Spleens were then treated with
ACK lysis buffer to remove RBCs.
Spleens were processed into cell suspensions through a 70 - μm strainer by a syringe plunger in RPMI 1640 with 10 % FBS and then treated with
ACK lysis buffer to remove RBCs.
Peripheral blood mononuclear cells were isolated by centrifugation with 96 % Ficoll (BD), followed by erythrocyte lysis with
ACK lysis buffer.
