Ukuthuthukiswa kobuchwepheshe be-cell culture sekuvuthwe kakhulu kuze kube manje. Ukukhula kweseli kudinga ukuhlangabezana nezidingo ezihlukahlukene ezifana nemvelo, izinga lokushisa, ukucindezela kwe-osmotic, inani le-pH, njll. Ngaphezu kokuhlinzeka ngemisoco eyisisekelo emithonjeni ehlukahlukene yokwenziwa, kuyadingeka futhi ukuzivumelanisa namaseli ahlukene nezinjongo zamasiko ahlukene. Engeza i-serum nezinye izinto ukukhuthaza ukukhula kwamaseli. Ngakho-ke, i-media bottles inezinhlobonhlobo zezinhlelo zokusebenza emkhakheni we-cell culture.
I-Serum iyingxube eyinkimbinkimbi kakhulu eyakhiwe ngokukhipha i-fibrinogen ku-plasma, ikakhulukazi okuhlanganisa i-fetus serum, i-calf serum, inkomo yabantu abadala. i-serum, i-serum yamahhashi, i-serum yembuzi, i-serum yenkukhu, i-rabbit serum, njll, phakathi kwayo i-fetal bovine serum isetshenziswa. isetshenziswa kakhulu. ISerum ihlinzeka ngezinto ezibalulekile ezifana ne-extracellular matrix, izici zokukhula kanye ne-transferrin. Ingxenye ye-serum eyengeziwe kufanele inqunywe ngokuya ngamaseli ahlukene kanye nezinjongo ezihlukene zocwaningo. I-10% ~ 20% i-serum ingagcina ukukhula okusheshayo kanye nezinga lokusabalala kwamaseli, okubizwa ngokuthi ukukhula okuphakathi; ukuze kugcinwe ukukhula okuhamba kancane noma ukungafi kwamangqamuzana, kungase kwengezwe i-serum engu-2% ~5%, ebizwa ngokuthi i-maintenance medium. C. Amabhodlela emidiya ngokuvamile enziwa ngezinto ze-PET ezisobala ngobuchwepheshe bokuvuthela ngomjovo. Le nto inokumelana nokuguga okuhle kokushisa, izinga lokushisa le-embrittlement elingu--70 °C, futhi isenokuqina okuthile ku--30 °C, okuhlangabezana nezidingo zokugcina ze-serum. . Futhi ibhodlela lemidiya lizokwenziwa inzalo, alikho i-pyrogen, alikho i-endotoxin, alikho i-DNase, alikho i-RNase nezinye izici ezithinta ukukhula kwamangqamuzana.
I-Serum iyinto ebalulekile yesiko lamaseli. Ngokuthuthuka okuqhubekayo kwemikhiqizo yebhayoloji, i-immunotherapy, izikhungo zocwaningo lwesayensi neminye imikhakha, isidingo se-serum sizokhula, futhi ibhodlela lemidiya lizoba nokusetshenziswa okubanzi emkhakheni wesiko lamaseli.
Serum is an indispensable item for cell culture. With the continuous development of biological products, immunotherapy, scientific research institutes and other fields, the demand for serum will also increase, and the media bottle will also have a wider application in the field of cell culture.
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.
