Anti-LAG3 antibody produced in rabbit

General description

The protein lymphocyte-activation gene 3 encoded by the gene LAG-3 is expressed by various lymphoid cell types and plasmacytoid dendritic cells.

Immunogen

Lymphocyte activation gene 3 protein precursor recombinant protein epitope signature tag (PrEST)

Application

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.

Biochem/physiol Actions

The gene LAG3 (lymphocyte-activation gene 3) encodes a member of the Ig superfamily. The encoded protein is a CD4-related molecule that interacts with and binds to MHC class II. It functions in the regulation of plasmacytoid dendritic cell homeostasis. It is expressed by activated natural CD4⁺CD25⁺ Tregs (regulatory T cells) and enhances the suppressor activity of CD4⁺ T cells towards effector T cells. It is involved in the regulation of Treg homeostasis and function, apart from mediating induced Treg development. This immune inhibitory molecule also functions in mitigating dendritic cell differentiation and function. It functions in synergy with programmed cell death 1 (PD-1) to facilitate tumoral immune escape.

Features and Benefits

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.

Linkage
