General description

Bloom syndrome protein (BLM) is a DNA helicase belonging to the RecQ family, having 1417 amino acids. The gene encoding it is present on chromosome 15. BLM contains an amino-terminal and a carboxy-terminal region which is composed predominantly of charged polar amino acid residues.

Immunogen

Bloom syndrome protein recombinant protein epitope signature tag (PrEST)

Application

Anti-BLM 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. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige. Anti-BLM antibody produced in rabbit is also suitable for immunoprecipitation.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Biochem/physiol Actions

Bloom syndrome protein (BLM) plays an important role in the maintenance of genomic stability in somatic cells. It functions in the complex processes of DNA replication where it interacts with topoisomerase II. BLM is also a part of a DNA surveillance mechanism (BRCA1-associated) operating during S phase and is found in the nucleolus of S Phase cells, interacting with a protein WRN. It binds to p53, topoisomerase IIIa, RAD5 (a DNA repair protein) and is thus associated with several aspects of DNA metabolism like DNA recombination, replication, and repair.

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.
