Publication number: 20100273240Abstract: The present invention relates to a method for production and purification of affinity tagged macromolecular complexes, such as ribosomes. More closely, the method comprises in-frame fusion of a nucleotide sequence specific for an affinity tag and a selection marker, wherein the fusion is at the chromosomal site of a gene encoding a multicopy protein, and wherein the macromolecular complex is expressed with multiple copies of said affinity tag. The invention also relates to affinity tagged ribosomes, to cells comprising such affinity tagged ribosomes, and to various uses thereof.Type: ApplicationFiled: November 18, 2008Publication date: October 28, 2010Applicant: GE HEALTHCARE BIO-SCIENCES ABInventor: Suparna Sanyal
