Assay wells with hydrogel as a well-contents separator

In a polymer assay cartridge having wells containing reagents, beads and sample, where the wells are covered (e.g., with Parafilm® or films) and shipped to the point of care, the reagents and well contents can leak out. The reagent solutions are made semi-solid by adding hydrogel reagents and cooling to form a gel. Preferably, the hydrogel is heated before an assay is conducted with the cartridge, and pigmented beads in the wells indicate melting or excessive heating, or congealing of the hydrogel, based on pigment color change.

Provided is an autologous culture method of autologous stem cells according to an embodiment of the present disclosure, the autologous culture method including: (a) accommodating one's own stem cells collected by a medical institution and a first culture medium in a first culture container from the medical institution to a one's own culture device; (b) controlling the culture device to establish an environment suitable for culture of stem cells; (c) observing the stem cells cultured in the first culture container of the culture device; (d) replacing the first culture medium in the first culture container; (e) separating cultured stem cells from the first culture container; and (f) accommodating separated stem cells in a second culture container with a second culture medium. Accordingly, as an individual cultures one's own stem cells by oneself, costs may be remarkably reduced, a replacement of one's own stem cells with other's stem cells may be fundamentally prevented, and an environment suitable for the culture of one's own stem cells may be provided.

Instruments, devices and consumables for use in a workflow of a smart molecular analysis system

A system for performing a molecular analysis workflow includes a reaction holder or a reaction substrate, such as a multi-well reaction plate, with a reaction holder/substrate RFID tag, and/or a reagent container with a reagent container RFID tag, and an instrument and/or device that includes an RFID reader/writer operable to read and/or write information to and from the reaction holder/substrate RFID tag and/or the reagent container RFID tag. The reaction holder/substrate RFID tag and the reagent container RFID tag can be utilized separately or together to send and receive and store information, for example, for a workflow of a molecular analysis, such as a polymerase chain reaction (PCR).
