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

SAFB (scaffold attachment factor B) is a multifunctional, nuclear matrix protein belonging to the SAFB family. It is involved in various cellular processes including cell growth, apoptosis, and stress response. It plays a vital role in chromatin organization, transcriptional control, and RNA processing. Its C-terminal domain possesses potential tumor suppressive characteristics. It suppresses transcriptional signals through the direct promoter-binding or indirect transcription factor interactions. It also acts as an estrogen receptor corepressor. It inhibits the expression of estrogen receptor in combination with SAFB2 through the C-terminal binding.

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.

SAFB1 (scaffold attachment factor B1) and a second family member SAFB2, are multifunctional proteins implicated in a variety of cellular processes including cell growth, apoptosis and stress response. Their potential function as tumour suppressors has been proposed based on well-described

We have characterized previously the nuclear matrix protein/scaffold attachment factor (SAFB) as an estrogen receptor corepressor and as a potential tumor suppressor gene in breast cancer. A search of the human genome for other potential SAFB family members revealed that
