Thin sections were cut using an ultramicrotome (Leica Microsystems, Germany), and the sections were subjected to double staining with uranyl acetate and lead citrate and then observed using a transmission electron microscope (Hitachi HT7800, Japan)
In addition to phagocytosis, they can secrete bactericidal granule contents after direct activation by the pathogen, either by cytolysis, exocytosis, or piecemeal degranulation (36)
A number of factors contribute: Different manufacturers use different stabilization/packaging processes (e.g., presence of excipients, vacuum sealing, desiccants)
