CD55 antibody | 67
Mouse anti Human CD55 antibody, clone 67 (MCA1614) used for the identification of CD55 expressing cells in rheumatoid arthritis synovial tissue by immunohistochemistry on cryostat sections.
Image caption:
Representative double staining of rheumatoid arthritis synovial tissue with antibodies against RasGRF1 and cell-specific markers. Synovial tissue sections were stained overnight with antibodies against Ras guanine nucleotide-releasing factor 1(RasGRF1), followed by antibodies against CD3, CD55, and CD68. After biotin tyramide enhancement, staining was developed with amino-ethylcarbazole (red, RasGRF1) and Fast blue (blue, cell-specific markers). Magnification x 100.

Antibody Quality and Performance Guarantee
| Mouse anti Human CD55 antibody, clone 67 recognizes the human CD55 cell surface antigen, a GPI linked molecule also known as decay accelerating factor (DAF). CD55 is expressed by a wide range of cell types. CD55 is the complement regulatory protein, decay accelerating factor (DAF) (Lublin and Atkinson 1989). Human CD55 is a ~70 kDa glycoprotein (in erythrocytes) anchored in the membrane by glycosylphosphatidylinositol tail. In other cells the apparent molecular weight is somewhat larger. It has a substantial content of O-glycans, and also on N-glycan. DAF binds to activated C4b or C3b complement fragments on the cell surface, preventing the assembly and accelerating the decay of both classical and alternative pathways. DAF carries the DAF has a wide distribution on cells in non-haematopoietic tissues, particularly epithelium and is found at the fetal-maternal interface in placenta (Holmes et al. 1990 and Yang et al. 2009). Soluble forms of DAF are found, for example, in plasma, saliva and urine ( |
