Efalizumab is a man-made form of a protein similar to human antibodies.

A solution to this problem would be to generate human antibodies directly from humans.

In 1988 the first human antibodies were produced in plants.

It has been particularly difficult to get human antibodies.

These cells are then used for the full scale manufacture of the 100% human antibody.

A second possible boon would be to use the mice as factories to produce human antibodies to fight disease.

This shows that the drug is a human monoclonal antibody acting against tumors.

Therefore, the drug is a human monoclonal antibody targeting the immune system.

But that part is then grafted onto the rest of a human antibody.

Now, researchers are starting to produce fully human antibodies.
