    • The present invention provides methods for detecting and identifying sequence variations in a nucleic acid sequence of interest using a detector primer. It has been found that the reduced efficiency of primer extension by DNA polymerases when the 3′ end of a primer does not hybridize perfectly with the target can be adapted for use as a means for distinguishing or identifying the nucleotide in the target which is at the site where the diagnostic mismatch between the detector primer and the target occurs. The detector primer hybridizes to the sequence of interest and is extended with polymerase. The efficiency of detector primer extension is detected as an indication of the presence and/or identity of the sequence variation in the target. The inventive methods make use of nucleotide mismatches at or near the 3′ end of the detector primer to discriminate between the nucleotide sequence of interest and a second nucleotide sequence which may occur at that same site in the target. The methods are particularly well suited for detecting and identifying single nucleotide differences between a target sequence of interest (e.g., a mutant allele of a gene) and a second nucleic acid sequence (e.g., a wild type allele for the same gene).
    • 本发明提供使用检测器引物检测和鉴定感兴趣的核酸序列中的序列变异的方法。 已经发现,当引物的3'端没有与靶完全杂交时,通过DNA聚合酶的引物延伸的效率降低可以适用于区分或鉴定靶中的核苷酸的手段 发现检测器引物与靶标之间的诊断不匹配的位置。 检测引物与感兴趣的序列杂交,并用聚合酶扩增。 检测器引物延伸的效率被检测为目标中序列变异的存在和/或身份的指示。 本发明的方法利用在检测器引物的3'末端附近或其附近的核苷酸错配来区分目的核苷酸序列和可能发生在靶的相同位点的第二核苷酸序列。 所述方法特别适用于检测和鉴定靶标目标序列(例如,基因的突变等位基因)和第二核酸序列(例如,相同基因的野生型等位基因)之间的单核苷酸差异。

    • A method of treating a solid material containing a substance of economic importance so as to recover or extract the substance from the material involving the following: forming a conducting mixture of the solid with a liquid so that at least some of the substance of economic importance is dissolved in the liquid, applying an electrical potential difference between at least two electrodes in contact with the mixture at spaced apart locations so as to impart opposite charges to the respective electrodes thereby attracting the liquid containing the dissolved substance to one of the electrodes, removing the liquid from an area surrounding or from a vicinity of the one electrode, and treating the liquid containing the substance of economic importance so as to recover or extract the substance. The liquid used is at least partially conducting. The present method is particularly useful for extracting or recovering gold from gold-containing or gold bearing ores.

    • A bath shaker (10) is provided for agitating liquid baths. The bath shaker (10) incorporates a "flexible parallelogram" mode of movement wherein a bath shelf (20) is attached to and supported by two, parallel opposing flexible arms (112). Present on each flexible arm (112) is a first attachment portion (124) sandwichedly held by an upright extension (120) and a first hold plate (110), the arrangement causing the first attachment portion (124) to serve as a flexible hinge. A drive mechanism (16) produces a reciprocating action of the bath shelf (20) through the use of an eccentric (80) and a pivoting lever (46) attached to both the eccentric (80) and the bath shelf (20). The flexible parallelogram arrangement defines the reciprocating motion to be substantially rectilinear and makes for an entirely noiseless mode of travel, while producing an extremely smooth transition between reciprocations. Two bath containers (24) are supported by the bath shelf (20) and are provided with a highly accurate temperature control system (26).
