Tá ról do-athsholáthair ag serum i bhfás agus iomadú cille i gcultúr na gceall, mar sin conas a bhíonn ról ag serum i gcultúr na gceall, agus cad iad na ceanglais maidir le pacáistiú media buidéal?
Feidhm Serum:
1. Is iad na príomhshubstaintí i serum próitéin, albaimin, etc., ar féidir leo pH an mheáin chultúir cille a mhaolánú agus an brú osmotic a chothabháil;
2. Is féidir le próitéiní ceangailteacha cosúil le próitéin aistritherin agus thyrocsín-cheangailteach vitimíní, lipidí, miotail agus hormóin eile, etc., a aithint agus is féidir iad a chomhcheangal le miotail tocsaineacha agus pirogens chun díthocsainiú;
3. Is féidir le fachtóirí fibronectin, fetuin agus greamaitheachta i séiream bó féatais greamaitheacht agus leathadh cille a chur chun cinn;
4. Is féidir le polaipeiptídí cosúil le fachtóir fáis pláitíní, fachtóir fáis fibroblast, fachtóir fáis eipideirm, fachtóir fáis nerve-chill, inslin, fachtóir fáis cosúil le insulin, somatotropin, hydrocortisone, etc. tacú le roinnt agus iomadú cille agus fás logartamach cealla a chothabháil;
5 . Is féidir le coscairí próitéáis mar mhacraglobulin próitéas a chosc agus cealla a chosaint ó dhamáiste;
6. Tá serum saibhir i aimínaigéid, glúcós, cetoaigéid agus riandúile in éineacht le próitéiní, a bhfuil brí acu ar fad do chultúr na gceall. de serum an-tábhachtach. I roghnú na buidéil serum, is gá go ginearálta an comhlacht buidéal a bheith trédhearcach, saor ó DNase, RNase, pyrogen agus substaintí eile a dhéanann difear d'fhás cille, agus séalaithe chun sceitheadh a chosc. Is fiú a thabhairt faoi deara gur gá serum a stóráil go ginearálta i dtimpeallacht de -5 ° C go -20 ° C, agus mar sin ní mór d'ábhar an bhuidéil mheán na saintréithe friotaíocht íseal teochta a chomhlíonadh freisin.
Requirements for media bottles:
Serum has complex components and important functions, so the preservation and use of serum is very important. In the selection of serum bottles, the bottle body is generally required to be transparent, free of DNase, RNase, pyrogen and other substances that affect cell growth, and sealed to prevent leakage. It is worth noting that serum generally needs to be stored in an environment of -5 °C to -20 °C, so the material of the media bottle must also meet the characteristics of low temperature resistance.
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.
