Abstract:
A graphical user interface on a computer provides for the analysis of location specific data and the presentation of analysis results for visual comparison by a user. Results of the analysis are visually presented as icons subdivided into regions and arranged in such a way that the user is able to associate each icon with a data location. A visual presentation of results in the icons and regions allows a user to visually compare the analysis results in two or more data sets according to location. The graphical user interface further provides for the definition and adjustment of an analysis through the interaction of a user with a graphical representation of the analysis. In some cases, the visual presentation of results tracks the analysis adjustments so the user can visually observe the effects that the adjustments have on the results. A method of interacting with the interface to define an analysis and represent results and a method of presenting two or more data sets using the interface are described. The interface can be used to analyze and visually compare the results of location specific data from a number of sources and is illustrated in a flow cytometry application.
Abstract:
Provided is a primary clarification depth filtration process of cell-culture feeds, including chemically treated flocculated feeds, containing target biomolecules of interest such as mAbs, mammalian cell cultures, or bacterial cell cultures, utilizing a primary clarification depth filtration device containing a media with significantly lower flushing requirements, resulting in lower levels of organic extractables released after media flushing, and increased throughput for the pre-treated feed streams, without the use of a primary clarification centrifugation step or primary clarification tangential flow microfiltration step. The primary clarification depth filtration device used in the primary clarification of fluid cell culture feeds, including chemically treated flocculated feeds containing flocculated cellular debris and/or colloidal particulates having a particle size distribution of about 0.5 μm to 200 um, contains a porous depth filter media having porous layers of varying pore ratings, and achieves the desired level, of total organic extractables (1-3 ppm) measured in the feed filtered through the media with, significantly lower flushing requirements. Kits and methods of using and making the same are also provided.
Abstract:
The present invention uses a wireless memory/communication device at least on the one or more sample storage devices, preferably on both the one or more sample storage devices and the sampling holder, optionally the port on the equipment as well. Data such as that relating to the vessel, the location of the port on the vessel, the device, its manufacture date or lot number, the date of the installation, sterilization and/or taking of a sample along with the person who installed the device and/or took the sample can he read and preferably added to the wireless device when a read/write type of device as these events occur through a scanner/reader/writer device (fixed or hand held). The sample storage device in the laboratory can also then be read and recorded to track the sample storage device's life.
Abstract:
Fluid transfer apparatus including a body having a bore formed through at least a portion of its interior. Contained within the bore is a movable plunger that moves without changing the axial dimensions of the body. A first end of the body contains a face designed to be attached to an upstream component. A second end of the body is connected to a downstream component such as a filter, pipeline, etc. A first end of the plunger, when it is in the closed position, is in alignment with the face of the body, which combined form a steamable surface and a sterile barrier against the environment to the remainder of the interior of the body, the plunger and downstream components. An outer annular collar is rotatable relative to the body and causes the plunger to move axially within the bore from an open to a closed position.
Abstract:
Method of reducing performance variability of membrane scaling devices. Scaling device performance uncertainty is reduced, thereby reducing the scaling safety factor, by specifying a narrow range or subset of the set of all qualified manufactured membranes for installation into scaling devices. In certain embodiments, the scalability factor is reduced by determining where within the performance distribution a particular membrane lies, and adjusting the scaling factor accordingly.

The invention relates generally to solid supports for chromatography. In specific embodiments the invention provides for solid supports suitable for affinity chromatography along with methods, systems and kits which use the same.
Abstract:
A system and method for interfacing non-sterile sensors to a sterile flow stream is disclosed. Typically, sensors cannot be sterilized in the same manner as other components of the flow stream. This results in complex processes to incorporate a sterilized sensor into a sterilized flow stream. By introducing a separation membrane, the desired sensor can be interfaced to the sterile flow stream. By doing so, the sensor need not be sterile, only sufficiently clean. The membrane separates the sterile environment within the flow stream from the sensor, while still permitting the sensor to function.
Abstract:
The present invention is an integral multilayered composite membrane having at least one ultrafiltration layer made by cocasting or sequentially casting a plurality of polymer solutions onto a support to form a multilayered liquid sheet and immersing the sheet into a liquid coagulation bath to effect phase separation and form a multilayered composite membrane having at least one ultrafiltration layer.

The present invention provides novel and improved stimulus responsive polymers and methods of using the same for the purification of biomolecules.
Abstract:
The present invention relates to an asymmetric chromatography media suitable for separations applications, particularly as packed bed, fluidized bed or magnetized bed chromatography media. In certain embodiments, the asymmetric chromatography media comprises asymmetric particles, preferably beads, having at least two distinct, controlled pore size distributions. Preferably one of the distinct pore size distributions is in an internal region of the particle, and the other is in an external region or coating on the particle. These distinct pore size distributions can be modified with uniform or alternatively unique functional groups or mixtures of functional groups. The present invention allows for the control over pore size distribution within an asymmetric porous particle by providing a distinct internal region, preferably in the form of a bead, and a distinct external region, preferably in the form of a coating on the bead.
