Abstract

A system and method of mixing and injecting discrete sample mixtures into a flow cytometer or other sample analysis apparatus may generally comprise a sample injection guide coupling a liquid handling apparatus with a sample analysis apparatus and facilitating injection of discrete sample mixtures into a fluidic system of the apparatus.

Claims (43)

1. A sample analysis system comprising:

a liquid handling apparatus operative to prepare a discrete sample mixture, wherein the liquid handling apparatus comprises a coupling component that is operative to accommodate disposable pipette tips, and wherein the coupling component enables automatic ejection of the disposable pipette tips;

wherein the coupling component comprises an exterior portion operative to engage, under pressure, a cooperating open end of a disposable pipette tip, and an interior portion that includes a conical recess at a distal end of the coupling component;

a sample analysis apparatus; and

an injection guide coupled to said analysis apparatus; said injection guide operative to receive said discrete sample mixture from said liquid handling apparatus and to provide said discrete sample mixture to a fluidic system of said analysis apparatus.

2. The system of claim 1 wherein said injection guide comprises:

a guide well operative to engage a pipette tip manipulated by said liquid handling apparatus; and

a port in fluid communication with said guide well and operative to receive said discrete sample mixture from said pipette tip and to communicate said discrete sample mixture to said fluidic system.

3. The system of claim 2 wherein said guide well and said port are in continuous fluid communication with said fluidic system.

4. The system of claim 1 wherein said liquid handling apparatus comprises a single arm liquid handler.

5. The system of claim 1 wherein said liquid handling apparatus comprises a multiple arm liquid handler.

6. The system of claim 1 wherein said multiple arm liquid handler employs two pipetting arms.

7. The system of claim 1 further comprising a cell suspension system operative to maintain sample cell material at a substantially constant density throughout a volume of suspension medium.

8. The system of claim 7 wherein said cell suspension system comprises:

a suspension vessel containing said sample cell material and said suspension medium; and

a rocking apparatus operative to agitate said sample cell material and said suspension volume in said suspension vessel.

9. The system of claim 8 wherein said suspension vessel comprises a sealed tube having an aperture; said aperture allowing a component of said liquid handling apparatus to withdraw a volume of said sample cell material and said suspension volume from said tube.

10. A sample analysis system comprising:

a liquid handling apparatus operative to prepare a discrete sample mixture, wherein the liquid handling apparatus comprises a coupling component that is operative to accommodate disposable pipette tips, and wherein the coupling component enables automatic ejection of one or more disposable pipette tips;

wherein the coupling component comprises an exterior portion operative to engage, under pressure, a cooperating open end of a disposable pipette tip, and an interior portion that includes a conical recess at a distal end of the coupling component;

a sample analysis apparatus, wherein said sample analysis apparatus comprises a flow cytometer; and

an injection guide coupled to said analysis apparatus; said injection guide operative to receive said discrete sample mixture from said liquid handling apparatus and to provide said discrete sample mixture to a fluidic system of said analysis apparatus.

11. A sample analysis system comprising:

a liquid handling apparatus operative to prepare a discrete sample mixture, wherein the liquid handling apparatus comprises a coupling component; said coupling component being operative to accommodate disposable pipette tips wherein the coupling component comprises an exterior portion operative to engage, under pressure, a cooperating open end of a disposable pipette tip, and an interior portion that includes a conical recess at a distal end of the coupling component;

a mechanical ejector within the coupling component for automatically ejecting the disposable pipette tips;

a sample analysis apparatus;

an injection guide coupled to said analysis apparatus; said injection guide operative to receive said discrete sample mixture from said liquid handling apparatus and to provide said discrete sample mixture to a fluidic system of said analysis apparatus; and

a processing component operative to acquire a first data set associated with said discrete sample mixture from said liquid handling apparatus, to acquire a second data set associated with said discrete sample mixture from said sample analysis apparatus, to compare said first data set with said second data set to correlate data records with said discrete sample mixture, and to perform an analysis on said data records associated with said discrete sample mixture.

12. The system of claim 11 wherein said injection guide comprises:

a guide well operative to engage a pipette tip manipulated by said liquid handling apparatus; and

a port in fluid communication with said guide well and operative to receive said discrete sample mixture from said pipette tip and to communicate said discrete sample mixture to said fluidic system.

13. The system of claim 12 wherein said guide well and said port are in continuous fluid communication with said fluidic system.

14. The system of claim 11 wherein said processing component is further operative to control said liquid handling apparatus.

15. The system of claim 14 wherein said liquid handling apparatus comprises a single arm liquid handler.

16. The system of claim 14 wherein said liquid handling apparatus comprises a multiple arm liquid handler.

17. The system of claim 16 wherein said multiple arm liquid handler employs two pipetting arms cooperating under control of said processing component to prepare said discrete sample mixture.

18. The system of claim 11 further comprising a cell suspension system operative to maintain sample cell material at a substantially constant density throughout a volume of suspension medium.

19. The system of claim 18 wherein said processing component is further operative to control operation of said cell suspension system.

20. The system of claim 1 , further comprising one or more disposable pipette tips.

21. The system of claim 20 , wherein the coupling component and the disposable pipette tip, when sealingly engaged to form a juncture, prevent leakage at the juncture.

22. The system of claim 11 , further comprising one or more disposable pipette tips.

23. The system of claim 22 , wherein the coupling component and the disposable pipette tip, when sealingly engaged to form a juncture, prevent leakage at the juncture.

24. The system of claim 1 , further comprising a mechanical ejector within the coupling component for automatically ejecting the disposable pipette tips.
