摘要:
A fishing rod provides a lighting system that includes a timer circuit and a motion responsive switch. In response to motion, the timer circuit activates lights to illuminate the fishing rod for a pre-determined interval. The circuit extinguishes the lights at the end of the interval. Preferably, the fishing rod is fabricated of a translucent material and the lights are LEDs housed within the core of the fishing rod.
摘要:
Methods of and apparatus for washing an array of sites in high-density microplates or similar assay plates wherein the microplates or assay plates are washed in an inverted or nearly inverted position, rather than in an upright position. Preferably, the wash liquid is dispensed upwardly in the form of a sheet from a nozzle mounted on a spray bar as the spray bar moves relative to the microplate or assay plate. After washing, the microplate or assay plate is dried with a stream of gas such as air, also preferably blown upwardly in the form of a sheet.
摘要:
A method to detect one or more nucleic acids of interest, which includes subjecting a sample that contains said nucleic acid(s) to nuclease protection with one or more protection fragments, and detecting the hybridized duplex molecules, or the single strand protected nucleic acid(s), or the protection fragment(s) with mass spectrometry.
摘要:
Hybridoma cell lines producing monoclonal antibodies specific to the human epidermal growth factor receptor are disclosed. The antibodies are capable of inhibiting the growth of human tumor cells expressing human epidermal growth factor receptors. Therapeutic uses of these monoclonal antibodies by themselves and in combination with anti-neoplastic agents are also disclosed.
摘要:
The present invention relates to compositions, apparatus and methods useful for concurrently performing multiple, high throughput, biological or chemical assays, using repeated arrays of probes. A combination of the invention comprises a surface, which comprises a plurality of test regions, at least two of which, and in a preferred embodiment, at least twenty of which, are substantially identical, wherein each of the test regions comprises an array of generic anchor molecules. The anchors are associated with bifunctional linker molecules, each containing a portion which is specific for at least one of the anchors and a portion which is a probe specific for a target of interest. The resulting array of probes is used to analyze the presence or test the activity of one or more target molecules which specifically interact with the probes. In a preferred embodiment, a sample to be tested is subjected to a nuclease protection procedure before it is contacted with a combination of the invention.
