Kuchinja PCR: FastCycler Thermal Cycler

Mumunda webiology yemamorekuru,ma "thermal cyclers"zvishandiso zvinokosha kune vaongorori nemasayendisiti. Zvinoita basa rakakosha mukuita kwepolymerase chain reaction (PCR), inova hwaro hwekuwedzera DNA, cloning uye genetic analysis dzakasiyana-siyana. Pakati pevazhinji vanopisa vari pamusika, FastCycler inoonekwa seyakanyanya kunaka nemabasa ayo epamusoro uye zvikamu zvemhando yepamusoro, ichiva muenzaniso wekuvandudza uye kushanda zvakanaka.

Chinonyanya kukosha paFastCycler ndechekuzvipira kwayo kune mhando yepamusoro, ichishandisa zvinhu zvePeltier zvepamusoro kubva kuMarlow, USA. Zvinhu izvi zvinozivikanwa nekuvimbika uye kushanda kwazvo, zvichiita kuti FastCycler iwane mwero wekupisa unoshamisa unosvika 6°C/S. Kugona uku kukurumidza kumhanya kwakakosha pakuderedza nguva yese inodiwa paPCR cycling, zvichibvumira vaongorori kuwana mhedzisiro nekukurumidza pasina kukanganisa kuvimbika kwekuyedza.

Chimwe chezvinhu zvinoshamisa zveFastCycler ndechekuti inotenderera zvinhu zvinoshamisa, inodarika mamiriyoni zana emasekonzi. Kugara kwenguva refu uku kunoreva kuti vaongorori vanogona kushandisa FastCycler kwenguva yakareba, zvichiita kuti ive mari inodhura zvishoma kuma laboratories anoda nguva dzose uye kudzokorora kupisa. Kugara kwenguva refu kweFastCycler kunoratidza dhizaini yayo yakasimba uye mainjiniya, ichiva nechokwadi chekuti inogona kutsungirira kuomarara kwekushandiswa kwemasekonzi zuva nezuva.

Kururama kwekupisa kwakakosha mukushandiswa kwePCR, uye FastCycler inobudirira panyaya iyi. Nehunyanzvi hwepamusoro hwekupisa nekutonhodza hwethermoelectric pamwe chete nePID (proportional-integral-derivative) tembiricha yekudzora, FastCycler inochengetedza mwero wepamusoro wekururama kwekupisa mukati menguva yese yekufamba nebhasikoro. Kururama uku kwakakosha pakuwana kuwedzera kwakakwana kweDNA, sezvo kunyangwe kutsauka kudiki mukupisa kunogona kutungamira kumhedzisiro yakaipa kana kutadza kwekuyedza.

Kufanana mumatsime ese chimwe chinhu chakakosha pakutenderera kwekupisa, uye FastCycler hainyadzisi. Dhizaini yayo inoita kuti sampuli dzese dzipiswe uye dzitonhodzwe nguva dzose, izvo zvakakosha pakuedza kunoda mamiriro akafanana. Kufanana uku kunoderedza kusiyana kwemhedzisiro, zvichipa vaongorori chivimbo chekuti data ravo rakavimbika uye rinogona kudzokororwa.

Pamusoro pezvo, FastCycler inoshanda neruzha rwakaderera, zvichiita kuti ive yakakodzera nzvimbo dzemurabhoritari dzinoda nzvimbo yakanyarara. Iyi nzira haingogadzirisi chete mamiriro ekushanda evaongorori, asiwo inoita kuti ruzivo rwemurabhoritari ruve rwakananga uye runoshanda.

Muchidimbu,FastCycler Thermal Cyclerinomiririra kufambira mberi kukuru mu tekinoroji yePCR. Nezvinhu zvayo zvePeltier zvemhando yepamusoro, kumhanya kwekukurumidza, chiyero chakanaka chekufamba nebhasikoro, uye nzira yepamusoro yekudzora kupisa, yakagadzirirwa kusangana nezvinodiwa netsvakiridzo yemazuva ano yemakemikari ebhayoloji. Kunyangwe uri kuita ongororo yeDNA kana kuita tsvakurudzo yakaoma yemajini, FastCycler inopa kushanda kwepamusoro, kuvimbika, uye kushanda zvakanaka. Kudyara muFastCycler zvinoreva kuisa mari mune ramangwana retsvakiridzo yako, kuve nechokwadi chekuti une maturusi aunoda kuti upfuure miganhu yekutsvaga kwesainzi.
