| Reference Data | |
| UniProt ID | P38507 |
| Synonyms | ProA, Staphylococcus A protein |
| Summary | Protein A is a surface protein (approximately 56kDa in size) originally discovered within the cell wall of Staphylococcus aureus. While important for bacterial survival, Protein A has beneficial uses in immunology for its high affinity binding to immunoglobulins (especially the IgG isotype). This high affinity property makes Protein A essential in the large scale purification of antibodies. |
| Protein Families | as a control or standard in assays, for conjugation and most other immunological methods., Suitable for use as antigen |
