Cov txheej txheem ua ntej sov tuaj yeem siv los tiv thaiv qhov mob khaub thuas-reactive alloantibodies lossis autoantibodies los ntawm kev ua haujlwm hauv IAT theem
- siv cov qauv kuaj pom (C1qrs xav tau Ca ++ ions; EDTA, piv txwv li, chelates Ca++ thiab nres kev sib txuas ntxiv ntawm C1q)
- siv polyspecific AHG muaj ob qho tib si anti-IgG thiab anti-C3.
Vim li cas thiaj yuav tsum tau ua kom sov lub swb ua ntej siv?
Lub sov incubation txhawb kev dissociation ntawm cov tshuaj tiv thaiv los ntawm cov liab cell thiab lub sov so tiv thaiv nws los ntawm reattaching nyob rau hauv vitro. Txias autoantibodies tuaj yeem ua rau muaj qhov tsis zoo tshwm sim thaum lub sijhawm Rh (D) typing.
Yuav ua li cas ua ntej warmed?
(priːˈwɔːm) verb (transitive) to warm (something) ua ntej ntawm nws siv.
Peg puas txhim kho cov tshuaj tiv thaiv kab mob khaub thuas?
Ob theem: 1) Txheej ntawm cov hlwb ("sensitization") a) cuam tshuam los ntawm cov tshuaj tiv thaiv kab mob tshwj xeeb, electrostatic RBC tus nqi, qhov kub thiab txias, cov tshuaj tiv thaiv kab mob thiab cov tshuaj tiv thaiv kab mob b) Tsawg Ionic Strength Saline (LISS) txo qis cov nqi ntawm RBCs; tends txhim kho cov tshuaj tiv thaiv kab mob khaub thuas thiab autoantibodies c) Polyethylene glycol (PEG) …
Puas txias thiab tshuaj tiv thaiv kab mob tseem ceeb?
Cov tshuaj tiv thaiv kab mob khaub thuas feem ntau tsis tseem ceeb hauv chaw kho mob(piv txwv li, lawv tsis ua rau cov tshuaj hemolytic hloov pauv lossis kab mob hemolytic ntawm tus menyuam hauv plab / menyuam mos. Feem ntau cov tshuaj tiv thaiv kab mob khaub thuas yog hom IgM., uas piav qhia vim li caslawv tsis ua HDFN (IgM tsis hla cov placenta).

Thaum twg cov txheej txheem elicitation tuaj yeem siv cov kev hem thawj sab hauv?
Cov txheej txheem Elicitation tuaj yeem siv qhov twg? Technological advances cuam tshuam rau sab hauv kev hem los ntawm_. Ib tug neeg ua hauj lwm tseem tab tom thov cov ntaub ntawv nkag mus rau qhov project uas lawv tsis tau muab. Qhov twg siv tau cov txheej txheem elicitation xaiv txhua yam siv?
Dab tsi yog txheej txheej txheej txheem nyob rau hauv lub ntiaj teb?
Lub neej muaj txheej txheem ntawm lub ntiaj teb yog the Biosphere. Lub neej muaj dabtsi? Cov kabmob lub neej yog qhov tseem ceeb ntawm lub sijhawm ntev ntawm cov kabmob tuaj yeem xav tau ua raws li qhov xav tau hauv kev ua haujlwm ua ntej tau teev tseg.
Cov txheej txheem huab cua twg muaj txheej txheej ozone?
Feem ntau atmospheric ozone yog concentrated nyob rau hauv ib txheej nyob rau hauv the stratosphere, li ntawm 9 txog 18 mais (15 mus rau 30 km) saum lub ntiaj teb nto (saib daim duab hauv qab). Ozone yog ib qho molecule uas muaj peb lub atoms oxygen.
Cov txheej txheem vuam twg siv cov khoom siv hluav taws xob?
Cov txheej txheem hlau inert gas (MIG)siv cov khoom siv hluav taws xob, uas feem ntau yog nyob rau hauv daim ntawv ntawm tooj liab-coated coiled hlau. Argon yog siv los tiv thaiv cov vuam, thiab ncaj qha tam sim no nrog cov electrode yog qhov zoo los tsim kom muaj cua sov ntau rau melting.
Rau cov txheej txheem lossis cov txheej txheem?
Cov txheej txheem yog feem ntau yog ntau lub npe hais txog cov qauv uas tuaj yeem txiav txim siab. Nws cov lus yog cov qauv, tab sis cov pov thawj qhia tau tias cov txheej txheem feem ntau raug siv los ua cov lus thiab ntau ntau, zoo li cov ntaub ntawv thiab cov txheej txheem thiab lawv cov lus siv tsawg dua cov ntaub ntawv thiab cov txheej txheem.
