Koyi game da Mini PCR: Kayan aiki na juyin juya hali don ilimin halitta

Tun lokacin da aka fara shi a cikin 1980s, tsarin sarkar polymerase (PCR) ya canza fasalin ilimin kwayoyin halitta. Wannan dabarar tana ba masana kimiyya damar haɓaka takamaiman sassan DNA, yana ba da damar yin cikakken bincike akan abubuwan halitta. Daga cikin ci gaba daban-daban a fasahar PCR, mini-PCR ta fito a matsayin madaidaiciya kuma ingantaccen madadin da zai iya saduwa da aikace-aikace da yawa a cikin bincike, bincike, da ilimi.

Menene Mini PCR?

Karamin injunan PCR, galibi ana kiransa mini masu hawan keke, ƙanana ne, nau'ikan injunan PCR na gargajiya. An ƙera waɗannan na'urori don yin aiki na asali iri ɗaya kamar manyan injunan PCR: haɓaka DNA. Koyaya, ƙananan injunan PCR an inganta su don ƙananan samfuran samfura, yawanci tsakanin 5 zuwa 20 microliters, yana mai da su manufa don aikace-aikace tare da iyakataccen adadin DNA.
