Title: System with water - water heat pump or solar energy - water heat pump
Inventor: ADAMS ROY-OLIVER
IPC: F24D11/02
Filed: 1998-02-20
Abstract: A heat distribution system provides the building, as required, with heating and cooling.

Title: Differential determination of alternatively spliced RNAs, useful e.g. for detecting mutant receptor sequence associated with myeloid leukemia, by isoform-specific polymerase chain reaction
Inventor: GANSER ARNOLD
IPC: C12Q1/6827
Filed: 1998-11-27
Abstract: Differential quantitative determination of alternatively spliced mRNAs (I) using isoform-specific, real-time reverse-transcription (RT) polymerase chain reaction (PCR).  Total cellular RNA is reverse transcribed to cDNA and this subjected to many conventional PCR cycles in presence of heat-stable polymerase, all four nucleotides, magnesium ion, a pair of target-specific sense/antisense oligonucleotide primers and either: (i) a pair of double-labeled oligonucleotide probes (P1, each carrying reporter and quencher fluorescent dyes); or (ii) a set of two pairs of singly-labeled probes (P2, each containing one such dye).  One P1, or pair of P2, recognizes an internal sequence within the target DNA, so that hybridization is essentially centered at the fusion site of a truncated DNA variant produced by splicing of a particular sequence. The other P1, or pair of P2, similarly hybridizes to a region of a longer DNA that is lacking from the truncated variant. Fluorescent emitted by excitation of the reporter dye, after hydrolysis of the probe(s) and when they are closely associated with each other, is detected; the threshold cycle determined and the original copy number of RNA corresponding to the target DNA is calculated.  An Independent claim is also included for a kit for performing the new method, containing a reverse transcriptase, thermostable polymerase and the specified PCR system.
