摘要:
The present invention relates to methods for linking tetrazines with dienophiles to establish at least two linkages by sequentially performing at least two cycloaddition reactions. The methods in particular allow establishing multi-labeling strategies. In particular, the invention relates to methods for forming linkages by cycloaddition reactions, wherein the method comprises reacting a first alkyl-substituted tetrazine with a first dienophile comprising a irans-cyclooctenyl group followed by reacting a second tetrazine with a second dienophile comprising a cyclooctynyl group, wherein the reaction of the first tetrazine with the first dienophile proceeds in the presence of the second dienophile.
摘要:
The present invention relates to the field of microfluidics and in particular to methods for co-localizing a particle comprising DNA and/or RNA with a known barcode oligonucleotide. Thereby, the transcriptome or DNA of a cell can be barcoded and correlated to a cell phenotype or examined for the effect of a drug on the cell. The invention also provides microfluidic devices and systems having properties which make them particularly suitable for use in the methods of the invention.

The invention relates to archaeal pyrrolysyl tRNA synthetases lacking a nuclear localization signal and/or comprising a nuclear export signal. The invention also relates to polynucleotides encoding said pyrrolysyl tRNA synthetases, eukaryotic cells comprising said polynucleotide and tRNA acylated by the pyrrolysyl tRNA synthetase or a polynucleotide encoding such tRNA, methods utilizing said cells for preparing polypeptides comprising unnatural amino acid residues, and kits useful in said methods.
摘要:
In a light microscope (1) for cryomicroscopy comprising at least one objective (2) and a sample stage (3) having a cutout (7) for a coolable holder (8) for a sample carrier mount, wherein the cutout (7) is covered by a cover (6), the sample stage (3) is displaceable in two horizontal directions (4). The cover (6) lies on the sample stage (3) in a floating fashion and the objective (2) penetrates through a cutout (12) corresponding to the objective (2) in the cover (6). The method for cooling a holder (8) for a sample carrier mount in a light microscope (1) for cryomicroscopy by causing liquid nitrogen to flow through a cooling line (15) open at at least one end in the holder (8) is distinguished by the fact that the quantity of liquid nitrogen is dimensioned such that the entire nitrogen is present in gaseous form at the at least one open end (16) of the cooling line (15).
摘要:
The present invention relates to a compound having the general formula (V), optionally in the form of a pharmaceutically acceptable salt, solvate, polymorph, codrug, cocrystal, prodrug, tautomer, racemate, enantiomer, or diastereomer or mixture thereof, which are useful in treating, ameliorating or preventing influenza. Furthermore, specific combination therapies are disclosed.

The present invention relates to MafB mutants and uses thereof for research, screening and therapeutic purposes. In particular, the present invention relates to a MafB mutant polypeptide comprising the sequence as set forth in SEQ ID NO: 1 or 2 or a function conservative variant thereof wherein the glutaminic acid residue at position 269 has been deleted or substituted with a basic amino acid. The present invention also relates to a MafB mutant polypeptide comprising the sequence as set forth in SEQ ID NO: 1 or 2 or a function conservative variant thereof wherein the valine residue at position 277 has been deleted or substituted with a polar amino acid.
摘要:
The present invention is based on the discovery that large parts of the genome of nucleopolyhedtovirus (NPV)-alpha baculovirus clade Ia viruses can be deleted with out deleterious effect on the usability of the virus comprising such genome in the infection of cells in cell culture. Accordingly, the present invention provides NPY-alpha baculovirus clade Ia genome which is reduced in size in comparison to the respective native NPV-alpha baculovirus clade Ia genome, such genomes comprising heterologous nucleotides, viruses comprising either of these genomes, cells infected with such viruses and methods for producing such viruses and cells.
