    摘要: 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).
