Abstract

Embodiments of the present invention encompass systems and methods for determining detection limits for various antibody-dye conjugates for flow cytometry. Exemplary techniques involve a linear superpositioning approach of spillover-induced enlargements of normally distributed measurement errors.

Claims (51)

1. A method for determining a first ranking for an optimized probe panel for differentiating populations of particles in a sample using an antibody database module, the method comprising:

receiving, via a user interface, user input corresponding to one or more parameters of a probe panel, the one or more parameters including a set of antibodies corresponding to an antigenic expression pattern;

determining, via a processor, the first ranking for the optimized probe panel based on the user input, the determining comprising:

running a simulation of probe panels that satisfy the user input including determining a detection limit for each of one or more detection channels based on the antigenic expression pattern;

generating the first ranking for the optimized probe panel based on the detection limit and experimental data; and

displaying, via the user interface, the first ranking for the optimized probe panel.

2. The method of claim 1 , further comprising:

retrieving, via the antibody database module, part information associated with the first ranking for the optimized probe panel; and

displaying, via the user interface, the part information for the first ranking for the optimized probe panel.

3. The method of claim 1 , wherein the one or more parameters of the probe panel includes one or more antibody parameters.

4. The method of claim 3 , further comprising:

retrieving, via the antibody database module, antibody parameter options; and

displaying, via the user interface, the antibody parameter options for selection of the user input.

5. The method of claim 1 , wherein determining the first ranking for an optimized probe panel includes determining based on a fluorochrome property and a signal intensity.

6. The method of claim 5 , wherein the signal intensity is an expected signal intensity based on an expression density of a targeted antigen.

7. The method of claim 1 , wherein the experimental data includes a classification of each antibody in the set of antibodies corresponding to an antigenic expression vector as dim, modulated, or bright; and

wherein the classification of an antibody as dim, modulated, or bright is a parameter used in generating the first ranking for the optimized probe panel.

8. The method of claim 1 , wherein receiving the user input includes:

receiving, via the user interface, selection of one or more antibodies; and

receiving, via the user interface, assignment of the one or more antibodies to one or more dyes.

9. The method of claim 1 , wherein receiving the user input includes:

receiving, via the user interface, selection of one or more antibodies;

retrieving, via the antibody database module, an optimal dye assignment for each of the one or more antibodies; and

displaying, via the user interface, the optimal dye assignment.

10. The method of claim 1 , wherein receiving the user input includes:

receiving, via the user interface, selection of one or more antigens; and

receiving, via the user interface, assignment of the one or more antigens to one or more phenotypes.

11. The method of claim 1 , wherein receiving the user input includes:

receiving, via the user interface, selection of one or more antigens;

retrieving, via the antibody database module, a phenotype assignment for each of the one or more antigens; and

displaying, via the user interface, the phenotype assignment.

12. The method of claim 1 , further comprising: determining at least one additional ranking for at least one additional optimized probe panel for differentiating populations of particles in the sample using the antibody database module, the method comprising the steps of claim 1 ; and

displaying, via the user interface, the first ranking for an optimized probe panel and any additional rankings for additional optimized probe panels.

13. A system for determining a first ranking for an optimized probe panel for differentiating populations of particles in a sample, the system comprising:

a user interface configured to receive user input corresponding to one or more parameters of a probe panel, the one or more parameters including a set of antibodies corresponding to an antigenic expression pattern;

a processor in electronic communication with the user interface, the processor configured to determine the first ranking for the optimized probe panel based on the user input by:

running a simulation of probe panels that satisfy the user input including determining a detection limit for each of one or more detection channels based on the antigenic expression pattern;

generating the first ranking for the optimized probe panel based on the detection limit and experimental data; and

a memory in electronic communication with the processor, the memory storing an antibody database module including antibody information and part information corresponding to probe panels,

wherein the processor is configured to retrieve part information associated with the first ranking for the optimized probe panel via the antibody database module and display the part information via the user interface.

14. The system of claim 13 , wherein the antibody database module includes data concerning fluorochrome properties and signal intensities related to expression density of a targeted antigen.

15. The system of claim 13 , wherein the antibody database module includes data concerning parent-descendant patterns.

16. The system of claim 13 , wherein the part information includes part numbers.

17. The system of claim 13 , wherein the antibody database module includes estimated values.

18. The system of claim 13 , wherein the experimental data includes a classification of each antibody in the set of antibodies corresponding to an antigenic expression vector as dim, modulated, or bright; and

wherein the classification of an antibody as dim, modulated, or bright is a parameter used in generating the first ranking for the optimized probe panel.

19. The system of claim 13 , wherein the processor is configured to determine at least one additional ranking for at least one additional optimized probe panel; and

wherein the system displays via the user interface the first ranking for an optimized probe panel and any additional rankings for additional optimized probe panels.

20. A user interface for determining a first ranking for an optimized probe panel for differentiating populations of particles in a sample, the user interface comprising:

a user input device configured to receive user input corresponding to one or more parameters of a probe panel, the one or more parameters including a set of antibodies corresponding to an antigenic expression pattern; and

a user output device configured to display part information retrieved from an antibody database module, wherein the part information is associated with the first ranking of an optimized probe panel selected by a processor based on the user input and a simulation of probe panels that satisfy the user input including determining a detection limit for each of one or more detection channels based on the antigenic expression pattern.
