Biotechnology & Its Applications: Real-World & Industry Applications

Humulin (recombinant insulin) — produced by Eli Lilly using E. coli; first biotechnology product for diabetes treatment; eliminated dependence on pig/cattle pancreas extracts
ADA gene therapy — first human gene therapy success; model for treating SCID; paved the way for CAR-T cell therapy and other retroviral vector approaches
PCR in forensics and medicine — HIV diagnosis, genetic disorder carrier testing, prenatal diagnosis, forensic DNA fingerprinting
ELISA in public health — blood bank screening for HIV and hepatitis B; pregnancy test kits; food safety testing for toxins and allergens
Bt cotton — reduced pesticide use in Indian and global cotton farming by 70–80% after adoption; reduces environmental chemical load and farmer costs
Bt corn — protection against European corn borer reduces post-harvest losses and mycotoxin contamination (fungi that colonize insect-damaged kernels)
RNAi technology — potential for species-specific pest control without chemicals; also used in cancer therapy research and functional genomics
Golden Rice — humanitarian initiative to reduce vitamin A deficiency-related blindness in children; estimated 250 million children at risk globally
Flavr Savr tomato — demonstrated commercial viability of GM food; though withdrawn from market due to taste and logistic issues, it opened regulatory pathways
Alpha-1-antitrypsin from transgenic sheep — treatment for hereditary emphysema; alternative to plasma-derived protein, which carries infection risk
Transgenic mice as disease models — oncomouse (first patented animal) used for cancer drug screening; reduced dependence on expensive primate models
GEAC regulation — ensures environmental risk assessment before GM crop field trials; protects Indian biodiversity and farmer interests
Biopiracy prevention (CBD + Nagoya Protocol) — India's Biological Diversity Act 2002 protects indigenous knowledge; traditional knowledge digital library (TKDL) documents prior art to prevent future biopiracy
