摘要:
The present invention relates to a multiwell filtration plate system formed of a multiwell filter plate, an underdrain, preferably having spouts as the outlet from the underdrain and a collection device such as a collection plate and the use of a mechanical device such as a fixture in the form of a post, a ramp, a rib, a spout protector ring and the like formed in the collection plate wells or on the outside of the underdrain or both for contacting a forming pendant drop formed on the spout of the underdrain and transferring it to the collection plate well.
摘要:
The present invention provides a device in a multiwell plate that allows for one to obtain substantially all of the liquid that has flowed through the filter thereby reducing hold up volume. This is accomplished by forming at least one hydrophobic area in the hydrophilic filter in each well. After the filtration has occurred, air is allowed to enter the underdrain of the plate through the hydrophobic area(s) which causes any residual fluid held by surface tension to be released and to flow out of the underdrain to the outside environment.

The present invention is to a filter plate and a collection system having an upper filter plate and a lower collection plate. Each has two or more wells in register with each other. The filter plate has an underdrain containing a spout. The spout is offcenter of the centerpoint of the wells between which it resides. The spout is close to at least one wall of the well of the collection device but set off from that wall by a distance sufficient to ensure easy assembly and disassembly of the devices without contact or damage of the spout with the well of the collection device. In this manner, any drop that begins to form contacts the adjacent well wall and travels down it into the collection device.
摘要:
Underdrain design for a multiwell device that when fixed to the device (either as an integral or removable component thereof), allows for adequate venting during filtration, minimizes or prevents air lock, and has improved structural integrity. Also disclosed is a laboratory device designed particularly for a multiplate format that includes a plate or tray having a plurality of wells, and an underdrain in fluid communication with each of the plurality of wells. The underdrain can be a separate, removable piece, or can be an integral unitary structure with the plate or tray forming a one-piece design. The design is preferably in compliance with SBS format.
摘要:
Multiwell filter comprising a filter plate having a plurality of wells, each including a support. Each well has a corresponding adjacent access port providing access to the corresponding feeding/receiver plate well, e.g. via a pipette. When the filter plate is positioned over a feeding/receiver plate having a plurality of wells, each well of the feeding/receiving plate aligns with and communicates with a corresponding filter plate well. Each access port provides access to a respective well in the feeding/receiver plate, and the wells in the filter plate are not centrally located with respect to the feeding/receiver plate wells, but are shifted in the x and y directions relative to the receiver wells in an amount effective for reducing or eliminating capillary holdup in the gap between the filter wells and the feeding/receiver wells. The wells in the feeding/receiver plate preferably are formed in a U-shaped bottom below each access port.
摘要:
A plate liner detachably engageable onto a microarray plate (or underdrain plate component thereof), suited for preventing or confining pendant drop formation. It is provided either as a stand-alone item, or—preferably—in kit form, within a sanitary package, together with other pre-matched microarray filtration components.
摘要:
The invention provides a method of treating neoplastic disease in a subject, said method comprising the simultaneous, sequential or separate, administration to said subject of an effective amount of (i) an inhibitor of a first EGF, e.g. HB-EGF and (ii) an inhibitor of a second EGF, e.g. AREG. Also described are novel synergistic combinations of EGF inhibitors with topoisomerase inhibitors which attenuate tumour cell growth. Further described are novel anti AREG antibodies.
摘要:
A device for training medical personnel to measure a simulated patient's temperature is provided. The device includes at least one sensor configured to measure an attribute of the device's motion. A display and a wireless communications device are provided. A controller is electrically coupled to the at least one sensor, the display and the wireless communications device, the controller having a processor that is responsive to executable computer instructions to display a value on the display in response to the at least one sensor measuring the attribute.
摘要:
A lubricated part composition containing (a) a part with at least a partial hard surface coating of average thickness less than about 25 micrometres, said coating containing at least one moiety selected from the group consisting of silicides, nitrides, carbides, borides, oxides, sulphides and mixtures thereof; (b) a detergent selected from at least one of the group consisting of a phenate salt, a sulphonate salt, a salixarate salt and mixtures thereof; and (c) an oil of lubricating viscosity. The invention further relates to the use of the composition to decrease engine wear, decrease sludge formation, filter plugging, decrease sulphur emissions and decrease phosphorus emissions.
摘要:
Described is a novel purification tag, SNUT, based on the gene product of a sortase gene, in particular the srtA gene of Staphylococcus aureus and uses thereof. Also provided are expression constructs comprising DNA enoding the tag for the production of recombinant polypeptides. The tag can be used in methods of purifying soluble domains of a number of proteins previously not able to be isolated efficiently and methods of inducing and/or enhancing an immune response to an antigen of interest.
