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.
HYB 130-11 is specific for amino acids 17-181 of human tetranectin monomer
Epitope specificity is shared HYB 130-13, as determined by inhibition ELISA (4).
HYB 130-11 reacts poorly with tetranectin in sandwich ELISA in combination with a polyclonal antibody against tetranectin (eg. DAKO A0371). In western blotting HYB 130-11 reacts strongly with TN monomer. Especially good as detecting antibody in combination with HYB 130-14 in sandwich ELISA.
Strong recognition of tetranectin in immunohistochemistry on both fresh frozen and paraffin-embedded tissues (4).
