  • Patent number: 10190963
    Abstract: Methods and systems are disclosed for generating an entrainment factor in a flow cytometry sample. The methods comprise flowing a sample with a series of particles through the flow cytometer, detecting events and calculating an expected frequency of those events based on a distribution, such as a Poisson distribution, and measuring an observed frequency of particle events. An entrainment factor may be generated from a ratio of observed event frequency to expected event frequency. Further adjustment to the flow cytometer maybe performed based on the indicated entrainment factor such as adjusted sorting bias.

  • Patent number: 9897530
    Abstract: Apparatus and methods for detecting, characterizing, and compensating motion-related error of moving micro-entities are described. Motion-related error may occur in streams of moving micro-entities, and may represent a deviation in and expected arrival time or an uncertainty in position of a micro-entity within the stream. Motion-related error of micro-entities is observed in a flow cytometer, e.g., as pulse jitter, and is found to have a functional dependence on a parameter of the system. The pulse jitter can be compensated, according to one embodiment, by adjusting data acquisition observation windows. For the flow cytometer, a reduction of pulse jitter can improve measurement accuracy, resolution of doublets, system throughput, and enable an increase in an interrogation region for probing the micro-entities.

    Abstract: The present disclosure relates to apparatus, systems, compositions, and methods for analyzing a sample containing particles. A particle imaging system or analyzer can include a flowcell through which a urine sample containing particles is caused to flow, and a high optical resolution imaging device which captures images for image analysis. A contrast pattern for autofocusing is provided on the flowcell. The image processor assesses focus accuracy from pixel data contrast. A positioning motor moves the microscope and/or flowcell along the optical axis for autofocusing on the contrast pattern target. The processor then displaces microscope and flowcell by a known distance between the contrast pattern and the sample stream, thus focusing on the sample stream. Cell or particle images are collected from that position until autofocus is reinitiated, periodically, by input signal, or when detecting temperature changes or focus inaccuracy in the image data.

  • Patent number: 9830553
    Abstract: A code book is generated for mapping source to target code words which allows encoding source data at reduced probability of incorrect decoding, e.g. for DNA storage. The target code words are grouped (102) into subsets and comprise identifying and remaining portions. The identifying portions of target code words corresponding to a same subset are identical. A first code symbol set of source code words is selected (103) for addressing the subsets. For the subsets, neighboring subsets are determined (104). The identifying portions of the target code words of neighboring subsets differ from those of the corresponding subset by up to a predetermined amount of symbols. Source code words are assigned (105) where the corresponding first code symbols address the same subset to said subset such that an amount of target code words of said subset having their remaining portions identical to their neighboring subsets corresponds to an optimization criterion.

The stained sperm may then sorted into one or more gender enriched subpopulations of viable sperm.

  • Patent number: 9128069
    Abstract: Analysis system and computer implemented method for analyzing biological samples are disclosed. The system has at least one analyzer for performing an analysis and a decision unit being operable to determine in response to the receipt of the analysis request whether results obtained from performing the analysis on the sample indicated in the analysis request are valid. This determination is executed by retrieving the meta information assigned to the sample and by applying the at least one condition on the meta information and wherein the at least one applied condition has at least a condition on whether the sample allows a valid analysis on the sample, and wherein the decision unit returns the decision that the analysis exercised on the indicated sample will return a valid result in case the conditions of the condition set are met by the sample.

  • Patent number: 9103757
    Abstract: The present invention generally discloses an extraction system that provides a locale for fluid processing and extraction on a post-microcapture transfer film. The extraction system includes a transfer film carrier and an extraction device forming a reservoir. The extraction system selectively excludes regions of the transfer film from the reservoir to advantageously reduce contamination due to matter adhered to the transfer film by non-specific transfer.

  • Patent number: 9086409
    Abstract: The present invention is about a microfluidic chip for rapid detection of different target proteins and a method for using the same. The microfluidic chip utilizes antibody-conjugated magnetic beads to bind to the target proteins to form a magnetic complex, and then use the signal labeled-antibodies that can recognize said magnetic complex. Purifying said magnetic complex by the micro-magnetic field on biochip, and introducing said purified magnetic complex into the fluorescent detection area on the chip to detect the amount of the target protein in said purified complex immediately.

  • Patent number: 9074977
    Abstract: An analytical device such as a flow cytometer is provided in which a fluid sample flowing through a channel is focused into multiple, parallel particle streams by an acoustic wave field extending across the channel. Each stream is then presented to an individual detector to allow for simultaneous interrogation of the multiple streams and thus, high-throughput analysis of the fluid sample.

    Abstract: A novel non-enzymatic assay for lipid modulating drugs is being described for biological samples. For the first time non-enzymatic mechanism of statin drugs in modulating lipid aggregates and forming lipid particles is being shown. A simple flow cytometer based testing for detection of lipid particles, the effect of lipid modulating drug such as statin in vitro and testing for efficacy of the drug for an individual, dosage adjustment and drug discovery mechanism is being described. The lipid modulating drugs either individually or in combination can be discovered, optimized or efficacy tested using this assay. A novel statin induced lipid particle formation described can be used for diagnosis, personalized medicine and biomarker identification as well.
