We have utilized the human 4F2 heavy chain (4F2HC) gene as a model system in studies designed to elucidate the molecular events involved in regulating inducible gene expression during normal human T-cell activation. In previous studies we have shown that steady state levels of 4F2HC mRNA are induced 50-60-fold within 6 h of T-cell activation by phytohemagluttinin (PHA) and that the induction of...

Hydatid cyst fluid has been used as a source of antigen for the serodiagnosis of Echinococcus granulosus infection. Due to cross-reactions with antigens shared by other helminthes, the specific antigen from hydatid cyst fluid was purified by many workers. We used a relatively simple technique for purification of specific antigen from sheep hydatid cyst fluid. Isopycnic ultracentrifugation w...
