Recombinant monoclonal antibody to Triplex DNA. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the hybridoma Jel 466.
Alternative Name(s) of Target: triple helix DNA; Jel-466; Jel466
Immunogen: Jel 466 was prepared by immunizing mice with poly[d(Tm5C)].poly[d(GA)].
Specificity: Jel 466 binds to triple-stranded DNA. The preferred interacting partner is the triplex form of poly[d(TC)]. poly[d(GA)] and there is also good binding to poly[d(TTC)].poly[d(GAA)]. Theantibody binds weakly to the triplex derived from poly[d(G)].poly[d(C)] and no binding is observed with poly[d(T)].poly[d(A)1.poly[d(T)]. Jel 466 does not bind to poly[d(TC)].poly[d(Gm6A)], single-stranded DNAs, calf thymus DNA, or to poly[d(TG)].poly[d(CA)] which are unable to form a triplex structure. Triplex DNA has been known to form in vitro from synthetic pyrimidine-pruine tracts and it is also thought to potentially have a biological function in cells. These functions include the control of gene expression due to the presence of pyrimidine-purine tracts in the 5' control region and chromosomal organization whereby DNA loops can be stabilised by triplexes (some MARs [matrix attched regions] contain triplez-forming sequences).
Application Notes: Jel 466 can be used to detect triplex DNA in cells by IF.
