vim li cas cov ntshav centrifuge？ centrifuge tsim tawm | ZONELINK
Raws li peb txhua tus paub, kev sib cais cov serum yog ib qho teeb meem nyuaj, yog li yuav ua li cas centrifuge serum sib cais? Ua ntej tshaj plaws, peb tshuaj xyuas los ntawm lub tswv yim ntawm serum:
cov ntshav serum: Cov kua uas cais cov ntshav tom qab coagulation.
Lub ntsiab lus ntawm kev coagulation ntshav yog kev hloov pauv ntawm cov fibrinogen uas yaj tau mus rau hauv cov fibrin uas tsis yaj hauv cov ntshav. Cov protein fibrous yog cov filaments nyias nyias uas sib txuas ua ke rau hauv cov hlwb ntshav, tsim cov gel zoo li cov ntshav txhaws. 30 feeb txog 1 teev tom qab cov ntshav txhaws, cov ntshav txhaws hauv cov platelet systolic protein yuav raug txo qis, yog li cov ntshav txhaws rov qab los ua kom tawv, thiab cov kua ntshiab tawm los, hu ua serum. Serum txawv ntawm plasma vim nws tsis muaj fibrinogen thiab cov yam ntxwv clotting uas cuam tshuam rau cov ntshav txhaws, tab sis nws tau ntxiv me ntsis cov tshuaj uas platelets tso tawm thaum lub sijhawm clotting.
Yog li cia kuv rov qab mus rau lub hom phiaj ntawm kev sib cais serum
Cov ntaub ntawv dav dav:
Sawv ntawm qhov kub thiab txias hauv chav tsev (37 degrees) rau ntau tshaj ib nrab teev, tig lub centrifuge, thiab centrifuge ntawm 3500-4000rpm rau 5-10 feeb. Cov serum raug rho tawm. Yog tias ntsuas cov enzymes thiab lwm yam ntsuas yooj yim rau degrade, raws li qhov xav tau los tso 4 degrees rau ntau tshaj ib nrab teev, centrifuge. (Lub hom phiaj ntawm kev tso nws ntawm 37 degrees rau ib pliag yog kom cia cov ntshav coagulate thiab tso cov serum, vim tias thaum cov ntshav coagulates, cov fibrin cog lus thiab cov serum tso tawm.)
Cov teeb meem uas xav tau kev saib xyuas
1 Qhov ceev centrifugal loj dhau, yooj yim ua rau hemolysis
2 Cov ntshav tsiaj, sim tsis txhob lo rau cov plaub hau, yooj yim rau hemolysis.
Cov Lus Qhia: Tom qab tshem cov ntshav tawm, tsis txhob muab lub thawv tso ncaj, tiaj tus lossis qaij, kom cov serum tuaj yeem nthuav dav thaj chaw nag, ua rau cov serum nag.
Hauv kev xaus lus, qhov teeb meem tseem ceeb yog khaws cov ntshav kom zoo, nkag siab txog qhov kub thiab txias hauv chav, thiab tom qab ntawd siv lub centrifuge tshwj xeeb los cais cov serum, txhawm rau kom tsis txhob muaj hemolysis.
