Figure Lengend Snippet: Figure 3. The effect of 0.8% of natural humic substances prepared from leonardite in feed on the per- centage of CD4+ CD8–, CD8+ CD4– and CD4+ CD8+ lymphocytes in broiler peripheral blood. Means with different superscripts are significantly different **p < .01.
Article Snippet: Tubes were centrifuged for 30 min at 600× g. MNL were recovered by aspirating white layer in plasma-LSM interphase, and the acquired sample was washed twice with PBS by centrifugation for 5 min at 250× g. Selected lymphocyte subpopulations were identified by direct staining with a subsequent combination of conjugated anti-chicken monoclonal antibodies (MoAb): CD4-FITC/ CD8a-R-PE/CD45-APC (Southern Biotech, USA).
