| Background Information | CD45RA (Leu18) is a high molecular weight isoform of a receptor-type protein tyrosine phosphatase, CD45 glycoprotein. CD45 is crucial in lymphocyte development and antigen signaling, serving as an important regulator of Src-family kinases, promotes cell survival by modulating integrin-mediated signal transduction pathway and is also involved in DNA fragmentation during apoptosis. CD45 isoforms differ in their extracellular domains, whereas they share identical transmembrane and cytoplasmic domains. These isoforms differ in their ability to translocate into the glycosphingolipid-enriched membrane domains and their expression depends on cell type and physiological state of the cell. CD45RA is expressed e.g. on naive T cells and normal plasma cells. |
| Usage | The reagent is designed for indirect immunofluorescence analysis by Flow Cytometry. Suggested working usage is 8.3·µg/ml. Indicated dilution is recommended starting point for use of this product, but working concentrations should be validated by the investigator. |
| Storage Buffer | The reagent is provided in Tris buffered saline (TBS) solution, pH ≈8.0, 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. |
