CD19 Previously Observed Antibody Staining Patterns
Observed Antibody Staining Data By Tissue Type:Variations in CD19 / Leu-12 antibody staining intensity in immunohistochemistry on tissue sections are present across different anatomical locations. An intense signal was observed in cells in the red pulp in spleen, cells in the white pulp in spleen, germinal center cells in the lymph node and tonsil, lymphoid tissue in appendix and non-germinal center cells in the lymph node and tonsil. More moderate antibody staining intensity was present in cells in the red pulp in spleen, cells in the white pulp in spleen, germinal center cells in the lymph node and tonsil, lymphoid tissue in appendix and non-germinal center cells in the lymph node and tonsil. Low, but measureable presence of CD19 / Leu-12 could be seen in. We were unable to detect CD19 / Leu-12 in other tissues. Disease states, inflammation, and other physiological changes can have a substantial impact on antibody staining patterns. These measurements were all taken in tissues deemed normal or from patients without known disease.
