Polymerase chain reaction using a microfluidic chip fabricated with printed circuit board techniques
Techniques are provided for a microfluidic chip for performing a microfluidic reaction. The microfluidic chip includes a rigid layer, a first polymer layer that forms a first surface of a microfluidic chamber within the microfluidic chip, a first adhesive layer disposed between the rigid layer and the first polymer layer, and a second polymer layer that forms a second surface of the microfluidic chamber, and a first port connecting an exterior of the microfluidic chip to the microfluidic chamber through at least the rigid layer, the first polymer layer, and the first adhesive layer. A first self-sealing valve is formed in the first polymer layer and disposed within the first port, the first self-sealing valve configured to seal directly against the rigid layer through a first gap in the first adhesive layer in response to pressure from thermal expansion of a fluid within the microfluidic chamber.
Variable Temperature Analytical Instrument Assemblies, Components, and Methods for Providing Variable Temperatures
Variable temperature analytical assemblies are provided and/or methods for changing temperatures of a mass are provided. Low thermal conductance components and/or assemblies are also provided. Methods for thermally isolating a mass from a support structure are also provided.
THERMAL CONTROL DEVICE AND METHODS UTILIZING TEMPERATURE DISTRIBUTION MODELING
Thermal control devices and methods to provide improved control, speed and efficiency in temperature cycling are provided herein. Such thermal control device and methods can include one or more active elements, such a thermoelectric cooler device, that is controlled by an algorithm that regulates a temperature distribution of an adjacent reaction-vessel according to a temperature distribution command trajectory and estimated reaction-vessel temperature distribution. Some embodiments include two active elements that are bilaterally applied to opposing sides of the reaction-vessel. In some embodiments, the estimated reaction-vessel temperature is determined based on a state of power electronics of the element and a temperature output of one or more sensors of a portion of the element and/or an ambient environment of the reaction-vessel. Methods of calibration of such systems utilizing a thermal calibrator as a proxy for the reaction-vessel are also provided herein.
INTEGRATED AIR FILTERING AND CONDITIONING OF DROPLET CHAMBER IN A COMPACT CELL SORTER
A compact sorting flow cytometer system is disclosed. The system includes a fluidics system having a flow cell and a deflection chamber in communication with the flow cell to receive drops in a stream of a sample biological fluid with one or more biological cells or particles and selectively deflect the drops in the stream of the sample biological fluid with the one or more biological cells or particles; and a droplet deposition unit (DDU) system in communication with the deflection chamber to receive the selectively deflected drops in the stream of the sample biological fluid with the one or more biological cells or particles into one or more containers. The DDU system includes a case or a housing with an open face surround by edges of the case, the case forming a portion of a containment chamber, the case having a top side opening aligned with the deflection chamber to receive the selectively deflected drops in the stream of the sample biological fluid into one or more containers in the containment chamber, a seal mounted around edges of the case, one or more hinges coupled to a bottom portion of the case, and a door coupled to the one or more hinges to pivot the door about the one or more hinges, the door when closed to press against the seal and close off the containment chamber from an external environment.
A method for evacuation of air in a containment chamber of a flow cytometer is disclosed. The method includes turning off a return fan in a first tunnel between an air conditioning chamber and a containment chamber; turning on an evacuation fan in a second tunnel between the air conditioning chamber and the containment chamber, the evacuation fan pulling air out of the containment chamber into the air conditioning chamber, opening a valve in an evacuation vent, the evacuation fan pushing air out of the air conditioning chamber through the evacuation vent into the environment; and continuously running the evacuation fan for a predetermined period of time to evacuate air out of the containment chamber.
INTEGRATED REAGENT CARTRIDGE
An integrated reagent cartridge can be configured to hold and deliver reagents during sequencing. The integrated reagent cartridge can include a large-volume reagent region, a small-volume reagent region, a top cover, a bottom shell assembly, and a manifold assembly.
BAG HOLDER FOR PLATE FREEZING
Bag holders for plate freezing of bags containing fluids such as reactor bags, in particular bags containing biological or chemical reagents can include genderless bag trays. Each bag tray can include a basin defined in part by a first side wall and a second side wall. The basin can be configured to hold the bag. The first side wall can include a first retaining feature and the second side wall can include a second retaining feature having a shape complementary to the first retaining feature. The complementary nature of first and second retaining features allows identical bag trays to be joined by each of their respective first and second retaining features to one another. Methods include forming first and second bag trays, placing a bag within the first bag tray, joining the second bag tray to the first bag tray, and freezing the bag by a plate freezing process.
HTP GENOMIC ENGINEERING PLATFORM
The present disclosure provides a HTP microbial genomic engineering platform that is computationally driven and integrates molecular biology, automation, and advanced machine learning protocols. This integrative platform utilizes a suite of HTP molecular tool sets to create HTP genetic design libraries, which are derived from, inter alga, scientific insight and iterative pattern recognition. The HTP genomic engineering platform described herein is microbial strain host agnostic and therefore can be implemented across taxa. Furthermore, the disclosed platform can be implemented to modulate or improve any microbial host parameter of interest.
