2.4. Functional analysis of leucocytes
Leukocyte functions were determined by evaluating the
capacity to eliminate bacteria, the expression of surface activation
markers and the oxygen radical production.
Buffered Salt Solution (HBSS) tothe desired final concentration. The
granulocyte-containing pellet was suspended in 50 ml ice-cold
isotonic lysis solution for 10e15 min. After centrifugation (400?g,
5 min) the remaining erythrocytes were lysed in fresh lysis solution
for another 5 min. The granulocytes were washed twice with cold
PBS and suspended in HBSS (with 0.5% bovine serum albumin
(BSA)) to the desired final concentration.
