Question
Protein A, which has strong affinity to Fc region of immunoglobulin, is extracted from
The correct answer is
Staphylococcus aureus
Source of Protein A
Protein A is a surface protein component found in certain bacteria. It is well-known for its specific ability to bind to the Fc region of immunoglobulin G (IgG) molecules from various species.
Extraction Details
- The question asks for the organism from which Protein A is extracted.
- Protein A's strong affinity for the Fc region of immunoglobulins is a key characteristic.
- Among the given options, Staphylococcus aureus is the bacterium known to naturally produce Protein A.
- This protein is widely used in biotechnology and research for purifying antibodies.
Therefore, Protein A is extracted from Staphylococcus aureus.
