Tetranectin (TN) is a serum and tissue protein, a C-type lectin, which binds to Ca++. It is a homotrimer of monomers each with a mass of 20 kDa, plasma or serum concentrations of TN are found to be approximately 10 mg/l (1,2,4). In vitro, TN can bind to kringle 4 of plasminogen and enhance the activation of plaminogen to plasmin, catalyzed by tissue plasminogen activator in the presence of poly-D-lysine (3). TN is best known as a prognostic marker in ovarian cancer.
Tetranectin purified from human citrate plasma (3) and coupled to PPD. Boosted before fusion with recombinant tetranectin produced in E. coli and adsorbed onto aluminum hydroxide gel.
HYB 130-14 is specific for amino acids 17-181 of human tetranectin monomer
Epitopespecificity is shared or identical with HYB 130-10, is shared with HYB 130-11 and HYB 130-13 and is partly shared or different from HYB 130-12, as determined by inhibition ELISA (4).
HYB 130-14 reacts strongly with tetranectin. A strong reaction is seen in sandwich ELISA in combination with a polyclonal antibody against tetranectin (eg. DAKO A0371). HYB 130-14 works especially well as capture antibody in combination with HYB 130-11 in sandwich ELISA (4).
In western blotting HYB 130-14 reacts strongly with TN monomer and slightly with TN trimer. In fresh frozen tissues of ovarian cancer, HYB 130-14 shows no staining for TN and no staining of paraffin-embeded, microwave treated tissues.
