Platelets / thrombocytes: concentration: 300,000 cells / l. Clot blood; signal coagulation proteins to target the clotted areas. Plasma / serum: 50-60% of blood volume; coagulants, proteins, lipids, etc. dissolved in solution. Somatostatin gene: first replicated in e. coli; codes for production of human growth hormone. Length of time for a biotechnology product to move through all testing and trial phases: 10-15 years. Pulmozyne: enzyme that treats cystic fibrosis; around 3000 children per year are born with cf.
