Store at 2 to 8 °C for one week .
Store at -20 to -80 °C for twelve months from the date of receipt.
- 细胞定位：
- Cell membrane ; Single-pass type I membrane protein . Exists primarily an intracellular antigen whose surface expression is tightly regulated by restricted trafficking to the cell surface and rapid internalization.
- 组织表达：
- Widely expressed with highest levels in lymphoid tissues. Detected in activated T-cells where expression levels are 30- to 50-fold less than CD28, the stimulatory coreceptor, on the cell surface following activation.
