Ifektri yamaseliubuchwepheshe bezamasiko budlala indima ebalulekile kusikompilo lwamaseli olukhulu njengokuthuthukiswa komgomo kanye nemithi ye-biopharmaceuticals. Kudingeka izixazululo ezihlukahlukene zesiko lamaseli, futhi isilondolozi se-PBS singesinye sazo.
PBS isifinyezo sesiNgisi se-Phosphate Buffered Saline Solution. Ngokuvamile, amalungiselelo e-biological asebenzayo ahlanjululwa ngayo, futhi igciwane le-pseudorabies lingahlanjululwa nalo. Lokhu kungenxa yokuthi ibhafa ye-PBS inomphumela olungisekayo wokubhafa we-pH kanye nomthelela wokulinganisa usawoti. Isizathu sokungasebenzisi amanzi a-distilled ukuthi amanzi abhubhisa isakhiwo kanye nezinto eziphilayo zamaprotheni e-biological; isizathu sokungasebenzisi i-saline evamile ukuthi ayikwazi ukulungisa i-pH. Ngakho-ke, ukukhetha kokuqala kokugeza amaseli ebhayoloji yibhafa ye-PBS. I-PBS ayiyona i-panacea. Ukugcina izimo ezifanele kuqinisekisa ukuthi izinto eziphilayo eziphilayo zigcina izici zazo eziphelele kakhulu. Ezinye izinto eziphilayo ezisebenzayo zidinga izimo eziphakeme kune-PBS. Kulesi simo, ezinye izithako zidinga ukwengezwa.
Inani le-pH lebhafa ye-PBS iwububanzi benani le-pH elifaneleka kakhulu lamaseli, futhi inani le-pH ngokuvamile alishintshi ngaphansi kokukhuthazwa kwenani elincane le-asidi ne-alkali. . Ngokuvamile, inani le-pH yendawo ephakathi kulula ukulishintsha, elilimaza kakhulu amaseli, kodwa isilondolozi se-PBS singagcina amaseli enempilo futhi akhule ngaphakathi kwebanga le-pH elifanele. Ngemva kokuthi amaseli efekthri yamaseli ewashwe ngebhafa ye-PBS, indawo yokulahla ingakhishwa, bese kushintshwa indlela entsha ukuze kwande amaseli. inqubo yamasiko efektri. Ngaphezu kwalokho, isixazululo sokugaya kanye nesixazululo sokumisa ukugaya siyadingeka. Imisebenzi esemqoka yalezi zixazululo ukugcina amaseli esesimweni esingcono sokukhula.
PBS buffer is one of the solutions that need to be used in the cell factory culture process. In addition, digestion solution and digestion stop solution are also needed. The main functions of these solutions are to keep cells in a better growth state.
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.
