Human peripheral blood lymphocytes were stained with purified CD45 (clone HI30) (filled histogram) or purified mouse IgG1, κ isotype control (open histogram), followed by anti-mouse IgG FITC.
Human peripheral blood lymphocytes were stained with purified CD45 (clone HI30) (filled histogram) or purified mouse IgG1, κ isotype control (open histogram), followed by anti-mouse IgG FITC.
Preparation and staining of formalin fixed paraffin-embedded (FFPE) human tonsil was performed. After antigen retrieval, the sample was incubated with the purified monoclonal antibody (clone HI30) at 0.5 µg/mL for 20 minutes. The Ultra Streptavidin (USA) HRP Detection Kit (Multi-Species, DAB) was used according to protocol for chromogenic detection.
CD45 is a 180-240 kD single chain type I membrane glycoprotein also known as leukocyte common antigen (LCA) and T200. It is a tyrosine phosphatase expressed on the plasma membrane of all hematopoietic cells, except erythrocytes and platelets. CD45 is a signaling molecule that regulates a variety of cellular processes including cell growth, differentiation, cell cycle, and oncogenic transformation. CD45 plays a critical role in T and B cell antigen receptor-mediated activation by dephosphorylating substrates including p56Lck, p59Fyn, and other Src family kinases. CD45 non-covalently associates with lymphocyte phosphatase-associated phosphoprotein (LPAP) on T and B lymphocytes. CD45 has been reported to bind galectin-1 and to be associated with several other cell surface antigens including CD1, CD2, CD3, and CD4.
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per 106 cells in 100 µl volume or 100 µl of whole blood. For immunohistochemical staining on formalin-fixed paraffin-embedded tissue sections, a concentration range of 0.1 - 10 µg/ml is suggested, if the antibody is not available in a pre-diluted format. It is recommended that the reagent be titrated for optimal performance for each application.
Application Notes
Additional reported applications (for the relevant formats) include: immunohistochemical staining of acetone-fixed frozen tissue sections and formalin-fixed paraffin-embedded tissue sections9, inhibition of CD45 functions4, immunofluorescence11, Western blotting3, and spatial biology (IBEX)16,17.
It was found that the HI30 clone and the 2D1 clone can cross block each other's binding.
