The present invention includes a high throughput screen for an active agent for the treatment of comprising: plating cells at least one pathophysiologically relevant mislocated mutant form of a peroxisomal enzyme; adding a control and compound to each plate from a library of compounds; fixing the cells; contacting the cells with an agent that detects the mislocated mutant form of a peroxisomal enzyme; and imaging the cells in the wells.

A device including a microfluidic channel structure formed on a substrate and including a first channel and a fluid actuator within the microfluidic channel structure. A sense region within the first channel is to receive a fluid flow of target biologic particles for counting in a single file pattern, with the sense region having a volume on a same order of magnitude as a volume of a single one of the target biologic particles.

A data receiver thread is continuously executed to receive in which signals indicating a fluid parameter. A predetermined time quantity of the signals is repeatedly buffered. Upon completion of the buffering of each predetermined time quantity of the signals, a data processing thread is initiated that executes on the just completed buffered predetermined time quantity of signals. Upon completion of each data processing thread, data from the just completed data processing thread is passed to a data plotting thread. Results of the data plotting thread are displayed on a portable electronic device while the data receiver thread is being executed.

The present invention relates to Chimeric Antigen Receptors (CAR) that are recombinant chimeric proteins able to redirect immune cell specificity and reactivity toward CLL1 positive cells. The engineered immune cells endowed with such CARs are particularly suited for immunotherapy for treating cancer, in particular leukemia.

An immersion cytometry system (200, 250) having a primary focusing optic immersed in a fluid stream (209) containing suspended particles (212). The system includes a light source (202) configured to illuminate a sensing region in the fluid stream that includes a focus of the primary optic. Light scattered and/or fluoresced from suspended particles passing through the sensing region is focused by an external tube lens on an external detector. The primary optic in one embodiment is a ball lens. In some embodiments, one or more filter/beam splitters on the optical axis reflect a portion of the signal light towards corresponding detectors, each filter being configured to reflect a preselected waveband of light.

A method of microfluidic detection can include detecting, using an impedance sensor, an impedance of a fluid to indicate whether a threshold amount of fluid has been received in a reservoir of a microfluidic chip. The method can include initiating a test performed by the microfluidic chip on the received fluid when the threshold amount of fluid has been received.

A microfluidic diagnostic chip may comprise a main fluid channel comprising a main pump, a secondary fluid channel branching off from the main fluid channel, and a secondary pump within the secondary fluid channel wherein the secondary pump is to pull a particle of analyte of a first size from a fluid passing through the main channel, the fluid comprising particles of analyte of the first size and of a number of larger sizes. A method of analyzing an analyte on a microfluidic chip may comprise pumping, with a main microfluidic pump, a fluid comprising an analyte particle through a main microfluidic channel fluidly coupled to a fluid slot and sorting the analyte particle within the fluid through a secondary microfluidic channel by pulling the analyte particle into the secondary microfluidic channel with a secondary microfluidic pump.

Fluid may be pumped within a microfluidic channel across a cell/particle sensor using a microscopic resistor. The microscopic resistor may be selectively actuated so as to heat the fluid within the microfluidic channel to a temperature below a nucleation energy of the fluid so as to regulate a temperature of the fluid for at least when the cell/particle sensor is sensing the fluid.

A system and method for sorting sperm is provided. The system includes a housing and a microfluidic system supported by the housing. The system also includes an inlet providing access to the microfluidic system to deliver sperm to the microfluidic system and an outlet providing access to the microfluidic system to harvest sorted sperm from the microfluidic system. The microfluidic system provides a flow path for sperm from the inlet to the outlet and includes at least one channel extending from the inlet to the outlet to allow sperm delivered to the microfluidic system through the inlet to progress along the flow path toward the outlet. The microfluidic system also includes a filter including a first plurality of micropores arranged in the flow path between the inlet and the outlet to cause sperm traveling along the flow path to move against through the filter and gravity to reach the outlet.

A microfluidic device that reads a colloidal mixture and separates the colloids based upon size and shape. and in the case of polymer colloids such as DNA, it reads patterns of markers attached to DNA. The combination of different separated fractions and DNA markers (it mapping) constitutes the physical code.
