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.
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 :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.
