The invention relates to a family of substantially pure receptor like TGF-, .beta.1 binding glycoproteins. These molecules are characterized by molecular masses of 160 kd 70-80 kd, and 30-40 kd as , determined by SDS-PAGE and the ability to bind the, TGF-.beta.1 molecule. This family of molecules is useful in identifying and/or quantifying TGF-.beta.1 in a sample, as well as inhibiting its effect on cells.

Why it's free to use
- Filed June 18, 1992 and granted September 17, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 18, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 18, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
