-PTP, LPTP, HEPTP, PTPNI, BPTP-4. 1x stock solutions for storage.

Storage and Stability Related Products The lyophilized powder is stable for at least 4 weeks at room temperature. It is recommended that the Product Name Catalog Number lyophilized and resuspended siRNAs are stored at or PTPN1 (PTP1B), Active P28-20G below -20oC. After resuspension, siRNA stock solutions ≥2 PTPN11 (SHP2), Active P38-21G µM can undergo up to 50 freeze-thaw cycles without PTPN12 (PTP-PEST), Active P39-21G significant degradation. For long-term storage, it is PTPN13 (FAP-1), Active P40-21G recommended that the siRNA is stored at -70oC. For most PTPN2 (TC-PTP), Active P29-20G favorable performance, avoid repeated handling and PTPN6 (SHP1), Active P33-20G multiple freeze/thaw cycles. PTPN7 (LC-PTP), Active P34-20G Anti-PTPN11 (SHP2) P38-63CR Scientific Background Anti-PTPN11 (SHP2) P38-63BR PTPN7 gene is preferentially expressed in a variety of hematopoietic cells, and is an early response gene in lymphokine stimulated cells (1). The noncatalytic N- terminus of this PTP can interact with MAP kinases and PTPN7 siRNA Set I siRNA duplexes targeted against three exon regions negatively regulates ERK2 and p38 MAP-kinases activity (2). The PTPN7 was shown to be involved in the regulation Catalog # P34-911 of T cell antigen receptor (TCR) signaling, which was Lot # Z2085-26 thought to function through dephosphorylating the Packaging Specifications 2.5 nmol/tube for 3 x 5 nmol molecules related to MAP kinase pathway (3).
