1.   For example, scientists in Denmark have isolated a protein that may fight diabetes .

2.   He also developed a glaucoma treatment and isolated a protein that helped the Navy fight fires in World War II.

3.   In the earlier days of genetic research, scientists generally isolated a protein and worked backward toward the gene that generated it to find disease-causing genes.

4.   The second tissue is the lymphoma, which is removed by a biopsy and from which researchers isolate a protein from the surface of the cancerous cells.

5.   Five years later, he and his team succeeded in isolating the protein that creates the caffeine gene.

6.   The researchers then spent two years isolating other proteins in urine and testing them against HIV.

7.   The scientists isolated a protein, called lysozyme, and found that it was able to kill the AIDS virus quickly in test-tube experiments.
