Significance of human insulin 1978: insulin from animal; pig and cow Switch to microbial culture. Why?

Quantity & quality is better No allergy and side effect

E. coli culture is convenient Cheaper for commercial

Predictable Problems easily solved

Conclusion Insulin market grown at

7% annual rate Company: Novo

Nordisk, Eli Lilly & Sanofi Aventis

Cost : £75 – 200 per vial Different delivery ways
