The bad news was that very few of the transgenic animals produced anything nearly so tough.

This is in contrast to other groups who showed more limited effects on the immune system of the transgenic animals (67,68).

These will give more consistent levels of protein than do current transgenic animals, he said.

Patent Office officials said they did not impose a formal moratorium on transgenic animals.

The number of transgenic animals typically varies from two to eight.

Scientists are using transgenic animals as a versatile and powerful resource for a wide variety of studies.

Industrialists hope to use transgenic animals to produce valuable drugs and other substances.

A wide range of transgenic animals has already been produced.

The techniques for producing transgenic animals are less than a decade old and still evolving.
