Uses
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project
(www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. To view these

General Description
Decay accelerating factor (DAF)/complement decay-accelerating factor (CD55) is a cell associated C3 and C5 convertase regulator made of 4 tandem repeats (~60 amino acid long) known as short consensus repeats (SCRs) or complement control repeats (CCPs). It is a glycosylphosphatidylinositol (GPI)-anchored protein widely scattered among hematopoietic and nonhematopoietic cells. CD55 is located on human chromosome 1.
Biochem/physiol Actions
Decay accelerating factor (DAF)/complement decay-accelerating factor (CD55) regulates adaptive T cell responses. It serves as a receptor for the invasion of human RBCs by malaria parasites. It modulates the complement cascade on the cell surface. It also transfers the antigen determinants for the Cromer blood group system (CROM).
