Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-MASP2 antibody [EPR23588-44] (AB277520)

Immunohistochemical analysis of paraffin-embedded human colon tissue labeling MASP2 with ab277520 at 1/500 dilution, followed by Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Positive staining on plasma of human colon (PMID : 32771488). Counter stained with Hematoxylin. The section was incubated with ab277520 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument

Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is Rabbit specific IHC polymer detection kit HRP/DAB (ab209101).

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.

Multiplex immunohistochemistry - Anti-MASP2 antibody [EPR23588-44] (AB277520)

Fluorescence multiplex immunohistochemical analysis of human liver (formalin-fixed paraffin-embedded section). Panel A shows merged staining of anti-MASP2 stained on cytoplasm of hepatocytes (ab277520; gray; Opal™690) at 1 : 100 ( 5.22 μg/ml) [Panel B] , anti-CD163 stained on Kupffer cells (ab213612; green; Opal™520) at 1 : 8000 ( 0.13 μg/ml) [Panel C], and anti-eNOS tained on endothelial cells (ab252439; red; Opal™570) at 1 : 200 ( 3.005 μg/ml) [Panel D] on human liver. DAPI was used as a nuclear counter stain. Followed by Opal Polymer HRP Ms + Rb secondary. The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope. The section was incubated in three rounds of staining : in the order of ab277520, ab213612, and ab252439 for 30 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins was used.
