一般說明
The gene DSCR4 (Down syndrome critical region protein-4) is mapped to human chromosome 21q22.2. DSCR4 is restricted to human placenta.
免疫原
Down syndrome critical region protein 4 recombinant protein epitope signature tag (PrEST)
應用
Anti-DSCR4 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.
生化/生理作用
Down syndrome critical region protein-4 (DSCR4) promoter is shown to be a fetal epigenetic marker for noninvasive prenatal detection of chromosomal aberration trisomy 21. DSCR4 promoter is hypomethylated in placental and densely methylated in maternal blood cells. However, unmethylated DSCR4 can be identified in the first-trimester maternal plasma.
特點和優勢
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:
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.

Trisomy 21 is the most common chromosomal aberration in live births. Some efforts have been made to develop noninvasive prenatal detection of trisomy 21 by using fetal DNA in maternal plasma. Due to the maternal DNA background, a distinguishable marker
