    Abstract: A regulatory element of a DNA for an efficient heterologous expression of proteins in Tetrahymena ssp which efficient heterologous expression is performed under control of promotors and/or terminators which are derived from in Tetrahymena ssp naturally occurring DNA comprising promotors and/or terminators and a coding region for proteins secreted ion a high level and the expression of proteins secreted on a high level is independent of the cell-cycle of Tetrahymena ssp. Furthermore a method is disclosed for the heterologous expression of proteins from Tetrahymena using gene constructs made from regulatory elements selected from the group consisting of promoters or terminators from Tetrahymena and coding nucleic acid sequences of a protein to be expressed heterologously, said regulatory elements from Tetrahymena being obtainable by: two-dimensional gel electrophoretical separation and isolation of the proteins (CMSP) selected from the group according to table 1; determination of at least one partial amino acid sequence of the proteins; establishing the nucleic acid sequence of the proteins and therefrom establishing the gene which codes for these proteins; establishing the regulatory elements of the coding region of said proteins.

    Abstract: The present invention is based on the finding that a capacitance can be measured precisely and efficiently when, in a delta-sigma modulator having an operational amplifier, a first capacitor connectable to an input of the operational amplifier, and a second capacitor in a feedback branch of the operational amplifier, a reference signal source is connectable to the first capacitor, wherein the first or second capacitor may represent a capacitance to be measured. Due to the fact that, in contrast to what is conventional, no input quantity is measured and digitalized at the input of the delta-sigma modulator, but instead a defined reference signal source is coupled at the input and a device of the delta-sigma modulator itself represents the measuring quantity, an extremely compact circuit is provided allowing capacitances to be measured quickly and reliably, the measuring result being additionally made available in a digital form.
