This detailed volume is devoted to the recent development of quantitative experiments and computational methods driving new transforming growth factor beta (TGF- ) and other cell signaling knowledge. Many chapters cover quantitative assays for TGF- signaling studies, with others exploring the increasing role of both modeling and computational methods. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, TGF-Beta Signaling: Methods and Protocols serves as a vital resource for researchers seeking to move the TGF- field into the quantitative realm.
