Immunohistochemical analysis of pulmonary microemboli.
WT mice were injected with the standard preparation of unlabeled microparticles. The lungs were harvested 10 minutes later, washed, fixed, and incubated with (A-C) a murine antihuman fibrin-specific antibody or (D) a nonimmune IgG1 control and enzyme-conjugated secondary antibody (original magnifications × 200).
