Kempbio, Inc. has over 15 years of experience with the transient expression of recombinant proteins in suspension cultures of mammalian host cells at the 1-liter to 100-liter scale. We produce our own proprietary formulation of PEI which allows us to offer exceptional expression results at a reasonable cost. Transfections utilize either HEK-293 or CHO-S cells as the host cell for expression and both systems are scalable from 1-liter to 100 liters and above.
HEK-293 Cells Transfected Using PEI/DNA Complex: Viral Glycoprotein
Expression and purification of a secreted viral glycoprotein. Lane 3 represents the load for an affinity column and Lane 4 is the column flow-through fraction. Lanes 5 through 10 are elution fractions.
