摘要:
Embodiments of the disclosure concern methods of determining the effectiveness of immune cells, such as T cells, with particular chimeric antigen receptors. In specific embodiments, a synapse between the CAR and the tumor antigen is measured for structure, signaling, and functionality by imaging. As such, the quality of the synapse is determined and positively correlates with effectiveness of the particular CAR immune cells.
摘要:
One aspect of the invention provides a method for fabrication of a membrane on a surface. The method includes: providing a surface interfacing two environments, wherein one of the environments is a liquid; providing a flow-recirculating fluidic device having channel exits in the liquid environment in proximity of the surface; and delivering locally one or more processing solutions. The one or more processing sources including one or more membrane sources adapted and configured to form a membrane on the surface.
摘要:
The present invention relates to a novel protocol for making a hydrogel, which shows increased stability compared to hydrogels of the art, and can be reliably reproduced. The hydrogels produced by the methods of the present invention are preferably three dimensional, and particularly suitable for the culture of stem cells.
摘要:
An improved agglutination immunoassay is characterized by reacting a sample fluid which may contain an analyte with a generic antibody conjugated to latex particles and then adding an antibody specific to the analyte to be determined. Agglutination resulting from adding the antibody specific to the analyte is measured and correlated with the amount of analyte in the sample.
