CD8a is a 32-34 kD type I glycoprotein. It forms a homodimer (CD8a/a) or heterodimer (CD8a/b) with CD8b. CD8, also known as T8 and Leu2, is a member of the immunoglobulin superfamily found on the majority of thymocytes, a subset of peripheral blood T cells, and NK cells (which express almost exclusively CD8a homodimers). CD8 acts as a co-receptor with MHC class I-restricted T cell receptors in antigen recognition and T cell activation and has been shown to play a role in thymic differentiation. Two domains in CD8a are important for function: the extracellular IgSF domain binds the α3 domain of MHC class I and the cytoplasmic CXCP motif binds the tyrosine kinase p56 Lck.Product Details

- Antibody Type
- Host Species
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)
- The antibody was purified by affinity chromatography, and conjugated with PerCP/Cyanine5.5 under optimal conditions.
- Lot-specific (to obtain lot-specific concentration, please enter the lot number in our Concentration and Expiration Lookup or Certificate of Analysis online tools.)
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
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.
- Application Notes
Clone HIT8a recognizes the alpha chain of CD85. It does not block the binding of RPA-T8 antibody to CD8a.
Additional reported applications of this antibody (for the relevant formats) include: immunohistochemical staining of acetone-fixed frozen tissue sections5,6. This clone was tested in-house and does not work on formalin fixed paraffin-embedded (FFPE) tissue.
- 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.
