The cell culture parameter of related device: temperature: 36.5-37.5 DEG C, DO:50%-60%, pH:7.2-7.4, revolution: 40-60r/
Min is selected aerating system mode (Air/O2/CO2), is opened aerating system and is ventilated by intake interface to biological reactor
Culture.
Step 5, change liquid for 24 hours: when in biological reactor cell culture to for 24 hours after, stop stirring, stand 3-5 minute, adjusting
4 lower port of telescoping tube sampling height makes 4 lower port of telescoping tube sampling height at carrier ullage 0.5cm, discharge cell training
Then nutrient solution continues to cultivate by the cell maintenance medium that equivalent is added in fluid infusion 14.
The specific method of cell culture fluid is discharged in step 5: opening first switch valve body K1 and the 4th switching valve body K4, closes
Second switch valve body K2 and third switching valve body K3 are closed, aerating system is ventilated to tank body by intake interface and pressurizeed, and waste liquid is used
Bottle is used as receiving flask, and since pressure is greater than the pressure outside tank body in tank body, the culture solution of carrier ullage 0.5cm or more is being pressed
Probe tube is flowed through by telescoping tube under the action of power and constantly flows into receiving flask, until the liquid level of culture solution is lower than 4 lower end of telescoping tube
Stop when mouth sampling height;It is crossing air filtration head F1 respectively while closing first switch valve body K1 at this time and is making crossing air filtration head F2
It is inflated with syringe, the cell culture fluid in transparent observing area 61 and associated conduit part is squeezed into receiving flask.
Step 6, first switch valve body K1 and the cell observation: is opened after cell culture is to 48h, while being kept stirring
Three switching valve body K3 close second switch valve body K2 and the 4th switching valve body K4, use air-breathing in syringe crossing air filtration head F2,
The carrier and cell of biological respinse tank 1 stop pumping when flowing through transparent observing area 61, close first switch valve body K1, will

Stop when height;It is crossing air filtration head F1 respectively while closing first switch valve body K1 at this time and is using injection crossing air filtration head F2
Device is inflated, and the cell culture fluid in transparent observing area 61 and associated conduit part is squeezed into receiving flask.
Step 8, it after-crop antigen and changes liquid culture: after biological reactor cell culture is to 96h, stopping stirring,
3-5 minutes are stood, adjusting makes above 4 lower port of telescoping tube sampling height to carrier in tank at 0.5cm, again by sample tap 15
Culture supernatant antigen liquid is harvested, the second antigen liquid of harvest is set into the lower refrigerator-freezer freezen protective of -15 degree.
It collects the specific method of second of antigen: opening first switch valve body K1 and the 4th switching valve body K4, close second
Switching valve body K2 and third switching valve body K3, aerating system by intake interface to tank body ventilate pressurize, use antigen bottle as
Receiving flask, since pressure is greater than the pressure outside tank body, the work of the culture solution of carrier ullage 0.5cm or more in pressure in tank body
It probe tube is flowed through by telescoping tube is constantly flowed into receiving flask with lower, until the liquid level of culture solution is sampled lower than 4 lower port of telescoping tube
Stop when height;It is crossing air filtration head F1 respectively while closing first switch valve body K1 at this time and is using injection crossing air filtration head F2
Device is inflated, and the cell culture fluid in transparent observing area 61 and associated conduit part is squeezed into receiving flask.
Step 9, third time harvest antigen: after the cell culture in biological reactor is to 96-120h, adjusting revolution is
100-150 turns 3-5 minutes, then stops stirring, stands 3-5 minutes, is added by aerating system from intake interface to tank body ventilation
Pressure, open discharge pipe 2 on discharge valve 21 harvest filtered antigen, while open the snorkel 50 above filter screen into
Gas guarantees to harvest filtered antigen and keep sample to detect antigen valence, smoothly harvests antigen, the third that will finally harvest
Secondary antigen liquid sets -15 degree or less refrigerator-freezer freezen protective.
The utility model uses above technical scheme, and it is two that the heating method of biological respinse pot liquid, which is designed as reactor tank,
Layer, centre have collet to install heating tube 60, and the water of collet is constantly recycled by peristaltic pump, the liquid in the water heating tank of collet
Body.The pipe of sampling uses telescopic pipe in tank inner part, when culture carrier amount is big, is raised to pipe in removal waste fluid appropriate
Pipe is dropped to position appropriate in removal waste fluid when culture carrier amount is big by position, and carrier is unlikely to be discharged in this way.In tank
