Activin Receptor Type IIB (RIIB)
Description:
Members of the TGF-beta superfamily exert their biological effects by binding to heteromeric complexes of a type I and a type II serine-threonine kinase receptor, both of which are essential for signal transduction. Activin receptor type IIB is a type II receptor that mediates multiple signals for transforming growth factor-beta (TGF-beta) family members, including Activin, Nodal, BMP-7, GDF-1, GDF-3, Myostatin (GDF-8), and GDF-11. Through alternative mRNA splicing, multiple ActR-IIB isoforms can also be generated.

Applications:
Suitable for use in Direct ELISA and Western Blot. Other applications not tested.

Recommended Dilutions:
Direct ELISA: 0.5-1.0ug/ml. The detection limit for recombinant human Activin RIIB is ~2ng/well.
Western Blot: 1-2ug/ml. The detection limit for recombinant human Activin RIIB is ~20ng/lane under reducing and non-reducing conditions.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months after receipt at -20C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20C. Reconstituted product is stable for 12 months at -20C. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
