The invention relates to a sample holder (1) for a microscope comprising a transparent outer reservoir (2) and a transparent inner tube (3), which is arranged in the outer reservoir (2) to be rotatable. The invention further relates to a method for observing a specimen (23), comprising placing a specimen (23) in an inner tube (3), placing the inner tube (3) in an outer reservoir (2), dispersing an immersion fluid (20), which has a refraction index corresponding to the refraction index of the inner tube (3), between the inner tube (3) and the outer reservoir (2), locating the outer reservoir (2) in the light path of a microscope, and rotating the inner tube (3) to observe the specimen (23) at any desired perspective. Additionally, the invention relates to a microscope stage adaptor and to the use of a sample holder (1) for obtaining images.
摘要:
The invention relates to a method and a prokaryotic cell for identifying a compound, which interferes with ribosome biogenesis, assembly and/or degradation. The cell expresses a first fusion protein comprising a protein of a small ribosomal subunit, an amino acid linker and a first fluorescent protein, and a second fusion protein comprising a protein of a large ribosomal subunit, an amino acid linker and a second fluorescent protein. The invention further relates to a gene construct comprising a first element encoding a protein of a small ribosomal subunit fused to a first fluorescent protein by an amino acid linker, and a second element encoding a protein of a large subunit of a ribosome fused to a second fluorescent protein by an amino acid linker.
摘要:

In addition, the invention relates to a method for detecting a compound in a sample. The invention further relates to a biosensor for detecting a compound comprising an electrode system, a device for measuring electron transfer in the electrode system, and a microorganism.
摘要:
The present disclosure provides methods of treating a disease in a non-rodent mammal comprising administering to the cerebrospinal fluid (CSF) of the non-rodent mammal an rAAV2 particle containing a vector comprising a nucleic acid encoding a therapeutic protein inserted between a pair of AAV inverted terminal repeats in a manner effective to infect an ependymal cell in the non-rodent mammal, wherein the ependymal cell secretes the therapeutic protein so as to treat the disease.
摘要:
The invention relates to an antibody specific to Erk1/2 phosphorylated at Thr188 and a method for producing the same. The invention also relates to an in vitro method for determining the presence of phosphorylated Erk1/2 in a sample using the antibody of the invention. Therefore, the invention also comprises an assay for diagnosing a heart disease in vitro comprising the antibody of the invention and certain uses of the antibody. Moreover the invention relates to a peptide used to produce the antibody.
摘要:
The subject invention pertains to controlled-release dosage forms of anabaseine compounds, such as 3-(2,4-dimethoxybenzylidene)-anabaseine (also known as DMXBA or GTS-21) or a pharmaceutically acceptable salt thereof, methods of use, and methods for producing controlled-release dosage forms.
摘要:
The present invention relates generally to a method of amplifying a nucleic acid region of interest and, more particularly, to a method of amplifying a nucleic acid region of interest via a nested single tube PCR. The method of the invention is designed to provide a means to selectively inactivate the functionality of the outer primer or primers via an antisense nucleic acid molecule targeted to at least one of the outer primers, thereby maintaining amplification efficiency throughout the reaction. The development of a means to achieve efficient amplification by the outer primer followed by efficient amplification with the inner primers, in the context of a single tube nested PCR, is useful in a range of applications including, but not limited to, the diagnosis and/or monitoring of disease conditions which are characterised by specific gene sequences and the characterisation or analysis of specific gene regions of interest. Still further, the method of the present invention enables quantification to be performed and not just simple detection.
摘要:
The invention relates to a perylene diimide derivative and to an in vitro method for preparing the same. In addition, the invention relates to a method for detecting heparin in a sample using perylene diimide derivatives, wherein the interaction of the perylene diimide derivative with heparin modulates the intensity of the fluorescent signal of the mixture compared to the solution. The invention also comprises a diagnostic kit for detecting heparin in a sample in vitro, comprising the perylene diimide derivative, as well as the use of the perylene diimide derivative for neutralizing the anticoagulant activity of heparin.
