Abstract: Separator paper comprising paper impregnated with soluble silicate. The soluble silicate may be applied to the separator paper by immersing the paper into an aqueous solution of the soluble silicate or by spraying with an aqueous solution of the soluble silicate. In a preferred embodiment, the soluble silicate is sodium silicate. An electrolytic capacitor comprising an electrolytic solution, at least one anode foil, at least one cathode foil, and separator paper between the at least one anode foil and at least one cathode foil, wherein the separator paper comprises paper impregnated with a soluble silicate.

Abstract: The present invention relates to isolation of cytotoxic T lymphocyte (CTL) clones. In particular, the present invention relates to isolated CTL clones that are specific for MAGE-1 and MAGE-4, respectively. The CTL clones of the present invention have been isolated by successive steps of stimulation and testing of lymphocytes with antigen presenting cells which present antigens derived from different expression systems, e.g., from recombinant Yersinia, recombinant Salmonella, or recombinant viruses. The present invention further relates to the MAGE-1 and MAGE-4 antigenic peptides as well as the peptide/HLA complexes which are recognized by the isolated CTL clones.
