An immunoassay includes forming first mixtures by reacting a combination reagent with serum of a subject; simultaneously forming second mixtures by reacting randomly selected platelet samples with the serum wherein in each mixture there are immunity compounds formed by combining the platelet antigens with predetermined antibodies in the serum, and other platelet antigens and other antibodies in the serum not forming the immunity compounds; preparing an interception device including receptacles and a filter net; placing each mixture in one receptacle; washing the mixtures wherein the mixtures forming the immunity compounds are intercepted by the filter net with others passing through; adding a signal sensing reagent to each receptacle; reacting the signal sensing reagent with the intercepted mixtures forming the immunity compounds to form final products; and performing a signal sensing to determine whether the final products contain anti-platelet antibodies and determine compatibility of cross matching of respective platelet samples.

A microfluidic chip for three-dimensional cell culture with high-throughput perfusion includes an array of cell culture units, each unit including a cell culture medium inlet hole connecting to one cell culture medium tank, at least one micro-bioreactor, at least one microchannel and at least one medium collection and analysis tank. Each medium collection and analysis tank is connected to an air chamber with an air channel and the air chamber has negative pressure source holes to generate negative pressure to drive the culture medium. The microfluidic chip also includes an intermediate plate connected to the bottom surface of the roof, and two bottom plates detachably assembled at the bottom of the intermediate plate. The first and second bottom surfaces have micro-bioreactors and cylindrical recessed slots and the intermediate plate has corresponding holes to achieve the goal of three-dimensional cell culture using minimum experimental resources with high-throughput perfusion.
摘要:
This present invention relates to a method for forming alginate microbeads. The method includes using a needle connected to a vibrator to continuously spot tiny alginate microdroplets in an oil layer. Subsequently, the temporarily formed alginate microdroplets sink into a CaCl2 solution to become gelled microbeads. As a whole, the method has opened up a route to perform alginate-microbead formation in a simple, continuous, controllable, uniform, cell-friendly, and less-contaminated manner.

A method of screening, isolating and purifying rare cells includes obtaining cell groups with rare cells from a sample, removing cells not to be screened from the cell groups, and drawing the remaining cells as a cell suspension sample. An introduction device is activated to load the cell suspension sample onto an optically-induced dielectrophoresis chip including a cell isolation zone having a division arrangement wherein at least one optical pattern is configured on the cell isolation zone for screening, isolating and purifying the rare cells. The at least one optical pattern is configured to migrate, rotate or both. The at least one optical pattern is activated to attract the rare cells into a collection tank on the chip, and a liquid drawing device is activated to draw the rare cells out of the collection tank, thereby obtaining purified rare cells from the sample.
