CD45 / LCA Previously Observed Antibody Staining Patterns
Observed Antibody Staining Data By Tissue Type:
Variations in CD45 / LCA antibody staining intensity in immunohistochemistry on tissue sections are present across different anatomical locations. An intense signal was observed in lymphoid tissue in appendix, hematopoietic cells in the bone marrow, germinal center cells in the lymph node, non-germinal center cells in the lymph node, cells in the red pulp in spleen, cells in the white pulp in spleen, germinal center cells in the tonsil and non-germinal center cells in the tonsil. More moderate antibody staining intensity was present in lymphoid tissue in appendix, hematopoietic cells in the bone marrow, germinal center cells in the lymph node, non-germinal center cells in the lymph node, cells in the red pulp in spleen, cells in the white pulp in spleen, germinal center cells in the tonsil and non-germinal center cells in the tonsil. Low, but measureable presence of CD45 / LCA could be seen in. We were unable to detect CD45 / LCA 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.
Observed Antibody Staining Data By Tissue Disease Status:
Tissues from cancer patients, for instance, have their own distinct pattern of CD45 / LCA expression as measured by anti-CD45 / LCA antibody immunohistochemical staining. The average level of expression by tumor is summarized in the table below. The variability row represents patient to patient variability in IHC staining.

| General Description of CD45 / LCA. | |
| Recognizes the CD45 leukocyte common antigen (LCA) family which is comprised of at least four isoforms of membrane glycoproteins (220, 205, 190, 180kDa) expressed on hematopoietic cell lines but absent on non-hematopoietic cell lines, normal, malignant non-hematopoietic tissues. The intracellular portions of these molecules have protein phosphatase activity, are involved in regulation of transmembrane signals. Antibody to CD45 is useful in differential diagnosis of lymphoid tumors from non-hematopoietic undifferentiated neoplasms. A positive result with this MAb is highly indicative of lymphoid or myeloid origin. Certain types of lymphoid neoplasms may lack CD45 (Hodgkin lymphoma, some T-cell lymphomas,, some leukemias) so its absence does not rule out a hematolymphoid tumor. This antibody is expressed almost exclusively by cells of hematopoietic lineage, is present in most benign, malignant lymphocytes as well as plasma cell precursors. | |
