The specific embodiment
Experimental technique:
1. cell recovery
1) take out cryopreservation tube from liquid nitrogen container, directly drop in 37 ℃ of warm water, and frequently shake and make it melt as early as possible.
2) take out cryopreservation tube from 37 ℃ of water-baths, with suction pipe sucking-off cell suspension, inject centrifuge tube and add culture fluid more than 10 times, low-speed centrifugal after mixing is abandoned supernatant, then is repeated to wash once with culture fluid.
3) with after the suitable dilution of culture fluid, the inoculated and cultured bottle is placed on 37 ℃ of standing cultivations of incubator, changes culture fluid next day, continues to cultivate.Go down to posterity when being cultured to finite concentration.The PANC-1 cell culture is in containing the DMEM high glucose medium of 10%Gibico hyclone, and SMMC-7721 and HepG2 cell culture contain 100U/ml penicillin and 100 μ g/ml streptomycins in culture medium in containing the DMEM high glucose medium of 10% hyclone.
2. passage is cultivated
The situation of observation of cell growth every day is grown to approximately 90% and is gone down to posterity when converging in culture bottle when cell, approximately went down to posterity once every 2-4 days.One bottle goes down to posterity into three bottles, or a 25cm
2Go down to posterity in a 75cm
2Culture bottle in.Method:
1) with 1 * phosphate buffer washed cell once.
2) add 2-3ml trypsinization liquid digestion, be placed in 37 ℃ of incubator numbers minute.Pat Tissue Culture Flask with hands, make cell separation.
3) suitable culture medium with the Gibico hyclone that contains 10-15% stops trypsinization.Cell is sub-packed in new culture bottle, continues to cultivate.
3. cell cryopreservation
1) get the cell tryptase protease digestion that is cultured to exponential phase, be collected in centrifuge tube and counting, centrifugal.
2) reject trypsin and old culture fluid add the frozen culture fluid (containing 10%DMSO, 40%DMEM and 50%Gibico hyclone) that configures, and in cryopreserving liquid, the ultimate density of cell is 0.5-1 * 10
7/ ml.Blow and beat gently with suction pipe and make cell even, then be distributed in aseptic cryopreservation tube, every pipe adds 1-1.5ml.
3) cryopreservation tube is put into freezing storing box and put-80 ℃ of quick-freezings, move in liquid nitrogen container after 5 hours and preserve.
4. medicine is prepared:
Herba chloranthi japonici alcohol F is dissolved in DMSO (dimethyl sulfoxide), and the mother solution that is mixed with 100mM or 50mM is standby.
Embodiment 1MTS method is measured Herba chloranthi japonici alcohol F to the growth inhibited effect of hepatoma carcinoma cell
HepG2 (available from ATCC) 3 * 10
3/ hole is seeded to 96 orifice plates, cultivate made it in 24 hours to add after adherent Herba chloranthi japonici alcohol F (available from
Shanghai Pharmaceutical Inst., Chinese Academy of Sciences), establish 6 Concentraton gradient, each concentration is established 3 multiple holes.Cell is at 37 ℃, 5%CO
2Cultivate after 72 hours under condition, outwell culture fluid, measure cell survival rate with MTS test kit (Promega company).
Method of testing is: cell is washed one time with serum-free medium, added the MTS chromophoric solution (adding 2ml solution 1 and 100 μ l solution 2 in the 10ml serum-free medium, fully mixing) for preparing in advance according to the amount of 100 μ l/well.Do not have the hole of cell to be made as this bottom outlet with one, absorb in order to the bias light of calibration solution.Cell is put into cell culture incubator to be continued to cultivate 2～4 hours, then read absorbance value (reference wavelength 630-700nm with microplate reader, measure wavelength 490nm), calculate cell survival rate, to measure hole absorbance value/control wells absorbance value as the numerical value of cell survival rate.According to cell survival rate, calculate Herba chloranthi japonici alcohol F to the IC50 value of HepG2 cell.
IC50 refers to a suppressed half
InhibitorConcentration.Here be the HepG2 cell quantity and be the concentration of a half Herba chloranthi japonici alcohol F of contrast.The calculating of IC50 generally need to be measured the dosage effect more than 5, then obtains function calculation by curve fitting and get.
Result: Herba chloranthi japonici alcohol F is 0.62 μ M to the IC50 value of HepG2 cell.
The test SMMC-7721 cell (available from Chinese Academy of Sciences's cell bank) that uses the same method, Herba chloranthi japonici alcohol F is about 9.37 μ M to the IC50 value of SMMC-7721 cell as a result.
The growth inhibited effect of embodiment 2 Herba chloranthi japonici alcohol F to human pancreatic cancer cell
Utilize cck-8 test kit (Japanese colleague's chemistry institute) to detect.
Step:
1) PANC-1 cell (available from Chinese Academy of Sciences's cell bank) is planted in 96 orifice plates uniformly, every porocyte number is 3 * 10
3Individual.
2) treat adherent, the rear dosing of spending the night, dosing (Herba chloranthi japonici alcohol F concentration be respectively 50,16.67,5.56,1.85,0.62 μ M), each concentration has 3 multiple holes.
3) cultivated 48 hours, complete medium is replaced to the mixture (10: 1) of serum-free medium and CCK8, hatched 2 hours in 37 ℃ of incubators.
4) take 450nm as measuring wavelength, take 650nm as the contrast wavelength, measure reading on microplate reader.
Result: Herba chloranthi japonici alcohol F is 7.82 μ M to the IC50 value of PANC-1 cell.
The growth inhibited effect of embodiment 3 Herba chloranthi japonici alcohol F to human breast cancer cell
Method according to embodiment 2 detects Herba chloranthi japonici alcohol F to the effect of MCF-7, and result shows that Herba chloranthi japonici alcohol F is 460 μ M to the IC50 value of MCF-7 cell.
