Scientific Data Images for CD45 Antibody (PSH03-64)
Immunocytochemistry/ Immunofluorescence: CD45 Antibody (PSH03-64) [NBP3-32448]
Immunocytochemistry/ Immunofluorescence: CD45 Antibody (PSH03-64) [NBP3-32448] - Immunocytochemistry analysis of Raji cells labeling CD45 with Mouse anti-CD45 antibody (NBP3-32448) at 1/100 dilution.Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Mouse anti-CD45 antibody (NBP3-32448) at 1/100 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Mouse IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.
beta Tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Rabbit IgG H&L (iFluor™ 594) were used as the secondary antibody at 1/1,000 dilution.
Flow Cytometry: CD45 Antibody (PSH03-64) [NBP3-32448]
Flow Cytometry: CD45 Antibody (PSH03-64) [NBP3-32448] - Flow cytometric analysis of human PBMC labeling human CD45.Cells were washed twice with cold PBS and resuspend. Then stained with the primary antibody (NBP3-32448, 1μg/mL) (red). After incubation of the primary antibody at +4℃ for 30 minutes, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Mouse IgG Secondary antibody at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).

Background: CD45
Given its role in immune cell development and activation, CD45 has also been linked to a variety of diseases. The importance of CD45 in immunity has been revealed in human and mouse studies where CD45-deficiency leads to a severe-combined immunodeficiency (SCID) phenotype (2, 3, 6). A CD45-knockout mice study revealed inhibited thymocyte production and poor B-cell response, whereas CD45 activation in mice causes lymphoproliferation and autoantibody production (3). CD45 variants have been associated with altered immune function and autoimmune disorders including multiple sclerosis, systemic lupus erythematosus (SLE), and rheumatoid arthritis (6). Furthermore, altered CD45 expression has been implicated in oncological conditions including chronic lymphatic leukemia, acute lymphatic leukemia, Hodgkin lymphoma, multiple myeloma, and diffuse large B-cell lymphoma (6). Considering its role in autoimmune disorders, immunodeficiency and cancer, CD45 is an ideal therapeutic target (3, 6). The main approaches to control CD45 function is through either selective inhibitors or anti-CD45 antibodies (3).
Alternative names for CD45 includes B220, CD antigen: CD45, CD45 antigen, CD45R, EC 3.1.3.48, GP180, LCA, Leukocyte common antigen, LY5, protein tyrosine phosphatase receptor type c polypeptide, PTPRC, receptor-type tyrosine-protein phosphatase C, T200 Glycoprotein, and T200.
