  • Patent number: 10696997
    Abstract: A cassette sequence for the transformation of a host cell includes at least: a first nucleotide sequence encoding a peptide or protein of interest to be produced by the host cell. The first sequence is linked to a second nucleotide sequence providing resistance to a toxin or encoding an antitoxin peptide to the toxin. The nucleotide sequences are organized in such a way that production of the peptide encoded by the second nucleotide sequence(s) is translationally coupled to production of the peptide encoded by the first nucleotide sequence.

  • Patent number: 9890431
    Abstract: The present invention provides a method and a kit for detecting a S. pneumoniae nucleic acid in a sample. The method comprises the steps of isolating said nucleic acid and detecting hybridization between the S. pneumoniae nucleic acid and a labeled probe, wherein the detection of hybridization comprises detecting a change in signal from the labeled probe during or after hybridization relative to the labeled probe signal before hybridization. The method of the present invention is characterized in that said nucleic acid is a ribonucleic acid, which isolation comprises the addition of acidic phenol to said sample and the purification of said ribonucleic acid.

  • Patent number: 8877504
    Abstract: The present invention is related to a method for the selection of recombinant clones having integrated a gene of interest and a nucleotide sequence encoding a functional antidote protein to a toxic molecule, wherein said recombinant clones are the ones which survive following their integration into a host cell comprising in its genome a nucleotide sequence encoding said toxic molecule. The present invention is also related to a nucleic acid construct, a vector comprising said nucleic acid construct, a host cell and a cloning and/or sequencing kit for performing said method.
