摘要:
A microtechnological device (6) for sampling cells on or in a tissue or other element of the body. It comprises a support (12) having at least one surface of interest (14) on which is present at least one recovery zone (10) comprised of a bottom wall (22) equipped with a plurality of protuberances (24). Preferably, the microtechnological device comprises at least one recovery zone covered with a coating that has the power to attract the cells to be sampled.
摘要:
A device (6) to sample molecules of biological interest is described. The device (6) includes capture zones (10) whose developed surface area is much greater than the surface so that sampling by contact allows a sufficient quantity of molecules to be obtained to achieve reliable analysis, whilst being sized so that the device (6) is neither invasive nor aggressive.In particular, the device comprises tiered capture zones (10) located on a support (12) fabricated using microtechnology techniques; the capture zones (10) may advantageously be functionalised.

摘要:
The present invention relates to a method of producing a recombinant protein comprising using a selection method other than antibiotics. In particular, it relates to a stable host/vector system based on the pyrC gene complementation designed to produce high level of heterologous recombinant protein in Escherichia coli. The expression system of the present invention allows rapid selection of plasmid containing cells during the cloning phases and lead to high protein expression during fermentation. This system has a strong selective efficiency, especially during the induction phase, leading to the selection of an almost homogeneous and stable plasmid bearing cell population. Moreover the productivity of the culture is to a large extent better than the one based on antibiotic resistance. This elevated vector stability combined with its high productivity fulfils the requirements for heterologous protein production in Escherichia coli to an industrial level.

The invention relates to novel silane compounds corresponding to the following formula (I): A-E-X (I) in which: X represents a silylated group which makes possible the covalent attachment of the silane compound to the hydroxyl or hydride functional groups of a support; E represents an organic spacer group; A represents a group capable of releasing an —OH functional group by acid hydrolysis, the said —OH functional group, after the said hydrolysis, being covalently bonded to E. Use of these silane compounds for functionalizing solid supports and for immobilizing biological molecules on these supports.
