kutheni iplasma ingahlukani kwi-centrifuge
Intshayelelo
I-Centrifugation yindlela yelebhu esetyenziswa kakhulu ukwahlula izinto ezinobunzima obahlukeneyo. Isebenzisa umgaqo wamandla e-centrifugal ukwahlula izinto ngaphakathi komxube. Nangona kunjalo, kwimeko ye-plasma, i-centrifugation ayivelisi iileya ezahlukeneyo okanye ukwahlukana. Eli nqaku liphonononga izizathu zokungakwazi kwe-plasma ukwahlukana kwi-centrifuge kwaye licacisa iimpawu ezikhethekileyo zale nxalenye ibalulekileyo yegazi.
Ukuqonda iPlasma
I-Plasma, inxalenye engamanzi egazini, inamanzi, ii-electrolytes, iiproteni, iihomoni, kunye nezinye izinto ezahlukeneyo. Idlala indima ebalulekileyo ekugcineni i-homeostasis emzimbeni ngokuthutha izondlo, iihomoni, kunye nezinto ezilahlwayo. I-Plasma ikwaphethe ii-antibodies kwaye inceda ukulawula uxinzelelo lwegazi. Ukuqonda ukwakheka kunye neempawu ze-plasma kubalulekile ekufumaneni isizathu sokuba i-centrifugation ingabangela ukwahlukana kwayo.
Ukuqina kunye nobuninzi bePlasma
I-Plasma ibonisa iipropati zomzimba ezikhethekileyo ezithintela ukwahlukana kwi-centrifuge. Enye yezo mpawu yi-viscosity. I-Viscosity ibhekisa ekuchaseni kolwelo ukuhamba. I-Plasma ine-viscosity ephantsi, efana neyamanzi. Ngokungafaniyo nezinye izinto egazini, i-plasma ayinayo i-density ephezulu engayivumela ukuba yahlukane ngokufanelekileyo. Ngenxa yoko, xa iphantsi kwamandla e-centrifugation, i-plasma ayiphumeleli ukwenza iileya ezahlukeneyo.
Ukufana kwePlasma
I-Plasma yindlela efanayo, nto leyo ethetha ukuba ukwakheka kwayo kuhlala kufana kuyo yonke indawo. Ngokungafaniyo nee-suspensions, eziqulethe amasuntswana ahlukeneyo asasazeke kulwelo, i-plasma ayinazo izinto ezibonakalayo. Iquka ikakhulu ii-ions, iiproteni, kunye nezinyibilikisi ezenza umxube ofanayo. Xa i-centrifuged, i-homogeneity ithintela ukwakheka kwanoma yiziphi iileya okanye ukwahlukana.
Ukungabikho kweePellets okanye iiSediments
Ukwahlukanisa iiseli nge-centrifugation kuxhomekeke ekwahlukaniseni iiseli nge-centrifugation ngokusekelwe kubuninzi bazo. Egazini, iiseli ezibomvu zegazi kunye neeseli ezimhlophe zegazi zixinene kune-plasma kwaye zinokuhlulwa ngokufanelekileyo nge-centrifugation. Ezi seli zenza ii-pellets okanye ii-sediments ezantsi kwetyhubhu ngenxa yobuninzi bazo obuphezulu. Nangona kunjalo, i-plasma ayinazo ezo zicubu okanye ii-sediments, njengoko ngokuyintloko ithwala izinto ezinyibilikisiweyo. Ngaphandle kwezi zicubu zixineneyo, inkqubo yokwahlukanisa iiseli nge-centrifugation ayiphumeleli ukuvelisa naluphi na ulwahlulo okanye ukwakheka kwe-layer.
Indima ye-Anticoagulants
Enye into ethintela ukwahlulwa kwe-plasma kukusetyenziswa kwe-anticoagulants. Ukuze kufunyanwe i-plasma kwiimvavanyo ezahlukeneyo zelebhu, igazi lidla ngokuqokelelwa kwiityhubhu ezinee-anticoagulant agents. I-anticoagulants ithintela igazi ekujiyeni, njengoko zithintela izinto ezibangela ukujiya kwegazi ezifunekayo ekwakhekeni kwe-clot. Ngenxa yoko, igazi lihlala likwimo yalo yolwelo, lithintela ukwahlulwa kwe-plasma kwizinto zalo zeseli.
Isiphelo
Nangona i-centrifugation iyindlela esebenzayo yokwahlula iinxalenye ezinobunzima obahlukeneyo, i-plasma ibangela umngeni okhethekileyo ngenxa yeempawu zayo kunye nokwakheka kwayo. Ubunzima obuphantsi be-plasma, ukufana, ukungabikho kwamasuntswana axineneyo, kunye nokuba khona kwe-anticoagulants kuthintela ukwahlukana kwayo kusetyenziswa iindlela ze-centrifugation. Ukuqonda ezi mpawu kunceda abaphandi kunye neengcali zonyango basebenzise iindlela ezifanelekileyo zokwahlula i-plasma kunye nokufunda izinto zayo ngokufanelekileyo.
