| Background Information | CD55 (DAF; decay-accelerating factor) is a GPI-anchored membrane glycoprotein that protects autologous cells from classical and alternative pathway of complement cascade. Bidirectional interactions between CD55 and CD97 are involved in T cell regulation and CD55 can still regulate complement when bound to CD97. In tumors, besides protection agains complement, CD55 promotes neoangiogenesis, tumorigenesis, invasiveness and evasion of apoptosis. |
| Usage | The reagent is designed for Flow Cytometry analysis of human blood cells. Recommended usage is 20·µl reagent·/ 100·µl of whole blood or 10^6 cells in a suspension. The content of a vial (2 ml) is sufficient for 100 tests. |
| Storage Buffer | The reagent is provided in stabilizing phosphate buffered saline (PBS) solution, pH ≈7.4, containing 0.09% (w/v) sodium azide. |
| Storage | Avoid prolonged exposure to light. Store in the dark at 2-8°C. Do not freeze. |
| Stability | Do not use after expiration date stamped on vial label. |
