Anti-CD1A antibody produced in rabbit

CD1A (cluster of differentiation 1A) belongs to a family of antigen-presenting proteins called CD1. These are evolutionary conserved proteins which present lipids instead of peptide. Humans contain five CD1 genes namely, CD1A, CD1B, CD1C, CD1D and CD1E. CD1A is a transmembrane glycoprotein which is expressed on dendritic cells. It is the only isoform, in this family, to be expressed by Langerhans cells.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies^® protocols and other useful information.

CD1 (cluster of differentiation 1) family of proteins is responsible for the capture and presentation of self and microbial glycolipids to the specific T cells. CD1A plays an important role in the host defense mechanism against microbial infection. It also facilitates early stages of immune response through CD1A-reactive T cells. This is achieved by inducing cytokine production and dendritic cell maturation, and activating cells such as NK (natural killer) cells and macrophages. The SNP rs411089, present in an intron in the CD1A gene is associated with increased susceptibility to tuberculosis, in Vietnamese population. Hence, it can be hypothesized that CD1A plays an important role in host defense against tuberculosis. The expression of this protein is also increased in monocyte culture derived from untreated multiple sclerosis (MS) patients, as opposed to expression in monocyte culture obtained from treated MS patients.

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
