ACVR2B siRNA Set I(A36-911)
FOR BULK ORDER REQUESTS PLEASE CONTACT US
Description :ACVR2B is a pool of three individual synthetic siRNA duplexes designed to knock-down human ACVR2B mRNA expression. Each siRNA is 19-25 bases in length.
Specificity :ACVR2B siRNAs are designed to specifically knock-down human ACVR2B 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 :ActR-IIB; ACTRIIB; MGC116908
Scientific Background :ACVR2B or activin A receptor, type IIB is belong to the transforming growth factor-beta (TGF-beta) superfamily of structurally related signaling proteins that signal through a heteromeric complex of receptor serine kinases which include at least two type I (I and IB) and two type II (II and IIB) receptors (1). ACVR2B is help to regulate muscle growth (2). ACVR2B is a transmembrane protein that composed of a ligand-binding extracellular domain with cysteine-rich region, a transmembrane domain, and a cytoplasmic domain with predicted serine/threonine specificity.
