CD21 is a 145 kD transmembrane protein also known as complement C3d receptor (C3dR), complement receptor 2 (CR2), and Epstein-Barr virus receptor. CD21 is expressed on B cells, follicular dendritic cells, subsets of normal thymocytes and T cells, and some epithelial cells. CD21 is the receptor used by Epstein-Barr virus to infect B cells and is also the complement receptor for C3d. CD21 has also been shown to interact with a number of proteins, including CD23, CD19, annexin VI, CD81, iC3b, complement receptor 1 (CR1, CD35), and interferon-alpha 1 (IFN-α1).Product Details

FC - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.
* PerCP/Cyanine5.5 has a maximum absorption of 482 nm and a maximum emission of 690 nm.
- Excitation Laser
Blue Laser (488 nm)
- Application Notes
Additional reported applications (for the relevant formats) include: immunohistochemical staining of acetone-fixed frozen sections4.
- Additional Product Notes
- BioLegend is in the process of converting the name PerCP/Cy5.5 to PerCP/Cyanine5.5. The dye molecule remains the same, so you should expect the same quality and performance from our PerCP/Cyanine5.5 products. Contact Technical Service if you have any questions.

- How stable is PerCP/Cyanine5.5 tandem as compared to PerCP alone?
PerCP/Cyanine5.5 is quite photostable and also better than PerCP alone in withstanding fixation.
