Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Cytokeratin 19 antibody [LP2K] - BSA and Azide free (AB255939)

This data was developed using ab254186, the same antibody clone in a different buffer formulation.

Immunohistochemical analysis of paraffin-embedded human lung carcinoma tissue labeling Cytokeratin 19 with ab254186 at 1/10000 (0.105 μg/ml) dilution followed by ready to use LeicaDS9800 (Bond™ Polymer Refine Detection). Membranous staining on human lung carcinoma is observed. The section was incubated with ab254186 for 30 mins at room temperature and followed by specific mouse IgG antibody (ab190482) for 8mins. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument. Counterstained with Hematoxylin.

Secondary antibody only control : Secondary antibody is ready to use LeicaDS9800 (Bond™ Polymer Refine Detection).

Heat mediated antigen retrieval with Citrate buffer (pH 6.0, epitope retrieval solution 1) for 20 mins.
