Immunohistochemical analysis of paraffin-embedded human liver tissue using anti-Lactate Dehydrogenase antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes.The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH₂O and PBS, and then probed with the primary antibody (ET1608-57, 1/50) for 30 minutes at room temperature.
