Insulin Discovery & How It’s Made Today (Recombinant Technology)
🩺 “Insulin is one of the most important discoveries in medical history — and today, it is produced using advanced biotechnology for better safety and effectiveness.”
✨ Discovery of Insulin
In 1921, scientists discovered insulin as a life-saving treatment for diabetes.
Earlier, insulin was extracted from animal sources like pigs and cows.
This helped save millions of lives — but had limitations.
✨ Old Method — Animal Extraction
🐖 Insulin was taken from animal pancreas
⚠️ Risk of allergic reactions
⚠️ Variation in purity
⚠️ Limited supply
✨ Modern Method — Recombinant Technology
🧬 Human insulin is produced using genetic engineering
🔬 Scientists insert the human insulin gene into bacteria or yeast
🧪 These cells produce insulin identical to human insulin
✨ Why Recombinant Insulin Is Better
✔ Highly pure and safe
✔ Reduced risk of allergic reactions
✔ Consistent quality
✔ Large-scale production possible
💡 Kiran Multi Speciality Hospital Advice:
Modern insulin therapy is safe, effective, and life-saving when used correctly under medical supervision.
Advances in science continue to improve diabetes care and patient outcomes.
