Tyrosine-protein kinase BTK recombinant protein epitope signature tag (PrEST)


Anti-BTK antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project ( Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting.

Biochem/physiol Actions

BTK (Bruton agammaglobulinemia tyrosine kinase) gene encodes a non-receptor tyrosine kinase that has a crucial role in B lymphocyte development, differentiation and signaling. It is essential for lipopolysaccharide (LPS)-induced as well as Toll-like receptors (TLR2 and TLR4)-induced tumor necrosis factor (TNF) production. Bright, a member of the ARID family of transcription factors, promotes immunoglobulin heavy-chain transcription via association with the transcription factor TFII-I and Btk. Btk interacts with and activates signaling by Toll-like receptors (TLR8 and TLR9) that are involved in the detection of pathogens and activation of host defense. Defects in this gene cause X-linked agammaglobulinaemia (XLA), a humoral immunodeficiency disease.

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.


Corresponding Antigen APREST78234.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
