transgenic contraceptive plants



The patent below is for plants used to make potent contraceptives.After the
most recent fiasco where genes for pig virus antigen got mixed in corn and soy
FDA may get a real giggle our of spreading the contraceptive in midwestern
USA.On the other hand the regulators may prefer to test such
biopharmaceuticals in an unimporant isolated place such as Canada. In Canada
dangerous biopharmaceuticals are tested with great secrecy and the public are
not allowed to know what hit them.
We must insure that we will  beinformed of future biopharmaceutical crop
testing.

The present invention provides for processing methods that preserve
pharmaceutical proteins expressed in plants. Herein raw plant tissue is
reduced to a stable homogenate without significant loss of protein or
pharmaceutical potency. The homogenate can be used directly for pharmaceutical
purposes without the need to further extract, purify, or precipitate the
pharmaceutical protein. The present invention further provides a method of
effective immunocontraception for animal and human application. Methods are
disclosed for producing transgenic plant or plant cells which express
contraceptive proteins, and which can be delivered whole, in part, or after
processing, to an animal to cause a contraceptive effect in the target
species.
