What is the Difference Between Convalescent Plasma and Monoclonal Antibodies?
🆚 Go to Comparative Table 🆚Convalescent plasma and monoclonal antibodies are both antibody-based therapies used to treat COVID-19, but they differ in their production and composition.
Convalescent Plasma:
- Derived from people who have recovered from COVID-19 and donated their plasma.
- Contains a mixture of various antibodies, including those that target the virus.
- The antibody content in convalescent plasma may vary depending on the donor and the specific sample.
- Studies have shown that early treatment with convalescent plasma can reduce mortality in high-risk patients.
Monoclonal Antibodies:
- Manufactured in a laboratory.
- Target a specific antigen, which is a protein or molecule associated with the virus.
- Contain a single, cloned antibody that is designed to bind to a specific antigen.
- Monoclonal antibodies with high antibody content have been shown to improve patient outcomes.
In summary, convalescent plasma is derived from the plasma of recovered COVID-19 patients, while monoclonal antibodies are laboratory-produced antibodies that target specific antigens. Both therapies have shown potential in treating COVID-19, but their effectiveness may vary depending on factors such as the timing of administration and the specific antibody content.
Comparative Table: Convalescent Plasma vs Monoclonal Antibodies
Here is a table highlighting the differences between convalescent plasma and monoclonal antibodies:
Characteristic | Convalescent Plasma | Monoclonal Antibodies |
---|---|---|
Definition | Convalescent plasma therapy is a type of treatment in which the blood plasma of one person who has recovered from an infection is used to treat another individual with the same infection. | Monoclonal antibodies are proteins made in a laboratory to treat specific infections. |
Formation | Convalescent plasma is made in the person's body and then extracted and put through plasmapheresis. | Monoclonal antibodies are made in a laboratory by first injecting antigens into a mouse and then synthesizing and cloning them. |
Variability | Convalescent plasma varies because immune system responses vary. | Monoclonal antibodies do not vary as they are synthesized and cloned in the laboratory. |
Advantages | An advantage of convalescent plasma therapy is that it works well for many viruses and is inexpensive. | Examples: Covid-19 plasma has been taken from patients who have been ill and recovered, and used to treat severely ill Covid-19 patients. |
Disadvantages | Although rare, there are some potential dangers associated with convalescent plasma therapy, such as allergic responses and lung damage. |
Both convalescent plasma and monoclonal antibodies are antibody-based therapies, but they differ in how they are made and their variability.
