PDE6B siRNA Set I siRNA duplexes targeted against three exon regions

Catalog # P94-911C

Lot # Z2073-2

Specificity Formulation PDE6B siRNAs are designed to specifically knock-down The siRNAs are supplied as a lyophilized powder and human PDE6B expression. shipped at room temperature.

Product Description Reconstitution Protocol PDE6B siRNA is a pool of three individual synthetic siRNA Briefly centrifuge the tubes (maximum RCF 4,000g) to duplexes designed to knock-down human PDE6B 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_000283. (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 rd1; PDEB; RP40; CSNB3 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 PDE6A, Active P94-31G below -20oC. After resuspension, siRNA stock solutions ≥2 PDE6B, Active P94-30BG µM can undergo up to 50 freeze-thaw cycles without PDE6C Protein P94-34CG significant degradation. For long-term storage, it is recommended that the siRNA is stored at -70oC. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.

Scientific Background PDE6B is a member of the phosphodiesterase family of PDE6B siRNA Set I proteins that play a critical role in regulating intracellular siRNA duplexes targeted against three exon regions levels of cAMP and cGMP. PDE6B is a high-affinity cGMP- specific PDE that shows high expression in the eye.
