Abstract: The invention relates to a method of increasing protein expression in baculo vector virus expression systems. The invention provides a method to produce a recombinant protein in insect cell culture which comprises selecting a recombinant baculovirus expressing said protein, growing insect cells in growth medium in a culture vessel and infecting the cells with an inoculum of at least one baculovirus at a cell density of 1×105 to 5×106 cells/ml with an m.o.i of <0.01. The invention also provides a method to produce recombinant pestivirus E2 or Em9 protein or fragments thereof in insect cell culture characterized by a final concentration of the protein fragments in the growth medium at harvest of at least 100 ?g/ml. The invention also provides a method of producing recombinant FSH, ?-units and/or ?-units, and complexes and fragments thereof, at a concentration in the growth medium at harvest of at least 15 ?/ml.

The invention provides a method to produce a recombinant protein in insect-cell culture which comprises selecting a recombinant baculovirus expressing said protein, growing insect cells in growth medium in a culture vessel and infecting the cells with an inoculum of at least one baculovirus at a cell density of 1×105 to 5×106 cells/ml with an m.o.i of <0.01. The invention furthermore provides a method to produce recombinant pestivirus E2 or Em9 protein or fragments thereof in insect cell culture characterized by a final concentration of said protein (fragments) in the growth medium at harvest of at least 100 &mgr;g/ml. The invention furthermore provides a method to produce recombinant follicle stimulating hormone, &agr;-units an/or &bgr;-units and complexes and fragments thereof, at a concentration in the growth medium at harvest of at least 15 &mgr;l.

Abstract: A method for selecting eggs, in which the eggs are subjected to a Nuclear Magnetic Resonance (NMR) treatment for obtaining an NMR image and the eggs are selected on the basis of the NMR image.An apparatus for processing eggs includes egg supply means, egg selection means, and egg discharge means, the egg selection means having at least one apparatus for making at least one NMR image of an egg, and means being provided for controlling the egg discharge means on the basis of the at least one NMR image.
