Agonist antibodies are disclosed which bind to the extracellular domain of receptor protein tyrosine kinases pTKs and thereby cause, dimerization and activation of the intracellular tyrosine kinase domain thereof. The antibodies are useful for activating their respective receptor and thereby enabling the role of the tyrosine kinase receptor in cell growth and/or differentiation to be studied. Chimeric proteins comprising the extracellular domain of the receptor pTKs and an immunoglobulin constant domain sequence are also disclosed.

Why it's free to use
- Filed April 4, 1995 and granted July 19, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 4, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 4, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
