Immunohistochemistry data from FFPE human tonsil stained with CD40 monoclonal antibody clone C40/2383.
Immunohistochemistry data from FFPE human tonsil stained with CD40 monoclonal antibody clone C40/2383.Analysis of Protein Array containing more than 19,000 full-length human proteins using CD40 Mouse Recombinant Monoclonal Antibody (C40/2383) Z- and S- Score: The Z-score represents the strength of a signal that a monoclonal antibody (MAb) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SD’s) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD’s) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target.  A MAb is considered to specific to its intended target, if the MAb has an S-score of at least 2.5. For example, if a MAb binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that MAb to protein X is equal to 29.SDS-PAGE Analysis Purified CD40 Mouse Monoclonal Antibody (C40/2383).Confirmation of Integrity and Purity of Antibody.

General Description of CD40 / TNFRSF5 / CD40L-Receptor.
CD40 is a receptor on antigen-presenting cells of the immune system and is essential for mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. AT-hook transcription factor AKNA is reported to coordinately regulate the expression of this receptor and its ligand, which may be important for homotypic cell interactions. Adaptor protein TNFR2 interacts with this receptor and serves as a mediator of the signal transduction. The interaction of this receptor and its ligand is found to be necessary for amyloid-beta-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis. CD40 is expressed on B-lymphocytes, follicular dendritic cells, bone marrow-derived dendritic cells, thymic epithelium, and interdigitating cells in the T-cell zones of secondary lymphoid organs.

CD40 / TNFRSF5 / CD40L-Receptor Previously Observed Antibody Staining Patterns

Observed Antibody Staining Data By Tissue Type:

Variations in CD40 / TNFRSF5 antibody staining intensity in immunohistochemistry on tissue sections are present across different anatomical locations. An intense signal was observed in cells in the white pulp in spleen and germinal center cells in the lymph node and tonsil. More moderate antibody staining intensity was present in cells in the white pulp in spleen and germinal center cells in the lymph node and tonsil. Low, but measureable presence of CD40 / TNFRSF5 could be seen inlymphoid tissue in appendix and macrophages in lung. We were unable to detect CD40 / TNFRSF5 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 CD40 / TNFRSF5 expression as measured by anti-CD40 / TNFRSF5 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.
