Immunohistochemical
characterization of APC and T cells in small MOPC315 tumors.
(A) Staining with anti-CD138 (Syndecan-1) and
anti-class II (I-Ed) and DAPI (nuclei). (B)
Staining with anti-CD11b (Mac-1) and anti-class II. Arrows indicate
clusters of cells that are class II+ CD11b−.
(C) (Left) Staining with anti-CD31 (green)
and anti-CD11b (red). (Right) Two-fold magnification of the
framed field on the left with DAPI-stained nuclei. (D
and E) (Left) Single staining with
TCR-TG- clonotype specific GB113 mAb (brown) of small Id+
MOPC315 (D) or Id− J558 (E)
tumors, with hematoxilin-stained nuclei. (Right)
Five-fold magnifications of framed fields on the left. (F)
Staining with GB113 and Vβ8-specific F23.1 mAbs, and DAPI.
(G) Staining with GB113 and anti-CD11b mAbs.
(H) Staining of tumor sections, from mice given BrdUrd,
with GB113 and anti-BrdUrd mAbs. (I) Staining with GB113
mAb (red), anti-CD31 mAb (green), and DAPI.
