| Decay Accelerating Factor (or CD55) is a major regulator of the alternative and classical pathways of complement activation and is expressed on all serum-exposed cells. It is commonly hijacked by invading pathogens, including many enteroviruses and uropathogenic Escherichia coli, to promote cellular attachment prior to infection. |
| Recombinant Human CD55 Protein is expressed from Expi293 with His tag at the C-terminal. It contains Asp35-Ser353. |
