This antibody recognises the human CD59 cell surface antigen, an 18-20 kDa GPI linked glycoprotein broadly expressed by human leucocytes and erythrocytes. Clone YTH53.1 has been shown to block the normal function of CD59. Removal of sodium azide is recommended prior to use in functional assays. CD59 is expressed by erythrocytes, and therefore staining in whole blood systems requires a higher concentration of antibody.
纯化方法
Purified IgG prepared by affinity chromatography on Protein G from tissue culture supernatant
免疫原
Human Peripheral Blood T cells. Spleen cells from an immunised DA rat were fused with cells of the Y3/Ag1.2.3 rat myeloma line.
Western Blot. Flow Cytometry: Use 10 μL of 1/50-1/100 diluted antibody to label 10^6 cells in 100 μL. Immunohistochemistry on Frozen Sections. Immunohistochemistry on Paraffin Sections (1/5-1/10): This product requires antigen retrieval using heat treatment prior to staining of paraffin sections. Sodium citrate buffer pH 6.0 is recommended for this purpose. Positive Control Tissue: Placenta. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

CD59, an LY6 like protein expressed in human lymphoid cells, regulates the action of the complement membrane attack complex on homologous cells. It is a potent inhibitor of the complement membrane attack complex action. It acts by binding to the C8 and/or C9 complements of the membrane attack complex, thereby preventing incorporation of the multiple copies of C9 required for complete formation of the osmolytic pore. This inhibitor appears to be species-specific. CD59 is also involved in signal transduction for T-cell activation complexed to a protein tyrosine kinase.Synonyms: 20 kDa homologous restriction factor, HRF-20, HRF20, MAC-IP, MAC-inhibitory protein, MACIF, MEM43 antigen, MIC11, MIN1, MIN2, MIN3, MIRL, MSK21, Membrane attack complex inhibition factor, Membrane inhibitor of reactive lysis, Protectin
