  • Patent number: 11851666
    Abstract: The present invention belongs to the field of biotechnology, specifically to the field of recombinant protein expression. The present invention focuses on two problems commonly encountered during recombinant protein expression, low quantity of protein expression and genetic instability of cell lines used for recombinant protein expression. The basic principle of the present invention is to introduce several expression cassettes into a cell which expression cassettes all code for the same mature recombinant protein of interest, but which expression cassettes have different nucleotide sequences. Expression cassette means a polynucleotide sequence which comprises at least a promoter sequence, a start codon, a polynucleotide sequence coding for a protein which is intended to be recombinant expressed (POI), a stop codon and a terminator.

  • Patent number: 11787846
    Abstract: EphA2 T-cell epitope are provided herein. The epitopes include peptides corresponding to specific fragments of human EphA2 protein containing one or more T-cell epitopes, and conservative derivatives thereof. The EphA2 T-cell epitopes are useful in an assay, such as an ELISPOT assay, that may be used to determine and/or quantify a patient's immune responsiveness to EphA2. The epitopes also are useful in methods of modulating a patient's immune reactivity to EphA2, which has substantial utility as a treatment for cancers that overexpress EphA2, such as renal cell carcinoma (RCC). The EphA2 epitopes also can be used to vaccinate a patient against EphA2, by in vivo or ex vivo methods.
