摘要 |
The present invention relates to a process and apparatus for purifying a molecule of interest from a heterogeneous clarified fluid mixture. The apparatus of the invention generally comprises a continuous perfusion fermentation system, a continuous particle removal system integrated with the perfusion fermentation system; and a continuous purification system integrated with the particle removal system, which is maintained under sterile conditions. The process comprises filtering a heterogeneous clarified fluid mixture by continuous ultrafiltration at a specific flow rate below the transition point of the molecule of interest in the pressure-dependent region of the flux versus TMP curve, wherein the specific flow rate is maintained substantially constant throughout the continuous ultrafiltration. |

1. An apparatus for separating a protein of interest from a heterogenous tissue culture fluid mixture, comprising:
(a) a continuous perfusion fermentation system adapted to continuously produce a tissue culture fluid containing a protein of interest at a substantially constant volumetric flow rate; (b) a continuous particle removal system integrated with and adapted to continuously receive the tissue culture fluid from the perfusion fermentation system and continuously produce a clarified tissue culture fluid; and (c) a continuous purification system integrated with and adapted to continuously receive the clarified tissue culture fluid from the particle removal system and continuously produce a product isolate containing the protein of interest; wherein the continuous purification system is an ultrafiltration system, wherein the ultrafiltration system comprises an ultrafiltration membrane having an area in square meters equal to a range of between 0.1 to 2 times the volumetric flow rate of the continuous perfusion fermentation in liters/hour and wherein the apparatus is maintained under sterile conditions. |
