Njengenye yezinto ezisetshenziswa kakhulu kusikompilo lwamaseli, amaflasks e-cell culture idlala indima ebalulekile ekukhuleni nasekukhiqizeni kabusha amaseli. Njengamanje, amabhodlela e-cell culture emakethe ikakhulukazi enziwe ngengilazi noma izinto zepulasitiki. Lolu hlobo lwezinto ezisetshenziswayo luhlukile kumabhodlela epulasitiki ezokwelapha ajwayelekile, futhi intengo iphakeme uma kuqhathaniswa. Ingabe lolu hlobo lwamabhodlela lungasetshenziswa kabusha?
Uma usebenzisa iflaski yamaseli engilazi, ungakwazi ukucwiliswa emanzini ahlanzekile imizuzu engaphezu kwengu-30, wengeze into encane yokuhlanza, ugeze nge-ultrasonic isikhathi esingaphezu kwalokho. Imizuzu engu-30, khipha futhi wome, bese ucwilisa ku-chromic acid lotion amahora angu-6-18, bese uhlanza ngamanzi kampompi izikhathi ezingu-10-15, hlambulula ngamanzi acwecwe kabili izikhathi ezingu-3-4, womile, futhi u-autoclave ngaphambi kokusebenzisa futhi.
Iningi lamaflask amanje amasiko eseli enziwe ngezinto zepulasitiki, futhi eziningi zazo ziyakwazi ukulahlwa futhi zingadlula izizukulwane ezimbalwa zamaseli kakhulu. Kodwa amangqamuzana azwela kakhulu endaweni ezungezile. Uma ziphinde zisetshenziswe izikhathi eziningi, izinto ezikhiqizwe ukukhula kwamangqamuzana nezinto ezisele zamaseli afile zizohlala ebhodleleni futhi kuthinte ukukhula kwamaseli amasha. Ngaphezu kwalokho, ama-flasks e-cell culture anezici ezikhuthaza ukunamathela kwamangqamuzana nokukhula. Ngezingxenye eziningi, lezi zici zizokhula kancane. Ngakho-ke, kuncike esimweni sokukhula kweseli. Ngokuvamile, izizukulwane ezingu-2-3 zilungile. 3 Kunconywa ukuthi kushintshwe isizukulwane.
Kukonke, ukuze ukhule kahle, amaflask e-cell culture akunconywa ukuthi usetshenziswe kabusha. Uma kuqhathaniswa ne-culture medium kanye ne-serum esetshenziselwa ukulima amaseli, izindleko zezinto ezidliwayo akufanele zishiwo. Yiqiniso, ukuthi amangqamuzana angakwazi ukuzala ngokuvamile akuxhomekile kuphela kumabhodlela amasha namadala amaseli, kodwa nokuthi uyanaka yini ukusebenza kwe-aseptic. Uma inqubo yokusebenza ingalungile, ngisho namabhodlela angcono kakhulu azophazamisa ukukhula kwamaseli.
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.
