Ibali malunga neeseli zethu: Masifunde ngovavanyo lweFlow Cytometry ngendlela elula!

Ngaba wakha weva ngovavanyo olubizwa ngokuba yiFlow Cytometry? Mhlawumbi ugqirha wakho ukuxelele ngolu vavanyo. Okanye mhlawumbi lutsha kuwe. Nangona kunjalo, luvavanyo olubaluleke kakhulu olusinceda sifumane ulwazi oluninzi malunga neeseli emzimbeni wethu. Namhlanje, siza kuthetha ngalo ngendlela elula onokuyiqonda.

Yintoni iFlow Cytometry?

Ngamafutshane, i-flow cytometry luvavanyo lwelebhu olusetyenziselwa ukufumana iinkcukacha malunga neeseli okanye amasuntswana amancinci emizimbeni yethu. Cinga ngayo njengomphenyi omncinci ojonga ngaphakathi kwiiseli zethu.

Ukuze wenze oku, kuqala isampuli yeeseli zakho (ezinokuba ligazi, umongo wethambo, okanye ezinye izicwili) iyanyibilika kulwelo. Emva koko, ingcali yelabhoratri yongeza iidayi ezikhethekileyo ze-fluorescent antibody kwiiseli. Ezi dayi ziyazibona kwaye zincamathele kwiiproteni ezithile ngaphakathi okanye ngaphakathi kweeseli. Ngamanye amazwi, zincamathisela ilebheli encinci, okanye 'ithegi,' kwezo proteni. Le nkqubo ngamanye amaxesha ibizwa ngokuba yiFluorescence-Activated Cell Sorting (FACS) .

Ezi seli zilungisiweyo emva koko zifakwa kumatshini obizwa ngokuba yi-flow cytometer. Into emangalisayo kukuba, ikhompyutha eqhagamshelwe kulo matshini inokuhlaziya malunga neeseli ezili-10,000 ngomzuzu nje omnye! Ayikhawulezi kangako loo nto?

Ngoko ke, olu vavanyo lusetyenziselwa ntoni?

Oogqirha basebenzisa olu vavanyo lwe-flow cytometry kwizinto ezininzi. Ngokuyintloko:

• Ukubalwa kweeseli: Fumanisa ukuba zingaphi iiseli ezikwisampulu.
• Ukuhlelwa kweeseli: Yahlula kwaye uchonge iintlobo ezahlukeneyo zeeseli.
• Ukuchonga iimpawu kunye nomsebenzi weseli: Fumanisa izinto ezifana nokuma kweseli kunye nendlela esebenza ngayo.
• Ukuxilongwa kunye nonyango lomhlaza wegazi kunye nomongo wamathambo: Oku kubaluleke kakhulu ekuchongeni izifo ezifana ne-leukemia kunye ne-lymphoma.
• Ukufumana ii-biomarkers: Ezi zizinto ezinokuqikelela indlela umhlaza oza kuziphatha ngayo kunye nendlela oza kusabela ngayo kunyango.
• Ukuchonga ii-immunophenotyping: Ukwahlulahlula nokuchonga ukuba zeziphi iintlobo ezahlukeneyo zeeseli zomzimba ezikwimizimba yethu.

Luqhutywa nini uvavanyo lwe-flow cytometry?

Oogqirha basebenzisa olu vavanyo ukuze bafumane ulwazi olunzulu malunga neeseli ezingaphakathi emizimbeni yethu. Ngokukodwa:

• Funda ngeeseli zenkqubo yomzimba yokuzikhusela: Jonga ukuba zingaphi iiseli ezilwa nezifo emizimbeni yethu kwaye zeziphi iintlobo zazo.
• Chonga iiseli zomhlaza kwaye uqonde uhlobo lwazo: Fumanisa indlela iiseli zomhlaza ezahluke ngayo kwezinye iiseli kunye neempawu zazo.
• Phanda ngeemeko zonyango ezintsonkothileyo:
• Umhlaza wegazi: Umzekelo, izifo ezifana ne-leukemia kunye ne-lymphoma.
• Ezinye iingxaki zegazi: Umzekelo, iimeko ezifana ne-paroxysmal nocturnal hemoglobinuria (PNH) kunye nokungabikho kwe-antithrombin.
• Umsebenzi womzimba: Jonga izifo ezifana ne-AIDS (HIV) kunye nokusilela komzimba okuzuzwe njengelifa.

Enye into kukuba, ngamanye amaxesha emva kokuba ugqibe ukubala igazi lakho elipheleleyo (i-CBC) , ukuba kufuneka ulwazi oluthe kratya ngokusekelwe kwiziphumo, olu vavanyo lwe-flow cytometry lunokwenziwa. Ngokukodwa, ukuba i-CBC ibonisa ukwanda kohlobo lweseli olubizwa ngokuba yi-lymphocytes, ukuba kukho ukungaqheleki kwezinye izibalo zeseli, okanye ukuba ibonisa ukubakho kweeseli zegazi ezingavuthwanga, olu vavanyo lunokuyalelwa.

Olu vavanyo lubaluleke kakhulu kungekuphela nje ekuxilongeni umhlaza, kodwa nasekunyangeni umhlaza. Oko kukuthi:

• Khawucinge ukuba umhlaza unamandla kangakanani.
• Qinisekisa ukuba umhlaza uza kuphendula na kunyango oluthile .
• Oku kunceda ekuqinisekiseni ukuba umhlaza uphinde wabuya na emva konyango.

Isebenza njani le flow cytometry machine? Iyamangalisa!

Lo matshini we-flow cytometry uhlalutya iipropati zomzimba nezekhemikhali zeeseli ngokukhawuleza kakhulu. Cinga ngayo njengokujonga iiseli ngekhamera ekhawulezayo kakhulu. Nantsi indlela esebenza ngayo:

1. Ukulungiselela isampuli: Okokuqala, ingcali yelabhoratri ithatha isampuli yegazi lakho, izicubu, okanye umongo wethambo ize iyinyibilikise kulwelo (olubizwa ngokuba yi -'suspension' ). Emva koko, njengoko bekutshiwo ngaphambili, kongezwa idayi ekhethekileyo ebizwa ngokuba yi -'fluorescently tag antibodies' kwiiseli. Isisombululo seseli esilungisiweyo emva koko sifakwa kwi-flow cytometer.

2. Ulungelelwaniso lweeseli kunye nomqadi welaser: Ngaphakathi kumatshini, ezi seli zicwangciswe kumqolo omnye, omnye emva komnye. Khawuthelekelele, njengabantwana besikolo bebekwe kumqolo. Emva koko, olu luhlu lweeseli ludlula phambi komqadi welaser, nganye nganye. Xa umqadi welaser ufika kwiiseli, ukukhanya kuyasasazeka, oko kukuthi, ukukhanya okusasazekileyo.

3. Ukubala nokwahlulahlula iiseli: I-flow cytometer ibala iiseli kwaye izihlela ngendlela umqadi welaser osasaza ngayo ukukhanya xa ufika kwiiseli. Uhlobo ngalunye lweseli lusasaza ukukhanya ngokwahlukileyo. Umatshini wenza oku ngokufumanisa loo mahluko.

4.Idatha kwikhompyutha: Lonke ulwazi (idatha) oluqokelelwe ngumatshini ngale ndlela luthunyelwa kwikhompyutha eqhagamshelwe kuyo.

5. Ukuveliswa kweengxelo: Ikhompyutha ihlalutya olu lwazi ize yenze ingxelo, ngesiqhelo ikwimo yegrafu yamachaphaza okanye yebha .

6. Uhlalutyo lwengcali yezifo: Okokugqibela, ingcali yezifo – ingcali yezonyango exilonga izifo – ihlola ezi grafu kunye nedatha ize yongeze uxwebhu oluqulethe iziphumo kunye nezigqibo zayo kwingxelo yovavanyo.

Ndingenza ntoni ngaphambi kovavanyo lwe-flow cytometry? Ngaba kukho into ekufuneka ndiyoyike?

Kwiimeko ezininzi, ngaphandle kokuba ugqirha wakho ekunike imiyalelo ekhethekileyo, akukho lungiselelo likhethekileyo lifunekayo ngaphambi kolu vavanyo lwe-flow cytometry.

Ugqirha wakho uya kufuna isampuli yegazi, izicubu zomzimba, okanye umongo wamathambo ukuze enze olu vavanyo. Le sampuli idla ngokuthathwa eofisini kagqirha wakho ngexesha lotyelelo lwakho. Emva kokuba isampuli ithathiwe, ithunyelwa kwilabhoratri ukuze ivavanywe.

Nje ukuba ingcali yezifo igqibe uvavanyo lwe-flow cytometry, iya kuhlalutya idatha ize ithumele ingxelo kugqirha wakho ocele uvavanyo.

Eyona nto ibalulekileyo kukuba akukho mingcipheko eyaziwayo ngoku kuwe ngenxa yokwenza olu vavanyo lwe-flow cytometry. Ngoko ke musa ukuyoyika ngokungeyomfuneko le nto.

Zinjani iziphumo? Zisixelela ntoni?
