Cell factorysseasamh tábhachtach i gcultúr na gceall ar scála mór, a úsáidtear go príomha i gcógaisíocht, táirgeadh vacsaíní, teiripe cille agus réimsí eile. Tá cealla níos íogaire don timpeallacht táirgthe, agus mar sin tá na ceanglais maidir le hábhair inchaite sách ard freisin. Is braite bunúsach an-tábhachtach é braite bitheolaíoch, lena n-áirítear go príomha na nithe seo a leanas:
Triail cítotocsaineachta: Teagmhais íonmharaithe ceall de bharr cealla nó ceimiceáin nach bhfuil ag brath ar apoptosis nó neacróis mar mheicníochtaí bás cille. Tríd an tástáil seo, is féidir a mheas an bhfuil substaintí in amhábhair mhonarcha na gcealla nach bhfuil a chuidíonn le fás cille. freagairtí imdhíonachta sonracha a thabhairt dóibh. damáiste, ag taispeáint comharthaí agus comharthaí soiléire. Tríd an tástáil seo, is féidir a mheas an bhfuil an tsubstaint tástála ina ailléirgin agus an déine íograithe. Úsáidtear go coitianta i sainaithint Streptococcus, Vibrio, Diftéire, etc. Is féidir le go leor baictéir hemolysin a tháirgeadh, ar féidir leo an pláta a hemolyze, mar sin beidh fáinne hemolytic le feiceáil thart ar na baictéir seo. 648/2012 Téacs atá ábhartha maidir leis an LEE éifeachtaí díobhálacha féideartha an táirge nó a láiste ábhair a mheas le linn úsáid na feiste leighis. Toisc go bhféadfadh na sleachta seo dochar a dhéanamh d'fhíocháin nó d'orgáin nach bhfuil i dteagmháil dhíreach leis an táirge trí ionsú, dáileadh agus meitibileacht an chorp daonna.
Ina theannta sin, cuimsíonn an tástáil bhitheolaíoch freisin tástáil spreagtha intradermal agus tástáil imoibrithe intradermal. Tá na míreanna tástála seo go léir chun a chinntiú nach bhfuil substaintí a chuireann isteach ar fhás cille sa mhonarcha cealla, ionas go n-áiritheofar gnáth-iomadú cealla.
Hemolysis test: Hemolysis test is a method for screening and identification of bacteria specified in the national standard. Commonly used in the identification of Streptococcus, Vibrio, Diphtheria, etc. Many bacteria can produce hemolysin, which can hemolyze the plate, so a hemolytic ring will appear around these bacteria.
Systemic toxicity testing: The starting point of systemic toxicity testing is to consider the potential adverse effects of the product or its material leaching during use of the medical device. Because these extracts may cause harm to tissues or organs that are not in direct contact with the product through the absorption, distribution and metabolism of the human body.
In addition, the biological test also includes intradermal stimulation test and intradermal reaction test. These test items are all to ensure that the cell factory does not contain substances that affect cell growth, so as to ensure the normal proliferation of cells.
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.
