摘要:
A method of tracking cell identity across analytical platforms uses stochastic barcoding (SB). SB uses a randomly generated code based on one or more of the number, color and position of beads encapsulated together with a set of cells of interest. SB use is demonstrated in an application where cells are transferred from a microwell array into a microtiter plate while keeping their identity, and obtained an average identification accuracy of 96% for transfer of 100 blocks. Model scaling of the method up to 1000 blocks demonstrated that SB is able to achieve approximately 90% accuracy.
摘要:
The present disclosure provides technologies for achieving cell patterning, as well as patterned cell arrays achieved with such technologies. Provided apparatus and methods are useful in a variety of contexts and provide particular advantages with respect to assessing living cell arrays and/or their responsiveness to stimuli, including identifying and/or characterizing complex cellular responses.
摘要:
A system for providing fully automated image segmentation and quality control of a protein array with no human interaction is presented. The system includes a memory and a processor configured by the memory. The processor is configured to receive an image file of the protein array, to geometrically distinguish a first block within the image, register a nominal location of the first block to the image by assigning a geometric code identifying the first block, draw a plurality of grid line on the array to delineate the first block from a second block, iteratively cluster a sub image for each feature in the delineated blocks to define a foreground area and a background area, identify pixels containing an artifact for each feature, and extract and return the signal intensity, variance, and quality of background and foreground pixels in each feature.
