Study Notes
Monoclonal Antibodies
- Restricted to mouse cells
- Can be developed and grown in cell culture, which is quick and inexpensive
- Provides a lifelong source of antibodies with minimal purification needed
- Most commonly used in immunoassays
- Offers a constant source of antibodies
Polyclonal Antibodies
- Can be obtained from various animal species, as long as they are large enough
- Requires animal housing and strict regulations
- Provides a finite source of antibodies, as the animal will eventually die of old age
- The antibody source changes each time a new animal is used
- Requires purification of antibodies from other cell components
- Best suited for large antigens with changing epitopes, such as bacteria
