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 -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
