- a biological component can be intermixed with other components in a biological sample that can interfere with subsequent analysis.
- biological component can refer to materials of various types, including proteins, cells, cell nuclei, nucleic acids, bacteria, viruses, or the like, that can be present in a biological sample.
- a “biological sample” can refer to a fluid or a dried or lyophilized material obtained for analysis from a living or deceased organism. Isolating the biological component from other components of the biological sample can permit subsequent analysis without interference and can increase an accuracy of the subsequent analysis.
- Isolation can also be referred to as “purification”, whereby biological component may be separated from the rest of the biological sample after introduction to a sample preparation cartridge module interchangeably referred to hereafter as a sample container, a sample dispensing container, a cartridge module, and the like. It will be understood that the isolated biological component may be output in association with (e.g., bound to) particulate substrate and a reagent solution, or the like.
- isolation or purification refers to the separation of the biological component from other components of the biological sample with which it was originally introduced in the cartridge module, but it does not mean that the biological component is completely isolated when it is dispensed.
- isolation refers to the fact that the biological component is sufficiently separated or “purified” from other components of the original biological sample to facilitate further processing such as detection and/or amplification.
- isolation techniques can include repeatedly dispersing and reaggregating samples.
- the repeated dispersing and re-aggregating can result in a loss of a quantity of the biological component.
- isolating a biological component with some of these techniques can be complex, time consuming, and labor intensive and can result in less than maximum yields of the isolated biological component.
- Such Isolation techniques are done using specific devices.
- Obtaining precise biological sample preparation devices can be challenging due to many moving parts present in the devices, for example to move a carriage holding a cartridge of sample preparation cartridge modules relative to sample receiving wells.
- the cartridge may hold a plurality of the sample preparation cartridge modules or sample preparation devices or sample preparation cartridge modules which contain different respective biological samples.
- the sample dispensing containers or sample preparation devices or sample preparation cartridge modules may heat the samples to perform for example, lysis on cells in the biological samples to release biological component of interest, coming from the biological sample, may be a nucleic acid (such as DNA or RNA).
- Resulting sample fluid may be drawn through a fluid density gradient in the sample preparation cartridge modules and dispensed into sample receiving wells, which may be transferred to further analytical assay such as, for example, a Polymerase Chain Reaction (PCR).
- PCR Polymerase Chain Reaction
- initial quantities of the biological component of interest present in the biological sample may be small, precise dispensing of the component of interest from the sample preparation cartridge modules into the sample receiving wells should occur so as to not lose any content and/or to prevent cross-contamination between samples.
- a precise determination of a position of a shuttle and/or well carriage, that holds the sample receiving wells, relative to the carriage is important, and vice versa.
- the device of the present disclosure is a device that can be used to prepare a sample to be used in a process of preparing samples for a PCR (polymerase chain reaction) assay.
- PCR assays are processes that can rapidly copy millions to billions of copies of a very small DNA or RNA sample.
- PCR can be used for many different application, included sequencing genes, diagnosing viruses, identifying cancers, and others.
- sequencing genes included in the PCR process, a small sample of DNA or RNA is combined with reactants that can form copies of the DNA or RNA.
- the biological sample comprises a biological component.
- the biological component of interest coming from the biological sample, may be a nucleic acid (such as DNA or RNA).
- a particulate substrate can be configured to be associated with the biological component, to isolate the biological component from the biological sample.
- the particulate substrate comprises paramagnetic beads and/or any magnetizing particle and/or magnetizing microparticles.
- the biological component comprises nucleic acids such as DNA and/or RNA that may be extracted from the biological sample by lysing, bound to magnetic particulate substrate, and separated from the lysate and dragged towards an output by an externally generated (para)magnetic force.
- Lysate may refer to the fluid containing the material resulting from the lysis of a biological sample. Such lysis may release the biological component that is contained therein. Lysing itself may include mixing and/or heating the biological sample, chemically lysing the biological sample, and/or a combination of the foregoing.
- sample preparation devices can be challenging due to many moving parts in the devices, for example to move a carriage holding a cassette of sample preparation cartridge modules relative to sample receiving wells.
- the cassette may hold a plurality of the sample preparation cartridge module which contain different respective biological samples from humans.
- the carriage, and/or the cassette may hold the sample preparation cartridge modules in a line; similarly, the sample receiving wells may be held in a line in a well carriage, which is alternatively referred to herein as a shuttle.
- sample preparation cartridge modules may have a larger pitch in the carriage and/or the cassette, than the sample receiving wells in the shuttle, it may not be possible to align the sample preparation cartridge modules with the sample receiving wells on a line by line basis within the sample preparation device.
- the larger pitch of the sample preparation cartridge modules may be due to apparatuses interior to the sample preparation cartridge modules that are used to process a sample placed inside a sample preparation cartridge module.
- a pitch of the sample receiving wells may be set by a PCR assay device, and the like, into which a well holder, that holds the sample receiving wells, is placed, once the samples are dispensed into the sample receiving wells.
- a device that includes a carriage to hold sample preparation cartridge modules linearly arranged according to a first pitch (e.g. in a cassette) and a shuttle to: receive sample receiving wells linearly arranged according to a second pitch different from the first pitch.
- the device includes complementary mating devices to hold the carriage in a sample dispensing position at a relative given angle to the shuttle. The relative given angle may be determined from the first pitch and the second pitch such that, at a sample receiving positions of the shuttle along a linear path thereof, a sample preparation cartridge module is aligned with a respective sample receiving well.
- the shuttle may be on a planar surface that rotates in and out of the device, for example via a door.
- the planar surface When the planar surface is rotated to inside the device, the planar surface is oriented such that the carriage and the shuttle are at the relative given angle.
- the planar surface when the planar surface is rotated to outside the device (or at least partially outside the device), the planar surface is oriented such that the carriage and the shuttle are about parallel to each other.
- the planar surface may be rotated outside the device for a loading process to receive the sample receiving wells while, concurrently, the carriage is raised out of the device to a sample loading position, to receive a cassette containing the sample preparation cartridge modules that hold the samples.
- the sample preparation cartridge modules are then lowered into the device for processing while the planar surface is rotated into the device according to the relative given angle. Once dispensing occurs, the planar surface may again be rotated out of the device.
- the sample preparation cartridge modules and the sample receiving wells may be loaded into the device, or unloaded from the device, while respective linear arrangements thereof are about parallel to each other.
- a user performing the loading or unloading visually associates a first sample preparation cartridge module, holding a first sample, for example, on a left hand side of the cassette and/or the carriage, with a respective sample receiving well on a left hand side of the shuttle and/or a well holder into which the first sample is to be dispensed after processing.
- Such visual cues may assist with reducing confusion as to which sample preparation cartridge module is associated with which sample when dispensed into the wells and retrieved from the device for insertion into a PCR device.
