I-Serum ibhekisela oketshezini lwe-colloidal olusuka ku-plasma ngemva kokukhipha i-fibrinogen, okuhlanganisa i-fetal bovine serum, i-calf serum, i-serum yezinkomo yabadala, neserum yehhashi. I-Serum ivamise ukugcinwa kokuthi media ibhodlela ezinikele futhi ibekwe endaweni yokugcina ehambisanayo ngokohlobo. Izinto ezithinta ikhwalithi ye-serum zifaka lokhu okulandelayo:
1. I-Endotoxin
Izinga lasekhaya alikho ngaphezu kuka-5EU/ml. I-Endotoxin iyingxenye yodonga lweseli ngemva kokuphuka kwamagciwane, ngakho izinga lokuqukethwe kwe-endotoxin lingabonisa ukusebenza kwe-aseptic ochungechungeni lwezinqubo ukusuka ekuqoqweni kwegazi kuye ekukhiqizweni. Uma okuqukethwe kwe-endotoxin kuphezulu kakhulu, kubonisa ukuthi i-serum ingcolile.
2. Isamba sokuqukethwe kwamaprotheni
Ububanzi obujwayelekile be-serum ye-fetus bovine ngu-30-40mg/ml. Uma inani liphezulu kakhulu, kusho ukuthi iminyaka yenkomo yayindala kakhulu, hhayi i-fetus bovine, futhi inani liphansi kakhulu, okubonisa ukuthi i-serum ingase ihlanganiswe namanzi.
3. I-Hemoglobin
Izinga alikho ngaphezu kuka-20mg/dl, umbala ubabomvu kakhulu, inani liphezulu, futhi okuphambene nalokho, liyancipha inani.
4. pH
I-serum yasekhaya ingaphezulu kakhulu kuka-7.5, kanti i-serum ye-fetus bovine engenisiwe ngokuvamile ingaphansi kuka-7.5. Isizathu esiqondile asaziwa futhi singase sihlobane neminyaka yenkomo. Lokhu kungasetshenziswa futhi ukuhlonza umthombo we-serum.
5. Ama-Microorganisms
Kuhlanganisa amagciwane, isikhunta, i-mycoplasma, i-bacteriophages, amagciwane ahlukahlukene e-pathogenic, njll. Phakathi kwazo, i-Escherichia coli ayinawo umthelela omncane kukhwalithi ye-serum, namagciwane e-pathogenic, ikakhulukazi i-BVDV, akhona cishe ku-90% we-serum yasekhaya, futhi lawa ma-microorganisms abaluleke kakhulu. Esinye sezici ezibalulekile zekhwalithi ye-serum yasekhaya.
Okungenhla ithonya lezici zayo kwikhwalithi yenqubo yokukhiqiza i-serum. Ngaphezu kwalokho, ikhwalithi yebhodlela lemidiya izophinde ibe nomthelela othile ku-serum. Uma ibhodlela lemidiya lingavalwanga ngokuqinile noma ukuvala inzalo kungaphelele, kuzoholela ngokuqondile ekungcolisweni kweserum. Ukusetshenziswa kwe-serum engcolile ekuhlolweni kweseli kuzonciphisa noma kumise ngisho nokukhula kwamaseli, okuzophazamisa umphumela wokuhlola.
Ngakho-ke, lapho ukhetha i-serum, kuyilapho uhlonza ikhwalithi ye-serum, qaphela ukuthi uphawu lwebhodlela lemidiya luqinile ukuze kuqinisekiswe ukuthi izinga le-serum lihle.
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.
