1.Imwe-nhanho qRT-PCR.
2.Kuonekwa kwehutachiona hweRNA.
Storage Condition
-20°C kuitira kuchengetedza kwenguva refu, inofanira kusanganiswa zvakanaka isati yashandiswa, dzivisa kugaro chando-nyorova.
Chikamu Tsanangudzo
Chimwe chikamu chinosanganisa 1 nmol yedTTP mumaminetsi gumi pa37°C uchishandisa poly(A)•oligo(dT)25se template/primer.
Quality Control
1.SDS-PAGE electrophoretic kuchena kukuru kupfuura 98%.
2.Amplification senitivity, batch-to-batch control, kugadzikana.
3.Hapana exogenous nuclease chiitiko, hapana exogenous endonuclease kana exonuclease kusvibiswa.
Reaction Setup yeFirst Chain Reaction Solution
1.Kugadzirira kwemusanganiswa wekuita
Zvikamu | Volume |
Oligo(dT)12-18 Primer kana Random Primera Kana Gene Specific Primersb | 50 pmol |
50 pmol (20-100 pmol) | |
2 pmol | |
10 mM dNTP | 1 μL |
RNA template | Zvose RNA≤ 5μg;mRNA≤ 1 μg |
RNase-isina dH2O | Kusvika ku10 μL |
Notes:a/b: Ndokumbira usarudze mhando dzakasiyana dzemaprimers zvinoenderana nezvido zvako zvekuyedza.
2.Pisa pa65°C kwe5mins uye wotonhorera nekukurumidza paaizi kwema2mins.
3.Wedzera zvinotevera zvikamu kune iri pamusoro system kune yakazara vhoriyamu ye20µL uye sanganisa zvinyoro nyoro:
Zvikamu | Vhoriyamu (μL) |
5 × Kutanga-Strand Buffer | 4 |
Neoscript Reverse Transcriptase (200 U/μL) | 1 |
RNase inhibitor (40 U/μL) | 1 |
RNase-isina dH2O | Kusvika ku20 μL |
4.Ndapota ita mhinduro maererano nemamiriro anotevera:
(1) Kana Random Primer ikashandiswa, maitiro anofanirwa kuitwa pa25 ℃ kwe10mins, uyezve pa50 ℃ ye30 ~ 60mins;
(2) Kana Oligo dT kana chaiyo primers yakashandiswa, maitiro anofanirwa kuitwa pa50 ℃ kwe30 ~ 60mins.
5.Kupisa pa95 ℃ kwe5mins kudzima Neoscript Reverse Transcriptase uye kumisa kuita.
6.Reverse transcription products zvinogona kushandiswa zvakananga muPCR reaction uye fluorescence quantitative PCR reaction, kana kuchengetwa pa -20 ℃ kwenguva yakareba.
PCR Rchiito:
1.Kugadzirira kwemusanganiswa wekuita

Notes:a: Kana yakawandisa yekutanga chain reaction solution yakawedzerwa, PCR reaction inogona kudziviswa.
2.PCR Reaction Procedure
Danho | Tembiricha | Nguva | Cycles |
Pre-denaturation | 95℃ | 2-5 mins | 1 |
Denaturation | 95℃ | 10-20 sec | 30-40 |

Notes
1.Inokodzera reverse transcription tembiricha optimization mumhando ye42 ℃ ~ 55 ℃.
2.Iyo ine kugadzikana kuri nani, yakakodzera kune yakakwira tembiricha reverse transcription amplification.Pamusoro pezvo, yakanakira kupfuura nemumatunhu akaoma eRNA.Uyezve, izvozvoinokodzera nhanho imwe-multiplex fluorescence quantitative RT-PCR yekuona.
3.Kuenderana kwakanaka neakasiyana PCR amplification enzymes uye inokodzera yakakwira senitivity RT-PCR maitiro.
4.Inokodzera yakakwirira senitivity imwe-nhanho fluorescence kuwanda RT-PCR maitiro, zvinobudirira kuvandudza mwero wekuona wekushomeka kwematemplate.
5.Inokodzera cDNA raibhurari kuvaka.
