Microscale bioprocessing system and method for protein manufacturing from human blood
A bioprocessing system for protein manufacturing from human blood is provided that is compact, integrated and suited for on-demand production and delivery of therapeutic proteins to patients. The parent's own blood can be used as the source of cell extracts for the production of the therapeutic proteins.
1. A system for expressing and purifying a desired protein from blood, comprising:
a whole blood separator adapted for receiving whole blood and outputting (i) at least one blood fraction comprising at least one of erythrocytes, reticulocytes and lymphocytes and (ii) a plasma and unused portion fraction;
a blood cell lysing module adapted for receiving and lysing the at least one blood fraction from the whole blood separator and outputting a lysate;
a bioreactor, adapted for producing the desired protein utilizing cell-free protein expression, for receiving the lysate from the blood cell lysing module and producing the desired protein from the lysate via protein expression utilizing cDNA or mRNA for the desired protein; and
a purification module for receiving the desired protein from the bioreactor and purifying the desired protein.
2. The system of claim 1 , wherein the bioreactor has a capacity of 20 ml or less.
3. The system of claim 1 , further comprising a diafiltration component for receiving the purified desired protein from the purification module and for further purifying the desired protein.
4. The system of claim 3 , wherein the diafiltration component comprises: a product section for receiving purified desired protein from the purification module; and a buffer section for receiving a buffer solution.
5. The system of claim 4 , wherein the diafiltration component comprises:
a first substrate;
a second substrate; and
a diafiltration membrane positioned between the first and second substrates.
6. The system of claim 5 , wherein the diafiltration component further comprises
a flow cell; and
tubing positioned within the flow cell, wherein the diafiltration membrane comprises the tubing material.
7. The system of claim 1 , wherein the desired protein comprises a therapeutic protein and wherein the whole blood originates from a patient to whom the therapeutic protein will be administered.
8. The system of claim 5 , wherein the product section comprises a serpentine-shaped channel formed on the first substrate and the buffer section comprises a serpentine-shaped channel formed on the second substrate, wherein the first and second serpentine-shaped channels substantially correspond with each other.
9. The system of claim 1 , wherein the blood cell lysing module comprises at least one lysing reagent comprising EDTA.
10. The system of claim 1 , wherein the bioreactor further comprises a fluid storage/dispenser comprising at least one container selected from the group consisting of a holding container, a washing solution container, a lysing reagent container, a reaction solution container, and a buffer container.
11. The system of claim 1 , wherein the purification module comprises one of membrane chromatography or column chromatography.
12. The system of claim 1 , wherein the bioreactor further comprises at least one optical chemical sensor positioned inside the bioreactor.
13. The system of claim 1 , further comprising a first heating and cooling element positioned inside the bioreactor for controlling a temperature solution inside the bioreactor.
14. The system of claim 1 , wherein the system further comprises a processor for controlling and/or monitoring the bioreactor and the purification module.
15. The system of claim 1 , wherein the bioreactor further comprises a DNA port.
16. The system of claim 1 , wherein the lysate is cell-free.
17. The system of claim 1 , wherein the system further comprises a plasma and unused portion container in fluid communication with both the whole blood separator and a coupling unit, wherein the plasma and unused portion fraction is temporarily stored in the plasma and unused portion container.
18. The system of claim 17 , wherein the coupling unit is in fluid communication with either the purification module or, when present, a diafiltration component, for combining the purified desired protein with the plasma and unused portion fraction.
19. The system of claim 1 , wherein the blood cell lysing module comprises at least one of a mechanical lysis device, an osmotic shock lysis device, a high pressure shock lysis device or an electroporation lysis device.
