In indicated experiments, they were given 2 injections, 2 days apart, and killed 24 h after the last injection.

Bone marrow transplantation:

… Chimeric mice were injected with PTX 2 months after transplantation.

EAE induction by active immunization:

Mice were subcutaneously injected into both flanks with a total of 200 µl of emulsion containing 300 µg of MOG peptide 3555 (Feldan) dissolved in saline and mixed with an equal volume of complete Freund’s adjuvant containing 500 µg of killed Mycobacterium tuberculosis H37 RA (Difco Laboratories).
