Annexin 5 siRNA Set I(A61-911)

  • $655.00


Description :Annexin 5 is a pool of three individual synthetic siRNA duplexes designed to knock-down human Annexin 5 mRNA expression. Each siRNA is 19-25 bases in length.

Specificity :Annexin 5 siRNAs are designed to specifically knock-down human Annexin 5 expression.

Reconstitution Protocol :Each siRNA duplex is supplied as 2.5nmol per tube (for example 6 x 2.5nmol = 3 x 5nmol per duplex). Briefly centrifuge one tube per duplex (maximum RCF 4,000g) to collect lyophilized siRNA at the bottom of the tube. Resuspend each 2.5nmol tube in 50 ul of DEPC-treated water (included in kit), which results in a 1x stock solution (50 uM). Gently pipet the solution 3-5 times to mix and avoid the introduction of bubbles. Optional: aliquot 1x stock solutions for storage.

Storage and Stability :The lyophilized powder is stable for at least 4 weeks at room temperature. It is recommended that the lyophilized and resuspended siRNAs are stored at or below -20oC. After resuspension, siRNA stock solutions ≥2 uM can undergo up to 50 freeze-thaw cycles without 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.

Format :Lyophilized powder

Gene Aliases :ANXA5, PP4, ANX5, ENX2

Scientific Background :Annexin 5 is a member of the annexin family of calcium-dependent phospholipid binding proteins. Annexin 5 is a phospholipase A2 and protein kinase C inhibitory protein with calcium channel activity and a potential role in cellular signal transduction, inflammation, growth and differentiation. In vitro studies have shown that Annexin 5 is a cellular protein which plays a role in the inhibition of blood coagulation by competing for phosphatidylserine binding sites with prothrombin (1). Through affinity assays Annexin 5 has been localized on cells that expressed phosphatidylserine on the cell surface, a feature found in apoptosis as well as other forms of cell death (2).
