Expression and Production of Proteins—Service and Research

Proteos can produce your protein in your choice of expression systems

Baculovirus infected insect cells Sf9, Sf21, High Five* or Drosophila S2 cells Expression optimization studies BIIC’S (baculovirus infected insect cell stocks) production for baculovirus storage Cytoplasmic and secreted proteins Selenomethionine labelling Cell paste production Concentrated culture supernatant production > 100 liter capacities			*E. coli* Expression optimization – varying time, temperature, induction conditions or media additives. Stable isotopic labelling Cell paste production Inclusion body purification following your refolding paradigm or a referenced method 100 liter capacities in shake flasks

Mammalian cells HEK293, CHO (K1, S, DG44) and other cell lines Stable transfection pools Stable clonal isolation Transient transfection Stable isotope labelling with amino acids (SILAC) Cytoplasmic and secreted proteins Cell paste production Concentrated culture supernatant production > 100 liter capacities			Yeast Saccharomyces cerevisiae, Pichia,* Kluyveromyces* Cell paste production Supernatant concentration > 100 liter capacities in shake flasks
