However, this fraction was still contaminated with an additional protein, probably alpha 1 macroglobulin (a1M), which has similar physicochemical properties to [alpha]2M (8,9).
It forms stable complexes with several extracellular protease inhibitors, predominantly al-antichymotrypsin (ACT) and [[alpha].sub.2] macroglobulin ([[alpha].sub.2]M).
In blood, TGF-[beta] supposedly occurs associated mainly with [[alpha].sub.2] macroglobulin ([alpha]2M) [5,6].
