Ikhithi Yokuthola i-Shigella PCR

Incazelo emfushane:

I-Shigella iwuhlobo lwe-gram-negative brevis bacilli, eyingxenye yamagciwane asemathunjini, kanye ne-pathogen evame kakhulu ye-human bacillary dysentery.

Ukusetshenziswa Okuhlosiwe

I-Shigella iwuhlobo lwe-gram-negative brevis bacilli, eyingxenye yamagciwane asemathunjini, kanye ne-pathogen evame kakhulu ye-human bacillary dysentery.Le khithi isebenzisa umgomo we-PCR wesikhathi sangempela we-fluorescent, ofanele ukunqunywa kwe-Shigella ekudleni, amasampula amanzi, indle, ukuhlanza, noketshezi lokunothisa.

Okuqukethwe Komkhiqizo

Izingxenye Iphakheji ukucaciswa Isithako
I-PCR Mix 1 × ibhodlela (Lyophilized powder)  50Isivivinyo dNTPs, MgCl2, Iziqalisi, Ama-Probes, i-Taq DNA polymerase
I-6 × 0.2ml 8 ithubhu ye-strip kahle(I-Lyophilized) 48Isivivinyo
Ukulawula Okuhle 1 * 0.2ml ishubhu (lyophilized)  10Izivivinyo

I-Pseudovirus noma i-Pseudovirus equkethe izingcezu ezithile

Isixazululo sokuqedwa 1.5 ml Cryotube 500uL /
Ukulawula Okungalungile 1.5 ml Cryotube 100uL 0.9%NaCl

Isitoreji Nempilo Yeshelufu

(1)Ikhithi ingathuthwa ngezinga lokushisa elilingana negumbi.

(2) Impilo yeshelufu yizinyanga eziyi-18 ku -20 ℃ kanye nezinyanga eziyi-12 ku-2 ℃ ~ 30 ℃.

(3)Bona ilebula kukhithi yedethi yokukhiqiza kanye nosuku lokuphelelwa yisikhathi.

(4)I-lyophilized powder version reagent kufanele igcinwe ku--20 ℃ ngemva kokuchithwa kanye nokuqhwaza okuphindaphindiwe -kuncibilika kufanele kube izikhathi ezingaphansi kwezi-4.

Izinsimbi

I-GENECHECKER UF-150, ithuluzi le-PCR le-UF-300 lesikhathi sangempela se-fluorescence.

*Uma umphumela wokuhlolwa kabusha wesiteshi se-FAM unenani elingu-Ct ≤40 futhi ubonisa ijika lokukhulisa umumo elithi “S” elivamile, umphumela uhunyushwa njengophozithivu, ngaphandle kwalokho uthi unegethivu.
