Abstract
This is a protocol used to perform immunophenotyping of whole blood (collected in EDTA tubes) or cells from bronchoalveolar lavage (BAL). We have successfully used this protocol for rhesus macaques, cynomolgus macaques, and African green monkeys (although antibody mix provided was titrated on AGM only). It allows the characterization of T cells (CD69/CD25 for activation; CCR7/CD45RA for memory phenotype; α/β vs γ/δ ), B cells, Monocytes, Neutrophils, Basophils, Eosinophils, an potentially NK cells (CD56 does not work for AGM).
This protocol was designed to deal with samples coming from containment labs (> CL2) at our facility. If you are using this protocol at a different facility please ensure that proper testing and approvals are in place. The protocol can be used for experiments completed entirely in CL2, simply go from step 17 directly to 31.
Guidelines
For BAL fluid, make sure to set FSC voltage much lower than for whole blood.

Before start
The antibody mix described in the methods was tested on African green monkey whole blood and BAL fluid. CD56 does not stain AGM NK cells. All antibodies should cross-react with cynomolgus and rhesus macaques but the panel might need to be re-titrated.
