Xav txog hom kev sim uas koj yuav ua. Koj puas siv tus qauv PCR, tus lej PCR (qPCR), lossis daim ntawv thov high-throughput? Txhua daim ntawv thov no yuav xav tau cov yam ntxwv thiab peev xwm sib txawv ntawm lub thermal cycler.

2. Qhov Kub thiab Kev Sib Xws

Qhov kub ntawm lub tshuab cua sov yog ib qho tseem ceeb heev. Feem ntau cov txheej txheem PCR xav tau kauj ruam denaturation ntawm kwv yees li 94-98 ° C, kauj ruam annealing ntawm 50-65 ° C, thiab kauj ruam txuas ntxiv ntawm 72 ° C. Xyuas kom tseeb tias lub tshuab cua sov uas koj xaiv tuaj yeem tswj tau cov kub no thiab qhov kub tau faib sib npaug thoob plaws hauv lub module. Qhov kub tsis sib xws tuaj yeem cuam tshuam rau koj txoj kev tshawb fawb los ntawm kev ua rau cov txiaj ntsig tsis sib xws.

3. Hom ntawv thaiv thiab peev xwm

Cov khoom siv cua sov muaj ntau hom modular, suav nrog 96-qhov phaj, 384-qhov phaj, thiab txawm tias 1536-qhov phaj. Kev xaiv hom block yuav tsum phim koj cov kev xav tau throughput. Yog tias koj ua qhov kev sim siab-throughput, koj yuav xav tau hom block loj dua. Ntawm qhov tod tes, rau cov kev sim me me, 96-qhov phaj yuav txaus. Tsis tas li ntawd, xav txog seb koj puas xav tau cov modules sib pauv tau hauv ntau hom ntawv, vim qhov no tuaj yeem ua rau koj txoj kev tshawb fawb ntau dua.

4. Kev Ceev thiab Kev Ua Haujlwm Zoo

Nyob rau hauv qhov chaw tshawb fawb niaj hnub no uas nrawm heev, lub sijhawm yog qhov tseem ceeb. Nrhiav lub tshuab cua sov uas muaj peev xwm ua kom sov thiab txias sai. Qee cov qauv siab heev tuaj yeem ua tiav lub voj voog PCR hauv qab 30 feeb, ua kom koj txoj haujlwm ua haujlwm sai dua. Tsis tas li ntawd, cov yam ntxwv xws li hom ceev lossis cov nqi cua sov sai ua rau muaj kev ua haujlwm zoo dua, cia koj ua cov qauv ntau dua hauv lub sijhawm tsawg dua.

5. Tus Neeg Siv Interface thiab Software

Ib qho interface uas yooj yim siv yog qhov tseem ceeb rau kev ua haujlwm zoo. Nrhiav lub thermal cycler uas muaj lub vijtsam kov tau yooj yim, cov kev xaiv programming yooj yim, thiab cov txheej txheem preset. Cov qauv siab heev kuj tseem tuaj yeem nrog software uas tso cai rau kev saib xyuas lub sijhawm tiag tiag thiab kev tshuaj xyuas cov ntaub ntawv, uas yog qhov tshwj xeeb tshaj yog rau cov ntawv thov qPCR. Xyuas kom tseeb tias software sib xws nrog koj cov kab ke uas twb muaj lawm thiab tuaj yeem tswj cov ntaub ntawv tso tawm uas koj xav tau.

6. Kev Xav Txog Nyiaj Txiag

Cov tshuab cua sov sib txawv ntawm tus nqi, yog li nws tseem ceeb heev kom muaj peev nyiaj ua ntej koj pib yuav ib qho. Txawm hais tias nws yuav ua rau koj xav xaiv qhov pheej yig tshaj plaws, xav txog qhov txiaj ntsig mus sij hawm ntev ntawm kev nqis peev rau hauv lub tshuab zoo uas ua tau raws li koj cov kev xav tau tshawb fawb. Xav txog tsis yog tus nqi yuav thawj zaug xwb, tab sis kuj tseem xav txog tus nqi ntawm cov khoom siv, kev saib xyuas, thiab kev txhim kho tshiab.

7. Kev Txhawb Nqa thiab Kev Lav Paub ntawm Chaw Tsim Khoom

Thaum kawg, xav txog qib kev txhawb nqa thiab kev lees paub uas lub chaw tsim khoom muab. Lub tshuab cua sov uas ntseeg tau yuav tsum muab kev lees paub tag nrho thiab muaj kev pabcuam rau cov neeg siv khoom rau kev daws teeb meem thiab kev saib xyuas. Qhov no txuag koj lub sijhawm thiab cov peev txheej hauv lub sijhawm ntev.
