What Are Recombinant Proteins?
Recombinant proteins are proteins produced through genetic engineering techniques, where a gene encoding a desired protein is inserted into an expression system (bacterial, yeast, insect, or mammalian cells).
These proteins are widely used in:
- Therapeutics (e.g., insulin, growth hormones, monoclonal antibodies)
- Vaccines (e.g., hepatitis B, HPV)
- Diagnostics (e.g., ELISA, Western blot, molecular assays)
- Research applications (e.g., cell signaling, enzyme assays, structural biology)
Recombinant technology enables consistent quality, scalability, and customized protein expression, transforming biopharma and academic research.
