摘要:
The invention relates to one or more size-based separation modules adapted to increase a concentration of a first analyte in a sample by at least 10,000 fold, wherein said first analyte has an initial concentration in said sample of less than 1 x 10 -3 analytes/µL, and an analyzer for analyzing said first analytes in an enriched medium. Methods of using the separation modules for identifying a characteristic associated with a condition in a patient e.g. a fetal abnormality are also provided.
摘要:
The invention features devices and methods for the enrichment of cells and other desired analytes by employing a magnetic field, alone or in conjunction with size-based separation. The devices and methods may be advantageously employed to enrich for rare cells, e.g., fetal cells or epithelial cells, present in a sample, e.g., maternal blood.
