Tagraíonn subculture don phróiseas chun an cultúr a roinnt ina chodanna beaga, iad a ath-ionaclú i soitheach cultúir eile (buidéal), agus ansin saothrú. Is earraí inchaite iad Fleascáin chultúir cille a úsáidtear go coitianta agus cealla á saothrú. Mar sin, conas na cealla sa fhleascán a fhoshaothrú?

Go ginearálta, fásann na cealla i bhfleascáin chultúr na cille ina monolayer dlúth agus go bunúsach tá siad sáithithe. D'fhonn a chumasú do na cealla leanúint ar aghaidh ag atáirgeadh agus ag leathnú líon na gcealla, is gá oibríochtaí pasáiste a dhéanamh. Is féidir cealla ar fionraí a scaradh go díreach, agus ní mór cealla greamaitheacha a dhíleá sular féidir iad a scaradh. Go ginearálta, úsáidtear einsímí próitéalaíocha (cosúil le trypsin) chun cealla greamaitheacha a dhíleá ina gcealla aonair. Is féidir aigéad ethylenediaminetetraacetic (EDTA) a chur leis freisin chun díleá a fheabhsú. Breathnaigh ar na cealla go dtí go n-éiríonn na cealla cruinn agus scaradh ó bhalla an bhuidéil. Is minic a thógann an próiseas seo 5-15 nóiméad. Chun cnuasacha cille a sheachaint, ná tapáil na fleascáin shaothrúcháin cille le linn an phróisis díleáite na gcealla. díleá a éascú. Tar éis na cealla a scaradh ó bhalla an bhuidéil, cuir meán iomlán ina bhfuil serum láithreach chun an díleá a stopadh. Is féidir le próitéiní áirithe sa serum bac a chur ar an briseán. Gníomhaíocht einsím. Go ginearálta, ní gá lártheifneoiriú. Má theastaíonn meán saor ó serum nó serum íseal ó na cealla, lártheifneoir ag 125000g ar feadh 5 nóiméad, ansin caith amach an meán scortha, cuir meán nua cuí leis agus déan na cealla a mheascadh go réidh roimh an bhfochultúr.

How to passage the cells in the cell culture flasks

Is é an cóimheas pasáiste cille go ginearálta 1:2 -1:20, ag brath ar an gcineál cille. Sa phróiseas pasáiste, déanfaidh trypsin damáiste do membrane cille roinnt cealla. Is féidir leat scraper cille a úsáid chun na cealla a scrapeadh go réidh, cuir méid cuí de mheán, go réidh pípéad chun na cealla a mheascadh, agus iad a aistriú chuig fleascán cultúir nua.

The cell passaging ratio is generally 1:2-1:20, depending on the cell type. In the process of passaging, trypsin will damage the cell membrane of some cells. You can use a cell scraper to gently scrape the cells, add an appropriate amount of medium, gently pipette to mix the cells, and transfer them to a new culture flask.

The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.

The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.

In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.

Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.

NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.

In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
