CD55, a widely-distributed a 70kDa phosphatidyl inositol-anchored protein, acts as a complement regulatory protein. It is expressed in wide range of cells such as normal tissues, body fluids and stroma along with several cancerous cells such as colorectal cancer.
Synonyms: Anti-CD55 antigen antibody produced in rabbit; Anti-Complement decay-accelerating factor precursor antibody produced in rabbit

Application: 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.

Biochem Physiol Actions: CD55 is involved in the complement-mediated cell lysis. It triggers proliferation of human peripheral T cells. It mainly helps in dissociating C3/C5 convertases as well as preventing the assembly of C3/C5 convertases in both the classic and alternative pathways of the complement system.
