The method according to this invention, ginseng callus cell can be cultivated (substratum osmotic pressure, cold acclimation are gone down to posterity, improve in acceleration) to this cell in advance with before protective material mixes.This protective material and pre-cultured cell are by 1: 1-1: 3 volume ratio is mixed.
A kind of method of the cell growth that recovers to preserve comprises according to the present invention
1) at 40-60 ℃ of cell that thaws and preserve,
2) in substratum, cultivate the cell that thaws.
The invention still further relates to a kind of ginseng callus cell of preservation.
Fig. 1 is the schema of genseng callus cell of the present invention freeze-drying and cryopreservation method.
1. the present invention has adopted the freeze drying Techniques of preserving successfully to preserve ginseng callus, has Simple to operate, economical rationality, can preserve in enormous quantities the refrigeration material advantage.
2. the present invention has adopted the ultralow temperature Techniques of preserving successfully to preserve ginseng callus, has behaviour Do to recover the fast advantage of growth behind simple, the cell cryopreservation.
3. the present invention uses trehalose to preserve the protective agent component as plant cell, supports as plant germplasm The cell in source is preserved protective agent, particularly ginseng callus cell and is preserved protective agent, at present also not yet Report is arranged.
4. the invention provides desirable vitrifying protective agent, trehalose can with glycerine, DMSO, Be mixed with composite protectant in sucrose, glucose, bright skim milk, the proline and select each component Good combination makes the easier vitrifying state that enters of cell.
Embodiment
Further specify the present invention below in conjunction with embodiment.
Embodiment 1:
Treat the preparation of frozen material: use fluid suspension culture, callus cell is advisable to cultivate 5~7 days; Use solid culture, callus cell is advisable to cultivate 10~15 days.
Embodiment 2:
Protective material preparation: get trehalose, sucrose, glucose, bright skimmed milk, proline(Pro) and prepare the 1-6 protective material respectively, 1,2,4,5, No. 6 protective material uses the dissolving of 67V liquid nutrient medium, and No. 3 protective material directly uses bright skimmed milk dissolving.Carrying out freeze-drying and very low temperature respectively preserves.Each concentration is as follows:
No. 1 protective material: 5% DMSO, 10% glycerine
No. 2 protective materials: 20% sucrose, 5% DMSO, 10% glycerine
No. 3 protective materials: bright skimmed milk, 5% DMSO, 10% glycerine
No. 4 protective materials: 1.0M proline(Pro), 5% DMSO, 10% glycerine
No. 5 protective materials: 10% trehalose, 5% DMSO, 10% glycerine
No. 6 protective materials: 10% trehalose, 10% sucrose, 5% DMSO, 10% glycerine
Embodiment 3:
The pre-cultivation: get and treat that frozen material cultivates in advance in the substratum that adds trehalose, sucrose, glucose, bright skimmed milk, proline(Pro) composition; when filling a prescription freeze-stored cells as pressing 5, No. 6 protective materials; 25 ℃ of pre-3d that cultivate in the 67V substratum that adds 5%DMSO and 5% trehalose, 4 ℃ of pre-1d that cultivate in 5%DMSO and 10% trehalose 67V substratum again.
Embodiment 4:
The lyophilize store method: the volume mixture that (0 ℃) protective material and pre-cultured cell are pressed 1:3 on ice bath at first, its concentration is 1/4 of original content, slowly adds, and stirs gently, inhales behind the 10min and removes liquid.Then, ice bath is handled 5min in the protective material of original content, is that 1ml is sub-packed in the cillin bottle with every freeze pipe cell and protectant cumulative volume at last, and it is interior after pre-freeze to put Freeze Drying Equipment ,-28 ℃ of lyophilize 22h, and taking-up is put in-20 ℃ of refrigerators frozen.
Embodiment 5:
Cryopreservation method: at first (0 ℃) protective material and pre-cultured cell were by 1: 3 volume mixture on ice bath, and its concentration is 1/4 of original content, slowly added, and stirred gently, inhaled behind the 10min and removed liquid.Then, ice bath is handled 5min in the protective material of original content, and is last, is that lml is sub-packed in the frozen pipe of plastics with every freeze pipe cell and protectant cumulative volume, falls 1 ℃ with per minute, and extremely-50 ℃ are dropped in the liquid nitrogen frozen rapidly.
Embodiment 6:
Cell after frozen among the embodiment 4 is put into the liquid scrubbing substratum wash 10min, should dilute gradually during washing, the liquid scrubbing substratum is inhaled for the used 67V liquid nutrient medium of pre-cultivation and is removed washings, the liquid scrubbing substratum need place 0 ℃, and washing back cell changes over to and recovers on the used 67V solid medium of pre-cultivation to cultivate.Observation of cell recovers growing state.The cellular-restoring well-grown.
Embodiment 7
1min in 60 ℃ of water-baths thaws fast with the cell after frozen among the embodiment 5, cell mass is put into the liquid scrubbing substratum wash 10min, should dilute gradually during washing, the liquid scrubbing substratum is inhaled for the used 67V liquid nutrient medium of pre-cultivation and is removed washings, the liquid scrubbing substratum need place 0 ℃, and washing back cell changes over to and recovers on the used 67V solid medium of pre-cultivation to cultivate.Observation of cell recovers growing state.The cellular-restoring well-grown.
Presentation of results of the present invention:
Observe in the present invention when using 1,2,3,4,5, No. 6 protective material, adopt lyophilize and ultralow warm therapy depositary to join callus cell respectively, after through 0-6 month preservation period, thaw and cultivate again, the growth of part cellular-restoring is all arranged.But, use 5, No. 6 protective materials by freeze-drying and ultralow warm therapy preserve thaw after, the cellular-restoring phase is short, growth is very fast, just can be observed cell fission after week at 5-6 and grows fresh and tender new cell, and be better than for No. 6 No. 5.And use the 1-4 protective material by freeze-drying and ultralow warm therapy preserve thaw after, the cellular-restoring phase is longer, there is browning in various degree in cell, it is slower grow, at 8-10 after week, even for more time, just can observe cell fission and grow fresh and tender new cell.The present invention also observes and uses 5, No. 6 protective materials, preserves suspended culture cell by freeze-drying and ultralow warm therapy simultaneously, and ultralow warm therapy cellular-restoring growth is fast than lyophilization.
Description of test adopts the protective material that contains trehalose, be feasible with lyophilization and the frozen ginseng callus cell of ultralow warm therapy, and effect is fine.
When observation of cell recovers growth, because at present the most frequently used TTC method and FDA method detect cytoactive, the comprehensive action of enzyme in certain in the just cell that detects, and real cytoactive, also need keep cyto-architectural integrity, though very high through the relative survival rate of TTC method and the detection of FDA method, but be inoculated on the recovery media, may can not recover growth at all, illustrate that the endomembrane system of cell or other structures have suffered irreversible fatal damage.Therefore, adopt the most direct, the strongest, as to have actual value most method in the present invention, both the ratio of growth was recovered for judging the cell survival index in the frozen back of observation of cell.
