Urunigi rwa polymerase (PCR) rwahinduye ibinyabuzima bya molekuline, bituma abahanga mu bya siyansi bongera urutonde rwa ADN mu buryo butangaje kandi bunoze. Intandaro yimikorere ni PCR yumuriro wa PCR, igikoresho gikomeye kigenzura ukwezi kwubushyuhe bukenewe kugirango ADN itandukane, annealing, no kwaguka. Nyamara, imikorere ya PCR yumuriro wa PCR biterwa cyane na kalibrasi yayo. Iyi ngingo irasobanura akamaro ka PCR yumuriro wa cycler ya kalibrasi ningaruka zayo mubisubizo byubushakashatsi.
Ihinduka rya aUmukinnyi wa PCRiremeza ko igikoresho gikora mubipimo byubushyuhe bwagenwe kandi bikagumana ibisobanuro bikenewe kugirango amplifisione igerweho. Kugenzura ubushyuhe nibyingenzi muri PCR kuko buri ntambwe yumuzingi ishingiye kumiterere yubushyuhe nyabwo. Kurugero, mugihe cyo gutandukana, imirongo ya ADN igomba gushyuha kugeza kuri 94-98 ° C kugirango ubatandukanye. Niba ubushyuhe buri hasi cyane, gutandukana kutuzuye bishobora kubaho, bikavamo amplification idakora neza. Ibinyuranye, niba ubushyuhe buri hejuru cyane, burashobora kwangiza ADN cyangwa enzymes zikoreshwa mubitekerezo.
Byongeye kandi, intambwe ya annealing isaba ubushyuhe bwihariye, ubusanzwe bugenwa nubushyuhe bwo gushonga bwa primers yakoreshejwe. Niba ubushyuhe bwumuriro butagabanijwe neza, ubushyuhe bwa annealing burashobora kuzimya, bikaviramo guhuza bidafite akamaro cyangwa kubura burundu. Ibi birashobora kuvamo umusaruro muke cyangwa kongera ibicuruzwa bitateganijwe, amaherezo bikabangamira ubusugire bwubushakashatsi.
Guhinduranya bisanzwe bya PCR yubushyuhe bwa PCR ningirakamaro kugirango ukomeze ibisubizo byizewe kandi byororoka. Igihe kirenze, abatwara amagare yumuriro barashobora kuva mumiterere yabo ya kalibrasi bitewe nimpamvu nko kwambara no kurira, ihinduka ryibidukikije, ndetse n’imihindagurikire y’amashanyarazi. Igenzura risanzwe rishobora gufasha kumenya itandukaniro no kwemeza ko igikoresho gikora neza. Ibi ni ingenzi cyane mubidukikije byubushakashatsi aho ibipimo nyabyo ari ingenzi, nko mubisuzumisha kwa kliniki, ubushakashatsi bwerekeranye na geneti, hamwe nisesengura ryubucamanza.
Usibye kwemeza neza ubushyuhe bwubushyuhe, kalibrasi igira uruhare runini mumikorere rusange ya PCR yumuriro wa PCR. Imashini ihinduwe neza irashobora kongera imikorere yimikorere ya PCR, bityo ikongera umusaruro wa ADN igamije. Ibi ni ingenzi cyane mubikorwa bifite ibikoresho bike byo gutangira, nk'isesengura rimwe cyangwa ubushakashatsi bwa ADN bwa kera. Mugukoresha neza imikorere ya amplification, abashakashatsi barashobora kubona ADN ihagije ya progaramu yo hasi, nko gukurikiranya cyangwa gukoroniza.
Byongeye kandi, akamaro ka kalibrasi ntikarenze igeragezwa rimwe. Mu bidukikije bigengwa na laboratoire, ingamba zikomeye zo kugenzura ubuziranenge zigomba kubahirizwa. Guhinduranya bisanzwe bya PCR yubushyuhe bwamashanyarazi nibisabwa kugirango hubahirizwe ibipimo ngenderwaho. Kunanirwa gukomeza kalibrasi ikwiye birashobora gutuma habaho ibisubizo bidahwitse, bishobora kugira ingaruka zikomeye kubuvuzi no gufata ibyemezo byo kuvura.
Mu gusoza, kalibrasi yaAmagare ya PCRni ikintu cyibanze cyibinyabuzima bya molekuline bidashobora kwirengagizwa. Kugenzura ubushyuhe nyabwo ni ingenzi cyane kugirango PCR igerweho, kandi kalibrasi isanzwe yemeza ko icyuma cyumuriro gikora mubisabwa bikenewe. Mugushira mubikorwa kalibrasi, abashakashatsi barashobora kunoza kwizerwa no kubyara ibisubizo byabo, amaherezo bateza imbere urwego rwibinyabuzima bya molekuline nuburyo bukoreshwa mubuvuzi, genetiki, nibindi byinshi. Mugihe icyifuzo cya tekiniki zuzuye kandi zuzuye zikomeje kwiyongera, akamaro ko gukomeza kalibari nziza ya PCR yumuriro wumuriro bizagenda bigaragara cyane.
