  • Publication number: 20130157262
    Abstract: Provided is a method for selecting antibody-producing cell lines using a split fluorescent protein, and a kit for selecting antibody-producing cell lines. By using the split fluorescent protein to select the antibody-producing cell lines, the antibody-producing cell lines can be easily detected by observing whether a single fluorescent color derived from reassembly of the split fluorescent proteins is expressed, which leads in a drastic reduction in selection time and cost required to select highly productive antibody-producing cell line.

  • Patent number: 8080389
    Abstract: Disclosed herein are a Pichia pastoris-derived auto-inducible NPS promoter; a recombinant expression vector carrying the promoter and a nucleotide sequence, the sequence being operably linked to the promoter and coding for a recombinant protein; a host cell transformed or transfected with the recombinant expression vector; and a method for producing a recombinant protein, comprising culturing the host cell to express the recombinant protein and isolating the protein. The NPS promoter allows a recombinant protein of interest to be produced on a large scale without the need of any inducer.

  • Patent number: 7816509
    Abstract: Disclosed are a Pichia pastoris-derived translation elongation factor (TEF) promoter, a recombinant expression vector carrying the promoter and a heterologous protein encoding base sequence operably linked to the promoter, and a host cell transfected or transformed with the recombinant expression vector. Also, a method is provided for producing a heterologous protein. The method comprises culturing the host cell to express the Pichia pastoris-derived TEF promoter and isolating the promoter from the culture. The TEF promoter can be utilized for the mass production of heterologous proteins without the need for inducers.
