Immunohistochemistry-Paraffin: IRP2 Antibody [TA309703] - IHC analysis of a formalin fixed paraffin-embedded (FFPE) human placenta using 1:300 conc. of IRP2 antibody on a Bond Rx autostainer (Leica Biosystems). The assay involved 30 minutes of heat induced antigen retrieval (HIER) using 10mM sodium citrate buffer (pH 9.0) and endogenous peroxidase quenching with peroxide block. The sections were incubated with primary antibody for 15 minutes and Bond Polymer Refine Detection (Leica Biosystems) with DAB was used for signal development followed by counterstaining with hematoxylin. Cytoplasmic staining was observed in villi of endothelial cells.
