摘要:
The present invention relates to compositions and methods for screening and/or identifying compounds exhibiting biological activity on neurons. The invention also relates to the isolation and culture of neurons, methods of inducing pathological conditions to said isolated neurons, as well as kits for implementing said methods. The invention can be used in experimental research, drug discovery, drug development, and the like. More particularly, the invention can be used to identify and/or characterize and/or improve compounds which are active on neurons and can be used for treating disorders of the nervous system.
摘要:
The invention concerns methods and devices for observing or analysing samples on a support. More particularly, it concerns a device for sequential observation of several samples arranged on a common plate (19) comprising an objective (15) for observing a stage (17) for positioning the plate (19) adapted to ensure a relative displacement between the plate (19) and the observation axis in a plane perpendicular to the observation axis, while leaving free the vertical displacement along the observation axis, means (21) for illuminating the sample and means (23, 25) for acquiring an image at the objective (15) output. It comprises a spacer (43) fixed relative to the objective (15) and having a support surface (45) on the support (19), said support surface being located proximate to the observation axis, so that said spacer (43) is adapted to maintain, on the observation axis, a constant distance between the objective (15) and the observation surface (29), during a relative displacement between the support (19) and the observation axis. The invention is useful for rapid analysis of cell samples.
摘要:
The invention relates to a product to permit separation of cells in the domain of immunopurification and consisting of a finely divided carrier of a density lower than that of the medium from which such cells must be extracted, such carrier being covered with macromolecules capable of being specifically fixed to the cells to be extracted to which a privileged orientation was given to enable fixation of such macromolecules.
摘要:
The invention relates to a method of immunoassay for monoamines (molecules having a primary or secondary amine function) comprising chemical quantitative conversion of such amines into derivatives of higher molecular weight, which thereafter are brought into competition with radioactive analogous, or analogous carrying a tracer, for fixation to an antibody capable of recognizing all of them.
摘要:
Methods and equipment for forming multiple micro-depositions on surfaces from a single sample for sample analysis are provided. The device for the formation of micro-depositions of a liquid sample, includes a plurality of reservoirs, each with a through-hole, and needles, each with a tip mounted for movement through and beyond the hole, and a control member ensuring the controlled and regular formation of micro-depositions according to a defined profile.

摘要:
The invention relates to a device for positioning a biological sample analysis plate on an observation device comprising an observation lens and a chassis having a plate support assembly [20]. This assembly comprises a first frame [21] and a second frame [22] able to slide in a plane perpendicular to the observation axis, assumed to be vertical, with the first and second frames each able to move in a direction perpendicular to the direction of movement of the other frame; and a third frame [23] supported by the second frame [22] by means [30] used to maintain said third frame in a plane perpendicular to the observation axis, while leaving the movement free in a vertical plane.
