Abstract
Thromboapondin 1 (TSP-1) is a trimeric matricellular protein that is expressed by many cells. It contains several different domains that allow it to participate in cell adhesion, cell migration, and cell signaling. Recently TSP-1 has been shown to activate transforming growth factor beta (TGF-beta) and to inhibit both angiogenesis and tumor growth. This unit contains protocols for the purification of TSP-1 from platelet-rich plasma and the purification of TSP-1 proteolytic fragments.
