Phenotypic characterization of tetrameric Mamu-A*01/p11C, C-M complex-binding CD8αβ+ T cells. A whole-blood specimen (PBL) and a single-cell suspension of lymph node lymphocytes (LN) from the Mamu-A*01+, SIVmac-infected rhesus monkey 138 were stained with Alexa 488-coupled tetrameric Mamu-A*01/p11C, C-M complex and four different PE-coupled MAbs (anti-CD28, anti-CD45RA, anti-CD62L, and anti-HLA-DR). Percentages of cells in the different quadrants are indicated.
