Ni gute wamenya urugero rwiza rw'ibinure?
Ku inducer IPTG (isopropyl-beta-d-thiogalactoside), uko industry iba nyinshi niko iba nziza kurushaho. Industry nziza iterwa n'imiterere yihariye y'igerageza n'ingaruka nziza z'industry.
Muri rusange, ingano ya IPTG ikoreshwa hagati ya 0.1-1 mM. Ingano nke ishobora kugabanya ingaruka mbi ku mikurire y'uturemangingo kandi ikagabanya uburozi buterwa no kwiyongera cyane kwa poroteyine. Ingano nyinshi ishobora gutera umutwaro ukabije w'imikorere y'uturemangingo, bigatera ingaruka ku mikurire y'uturemangingo no ku mikorere myiza yatwo.
Uburyo bwo kumenya urugero rwiza rushobora kuba ugusuzuma urugero rw'igaragara rya poroteyine y'intego hakoreshejwe ibizamini bya IPTG ku bipimo bitandukanye. Ibizamini bito byo gupima bishobora gukorwa hakoreshejwe ibipimo bitandukanye bya IPTG (urugero: 0.1 mM, 0.5 mM, 1 mM, nibindi) kandi ingaruka z'igaragara ku bipimo bitandukanye zishobora gusuzumwa hakoreshejwe kumenya urugero rw'igaragara rya poroteyine y'intego (urugero: Western blot cyangwa fluorescence detection). Dukurikije ibyavuye mu bushakashatsi, urugero rufite ingaruka nziza z'igaragara rwatoranyijwe nk'urugero rwiza.
Byongeye kandi, ushobora kandi kureba inyandiko zijyanye n'ibyo cyangwa ubunararibonye bw'izindi laboratwari kugira ngo wumve urwego rw'ibipimo bya IPTG bikunze gukoreshwa mu bihe bisa byo kugerageza, hanyuma urusheho kunoza no guhindura uko ubyifuza mu igerageza.
Ni ngombwa kumenya ko ingano nziza ishobora gutandukana bitewe n'uburyo butandukanye bwo kugaragaza, poroteyine zigamije, n'imiterere y'igerageza, bityo ni byiza kunoza buri kimwe uko cyakabaye.
