Waa maxay sababta alaabta PCR guud ahaan looga sameeyay PP?

2023-03-18

"Sida aan wada ognahay, PCR waa habka tijaabada aasaasiga ah ee shaybaarada biochemical." Natiijooyinka tijaabada ah ayaa had iyo jeer ah kuwo aan ku qanacsanayn, taas oo laga yaabo inay sabab u tahay wasakheynta yar ee isticmaalka caagagga PCR, ama faragelinta tijaabada ah ee ay sababtay hor-u-dhigayaasha. Waxaa jirta sabab kale oo aad muhiim u ah: Xulashada aan saxda ahayn ee alaabta la isticmaalo waxay sidoo kale saameyn weyn ku yeelan doontaa natiijooyinka tijaabada ah.

Waxaa jira sababo badan oo saameeya natiijooyinka tijaabooyinka PCR: badanaa waxaa jira 7 nooc oo soo socda.

1. Furayaasha: Furaha ayaa fure u ah falcelinta gaarka ah ee PCR, gaar ahaana badeecadaha PCR waxay kuxirantahay heerka dhammaystirka u dhexeeya aasaasayaasha iyo DNA-ga template;

2. Enzyme iyo fiirsigiisa;

3. Tayada iyo xoojinta dNTP;

4. Template ( hiddo-wadaha bartilmaameedka ) nucleic acid;

5. Mg2+ xoojinta;

6. Dejinta heerkulka iyo waqtiga;

7. Tirada wareegyada;

8. Qalab, agab, iwm.

Waxyaalaha badan ee saamaynta ku leh waxa ka mid ah, alaabtu waa mid ka mid ah qodobbada aadka muhiimka u ah oo si fudud loo ilduufo.

Waxaa jira noocyo badan oo ka mid ahIsticmaalka PCR: 8-tuubyo, tuubooyinka mugga hoose, tuubooyinka caadiga ah, kuwa aan dharka lahayn,-kabi-dhismeed, dhar buuxa, iyo taxane PCR iyo qPCR ah. Aad bay u adag tahay in la doorto, waxaana jira dhibaatooyin badan oo caadi ah, aan eegno dhibaatooyinka uu qof kastaa doortoIsticmaalka PCR, iyo sida loo xalliyo?

Waa maxay sababtaIsticmaalka PCRguud ahaan laga sameeyay PP?

Jawaab: Isticmaalka PCR/qPCR guud ahaan waxay ka samaysan yihiin polypropylene (PP), sababtoo ah waa walxo bayooloji ah oo aan firfircoonayn, dusha sare ma fududa in lagu dhejiyo biomolecules, waxayna leedahay caabbinta kiimikada wanaagsan iyo dulqaad heerkulka (waxaa lagu dhejin karaa 121 digrii) bakteeriyada iyo sidoo kale u adkeysan kara isbeddelada heerkulka inta lagu jiro baaskiil kulaylka). Qalabkani inta badan waxay si toos ah ula xiriiraan reagents ama shaybaarrada, markaa agab tayo sare leh iyo farsamooyinka habaynta wanaagsan ayaa loo baahan yahay in la doorto inta lagu jiro habka wax soo saarka iyo diyaarinta.
