摘要:
The present invention relates to the qualitative and quantitative validation of marker indices, especially for medical diagnosis and particularly for the determination of the growth fraction in a sample with antibodies against the Ki-67 protein. Diagnostic kit for the quantification of a cell fraction labeled by a marker for in vitro diagnosis, characterized in that a pseudo-tissue is used for the intra- and inter-assay standardization of the marker index.

The invention provides a manually operated or automated clamping means to seal a solid support substrate to a solid support cover creating a uniform environmental chamber above a specimen mounted to the support substrate. The clamping means may consist of several components that may act ad a system to provide a repeatable and uniform clamping load to the substrate and cover.

摘要:
An apparatus for processing at least one biological sample accommodated on at least one carrier member (15) in a chamber includes, at least one reservoir (18) able to accommodate a fluid on a surface inside the chamber adjacent to and/or facing a substantial part of the at least one biological sample. The apparatus may comprise a bottom member (12) arranged to support at least one carrier member (15) carrying at least one biological sample and a lid (14) including at least one fluid reservoir (18). The reservoir filled with water provides humidity to the chamber and impedes drying out of the sample.
摘要:
An apparatus for introducing a specimen into a flow cytometer comprises: a syringe having a hollow barrel containing the specimen, a plunger partially within the barrel and a needle that extends into a volume of a nozzle of the flow cytometer; a one-way port in the nozzle forming a seal against the needle; a mounting platform coupled to both the syringe and to the flow cytometer; and a syringe pump coupled to the plunger, the syringe pump comprising a motor, a drive mechanism coupled to the motor; and a clamping mechanism coupled to the drive mechanism, wherein the motor operates the drive mechanism so as to cause the clamping mechanism to depress the plunger into the barrel.
摘要:
The invention relates to a method for detecting an infection of a mammal with an acid-resistant microorganism, wherein (a) a stool sample of a mammal is incubated with at least two different monoclonal antibodies, fragments or derivatives thereof or aptamers under conditions allowing a complex formation of antigens of the acid-resistant microorganism with antibodies, fragments or derivatives thereof or the aptamers, and wherein (aa) the first monoclonal antibody or the fragment or the derivative thereof or the first aptamer specifically binds an epitope of the first antigen, which shows at least with some mammals a structure after the intestinal passage that corresponds to the native structure or the structure which a mammal produces antibodies against after being infected or immunised with the acid-resistant microorganism or an extract or lysate thereof or a protein therefrom or a fragment thereof or a synthetic peptide; (ab) the second monoclonal antibody or the fragment or the derivative thereof or the second aptamer specifically binds an epitope of a second antigen differing from the epitope of the first antigen, which shows at least with some mammals a structure after the intestinal passage that corresponds to the native structure or the structure which a mammal produces antibodies against after being infected or immunised with the acid-resistant microorganism or an extract or lysate thereof or a protein therefrom or a fragment thereof or a synthetic peptide, wherein the parts of the mammals may overlap according to (aa) and (ab) and in total essentially make up the overall number of infected mammals; and (b) the formation of at least one antigen-antibody complex or antigen-aptamer complex according to (aa) or (ab) is detected.
摘要:
The present invention concerns an apparatus for automatic processing at least one biological sample accommodated on a carrier member, such as a slide by applying a predetermined amount of reagents in a predetermined sequence according to a processing protocol, said apparatus comprising; a housing frame; at least one processing section for accommodating at least one slide, the at least one processing section is provided within the housing; a hood cover protecting the at least one processing section in said housing; wherein the hood cover completely encloses the processing section defining an interior space; and wherein the apparatus further comprises climate control device provided to control the environment within the interior space.
摘要:
The present invention relates to monoclonal antibodies against the human Mcm3 protein, hybridoma cell lines, that produce such antibodies, procedures for the production and their use, pharmaceutical compositions comprising a monoclonal antibody according to the present invention, their use for the prevention and treating of certain diseases and well as methods relating to the prevention and treatment of diseases associated with Mcm3 expression. Monoclonal antibodies according to the invention detect and bind human Mcm3 monospecifically both in immunohistological and immunobiochemical detection systems. The process for the production of these monoclonal antibodies comprises an initial screening of excess hybridoma supernatant with immunobiochemical methods followed by a second screening of positive hybridoma by means of an immunohistochemical method.
