Specific embodiment
The present invention may be implemented in different forms, be not limited to the examples mentioned in the following.Following implementation
Example only as the present invention difference towards and feature in representative.
As shown in Figure 1, a kind of medical cell experiment process liquid configuration method successively includes that stoste prepares and stoste fusion two
A step, in which:
It is 20-50mmol/L that BSA solution that compound concentration is 45-50g/100ml and compound concentration are needed in stoste preparation process
Cardamom acid solution.
Specifically, the BSA solution that compound concentration is 45-50g/100ml includes: to be placed in the PBS buffer solution in centrifuge tube
It is heated in 60-65 DEG C of water-bath, when PBS buffer solution is heated to 60-65 DEG C, weighs BSA and be added in PBS buffer solution and be put in centrifugation
12-15min is centrifuged with the speed of 10000r/min on machine, until BSA is dissolved completely in PBS buffer solution, obtaining concentration is 45-50g/
The BSA solution of 100ml, BSA solution is placed in 60-65 DEG C of water-bath and is kept the temperature.
It should be noted that BSA may be dissolved in PBS buffer solution soon under high speed centrifugation, at this time, it is desired nonetheless to
It is centrifuged 12-15min.Meanwhile directly centrifugation mixing is not heated, or rock or shake and be likely to that BSA is caused to form lump shaped crystalline
It is insoluble, therefore, to avoid shaking in heating process.

It needs to reach the cooling rate of 40-80 DEG C/min to -20 DEG C, is quickly cooled down for mixing most important, otherwise later period solution meeting
There is cotton-shaped object.
2) it adjusts back PH: adding the enriching hydrochloric acid of 12mol/L to mixed liquor and be uniformly mixed, adjust the PH numerical value of mixed liquor
For 7.3-7.5, high lipoprotein solution is obtained；
It should be noted that due to using NaOH solution when dissolution, it is therefore desirable to adjust back PH.Solution is brown color after adjusting back PH
Sample is clarified, with former BSA solution character indifference, without any solid or cotton-shaped impurity, character is stablized.
3) it adds glucose: high lipoprotein solution being moved into centrifuge tube to be placed in 30-35 DEG C of water-bath and is heated, high lipoprotein solution adds
When heat is to 30-35 DEG C, weighs glucose and be added in high lipoprotein solution and be put on centrifuge 8- is centrifuged with the speed of 6000r/min
10min obtains that concentration of glucose is 1-5mol/L, cardamom acid concentration is 10- until glucose is dissolved completely in high lipoprotein solution
The high glucose and high fat cell experiment treatment fluid of 25mmol/L.
It should be noted that using the above method when small measurement, low concentration configure.When needs large dosage configuration, and
When glucose is 4-5mol/L, cardamom acid concentration is 18-25mmol/L, it is also necessary to be set between low-temperature mixed and readjustment PH operation
Ultrasonic mixing operation is set, ultrasonic mixing operation specifically includes: -20 DEG C of low-temperature mixed solution after hydrotropy are placed in 20-25 DEG C
Environment, and use the ultrasonic vibration 6-8min of 200-500W power.
