ADD1 siRNA Set I(A38-911)
FOR BULK ORDER REQUESTS PLEASE CONTACT US
Description :ADD1 is a pool of three individual synthetic siRNA duplexes designed to knock-down human ADD1 mRNA expression. Each siRNA is 19-25 bases in length.
Specificity :ADD1 siRNAs are designed to specifically knock-down human ADD1 expression.
Formulation :The siRNAs are supplied as a lyophilized powder and shipped at room temperature.
Reconstitution Protocol :Briefly centrifuge the tubes (maximum RCF 4,000g) to collect lyophilized siRNA at the bottom of the tube. Resuspend the siRNA in 50 ul of DEPC-treated water (supplied by researcher), which results in a 1x stock solution (10 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 :alpha-adducin, ADDA, Erythrocyte adducin subunit alpha
Scientific Background :ADD1 or Adducin 1 is a heterodimeric protein associated with the erythrocyte membrane skeleton, which promotes binding of spectrin to actin, and is a substrate for PKC and PKA (1). Alpha- and gamma-adducins are ubiquitously expressed while beta-adducin is expressed at high levels in brain and hematopoietic tissues. ADD1 can completely block elongation and depolymerization at the fast-growing barbed ends of actin filaments in vitro and this suggests that adducin restrict actin filament length in erythrocytes (2).
