Ultra Nuclease GMP-ibakala
Inombolo yekati: HC2016A
I-UltraNuclease GMP-grade ichazwa kwaye ihlanjululwe kwi-Escherichia coli (E.coli) nge-genetically engineered kwaye ilungiswe phantsi kweemeko ze-GMP.Inokunciphisa i-viscosity ye-cell supernatant kunye ne-cell lysate kuphando lwezenzululwazi, ukwandisa ukusebenza kweprotheyini yokucoca kunye nokuphucula uphando olusebenzayo lweprotheni.Imveliso inokunciphisa iintsalela ze-nucleic acid ezihlala kwi-pg-grade, ukuphucula ukusebenza kunye nokhuseleko lweemveliso zebhayoloji zezicelo ezibandakanya ukucocwa kwentsholongwane, ukuveliswa kwesitofu sokugonya, kunye neprotheyini / i-polysaccharide yokuvelisa amayeza.Ngaphandle koko, imveliso ingasetyenziselwa ukuthintela ukudityaniswa kweeseli zegazi ze-mononuclear zegazi (PBMC) kunyango lweeseli kunye nophuhliso lwesitofu.
I-UltraNuclease inikwe ngohlobo lwe-reagent entsholongwane, eluted kwi-buffer (20mM Tris-HCL pH 8.0, 2mM MgCl, 20 mM NaCl, 50% glycerin), kunye nenkangeleko yolwelo olungenambala, olucacileyo.Le mveliso iveliswa ngokweemfuno zenkqubo ye-GMP kwaye inikezelwe ngendlela engamanzi.
Amacandelo
I-UltraNuclease GMP-grade (250 U/μL)
Iimeko zokuGcina
Imveliso ithunyelwa ngeqhwa elomileyo kwaye ingagcinwa kwi -25 ℃ ~ -15 ° C iminyaka emibini.
Ukuba imveliso ivuliwe kwaye igcinwe kwi-4℃ ngaphezu kweveki, sincoma ukuhluzaimveliso yokuthintela ungcoliseko lwe-microbial.

Imiyalelo
1. Isampuli Ingqokelela
Iiseli ezibambelelayo: susa okuphakathi, hlamba iiseli nge-PBS, kwaye ususe i-supernatant.
Iiseli ezimisiweyo: qokelela iiseli nge-centrifugation, hlamba iiseli nge-PBS, i-centrifuge kwi-6,000rpm i-10 min, qokelela i-pellet.
I-Escherichia coli: qokelela iibhaktheriya nge-centrifugation, hlamba kube kanye nge-PBS, i-centrifuge kwi-8,000rpm i-5 min, kwaye uqokelele i-pellet.
2. Unyango lweSampuli
Phatha iipellets zeseli eziqokelelweyo nge-lysis buffer kumlinganiselo wobunzima (g) ukuya kumthamo(mL)1:(10-20), okanye ngeendlela zoomatshini okanye zekhemikhali kumkhenkce okanye kubushushu begumbi (1g yepellet yeseli iqulathe malunga
Iiseli ezili-109).
3. Unyango lwe-Enzyme
Yongeza i-1-5mM MgCl kwinkqubo yokuphendula kwaye ulungelelanise i-pH kwi-8-9.
Yongeza i-UltraNuclease ngokomlinganiselo weeYunithi ezingama-250 ukwetyisa i-1 g yeepellets zeseli, zifukame ku-37℃ ngaphezu kwemizuzu engama-30.Nceda ujonge kwifomu ethi “Ixesha Lokuphendula eliCetyisiweyo” ukukhetha iixesha lonyango.
4. Onamandla Ingqokelela
I-Centrifuge kwi-12,000 rpm imizuzu engama-30 kwaye uqokelele i-supernatant.
Qaphela: Ukuba isisombululo sineasidi okanye i-alkaline, okanye iqulethe ityuwa eninzi, izinto zokucoca, okanyedenaturants, nceda wandise umthamo we-enzyme okanye wandise ixesha lonyango ngokufanelekileyo.
