Abstract
Methods for recovering t-PA from a liquid medium are disclosed. The methods comprise contacting a liquid medium with at least one substrate capable of effecting a separation of intact t-PA from degraded t-PA thereafter recovering the intact t-PA free from other unrelated protein. The present invention also provides compounds produced by this method, compounds comprising intact one-chain t-PA and pharmaceutical compositions containing them and methods for using such compositions.
