Aspects of the present disclosure include reconfigurable integrated circuits for characterizing particles of a sample in a flow stream. Reconfigurable integrated circuits according to certain embodiments are programmed to calculate parameters of a particle in a flow stream from detected light; compare the calculated parameters of the particle with parameters of one or more particle classifications; classify the particle based on the comparison between the parameters of the particle classifications and the calculated parameters of the particle; and adjust one or more parameters of the particle classifications based on the calculated parameters of the particle. Methods for characterizing particles in a flow stream with the subject integrated circuits are also described. Systems and integrated circuit devices programmed for practicing the subject methods, such as on a flow cytometer, are also provided.

Reconfigurable integrated circuits for adjusting cell sorting classification

In flow cytometry, particles () can be distinguished between populations () by combining n-dimensional parameter data, which may be derived from signal data from a particle, to mathematically achieve numerical results representative of an alteration (). An alteration may include a rotational alteration, a scaled alteration, or perhaps even a translational alteration. Alterations may enhance separation of data points which may provide real-time classification () of signal data corresponding to individual particles into one of at least two populations.

Enhancing flow cytometry discrimination with geometric transformation

Flow cytometric droplet dispensing systems and methods for using the same to flow cytometrically dispense droplets into partitions are provided. Aspects of embodiments of the systems include sorting flow cytometers configured to sort both particle-occupied and particle-unoccupied droplets into a partition. Also provided are methods of using the systems. Systems and methods of the invention find use in a variety of applications.

Flow cytometric droplet dispensing systems and methods for using the same

Some embodiments of the methods provided herein relate to sample analysis and particle characterization methods. Some such embodiments include receiving, from a particle analyzer, measurements for a first portion of particles associated with an experiment. Some embodiments also include generating a tree representing groups of related particles based at least in part on the measurements, wherein the tree includes at least three groups. Some embodiments also include generating a measure of relatedness between a first group and a second group of the tree based at least in part on the measurements. Some embodiments also include and configuring the particle analyzer to classify a subsequent particle associated with the experiment with the first group real-time, wherein the subsequent particle is not included in the first portion of particles. Some embodiments also include sorting the subsequent particle.

Characterization and sorting for particle analyzers

Disclosed are computer-implemented methods of sorting particles from a particle stream in a flow cytometer. The methods include: calculating sort decision making parameters using the raw event data values from a flow cytometer and a sort logic; performing sort logic computations using the sort logic definition and the sort decision making parameters to generate sort decisions; converting the sort decisions into sort commands; and sending the one or more sort commands to the flow cytometer. Sort logic computations may include algorithmically using conditional branching logic, and may include sort logic equations having mathematical functions characterizing one or more regions of interest in multidimensional data space. Such mathematical functions may be determined based on one or more parameters provided by a user. Also disclosed are corresponding systems having a flow cytometer and a computer.

Flow cytometer sorter

A flow cytometry apparatus and methods to process information incident to particles or cells entrained in a sheath fluid stream allowing assessment, differentiation, assignment, and separation of such particles or cells even at high rates of speed. A first signal processor individually or in combination with at least one additional signal processor for applying compensation transformation on data from a signal. Compensation transformation can involve complex operations on data from at least one signal to compensate for one or numerous operating parameters. Compensated parameters can be returned to the first signal processor for provide information upon which to define and differentiate particles from one another.
