I-Serum inendima engenakuthathelwa indawo ekukhuleni kwamangqamuzana nokwanda kwesiko lamaseli, ngakho-ke i-serum idlala kanjani indima kusikompilo lwamaseli, futhi yiziphi izidingo media bottle ukupakisha?
Function of Serum:
1. Izinto eziyinhloko ku-serum amaprotheni, i-albumin, njll., ezingakhiya i-pH yendawo ye-cell culture futhi igcine umfutho we-osmotic;
2. Amaprotheni abophayo afana ne-transferrin ne-thyroxine-binding protein angabona amavithamini, lipids, izinsimbi namanye amahomoni, njll., futhi angahlangana nezinsimbi ezinobuthi nama-pyrogens ukuze akhiphe ubuthi;
3. I-Fibronectin, i-fetuin kanye nezici zokunamathela ku-fetal bovine serum ingakhuthaza ukunamathela kwamangqamuzana nokusabalala;
4. Ama-polypeptide afana ne-platelet growth factor, i-fibroblast growth factor, i-epidermal growth factor, i-nerve cell growth factor, i-insulin, ukukhula okufana ne-insulin, i-somatotropin, i-hydrocortisone, njll. . Ama-protease inhibitors afana ne-macroglobulin angavimbela i-protease futhi avikele amaseli emonakalweni;
6. I-Serum icebile futhi ngama-amino acid, i-glucose, ama-ketoacids kanye nezakhi zokulandelela kuhlanganiswe namaprotheni, abalulekile empumelelweni yamangqamuzana.
Izimfuneko zamabhodlela emidiya:
I-Serum inezingxenye eziyinkimbinkimbi nemisebenzi ebalulekile, ngakho-ke ukulondolozwa nokusetshenziswa. i-serum ibaluleke kakhulu. Ekukhetheni amabhodlela e-serum, umzimba webhodlela ngokuvamile udingeka ukuthi ube sobala, ungenayo i-DNase, i-RNase, i-pyrogen nezinye izinto ezithinta ukukhula kwamaseli, futhi uvalwe ukuvimbela ukuvuza. Kuyaphawuleka ukuthi i-serum ngokuvamile idinga ukugcinwa endaweni ephakathi kuka -5 °C kuya -20 °C, ngakho-ke impahla yebhodlela lemidiya kufanele futhi ihlangabezane nezici zokumelana nezinga lokushisa eliphansi.
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.
