Kev kuaj murexide yog cov txheej txheem tshuaj xyuas los txheeb xyuas qhov muaj caffeine thiab lwm yam purine derivatives hauv cov qauv. Cov tshuaj no tsis teb rau cov kev kuaj pom alkaloid xws li Dragendorff's reagent.
qhov taw qhia murexide yog dab tsi?
Murexide yog metal indicator for Ca, Co, Cu, Ni, Th, and rare earth metals; nws kuj yog ib tug colorimetric reagent rau calcium thiab tsawg ntiaj teb hlau. Murexide yog me ntsis soluble hauv dej, cawv, thiab ether. … Kev kuaj xyuas cov calcium yog pH 11.3, qhov siab tshaj plaws wavelength 506 nm thiab kuaj pom ntau yam 0.2-1.2 ppm.
Qhov ntsuas ntawm murexide yog dab tsi?
Siv. Murexide yog siv nyob rau hauv analytical chemistry raws li ib tug complexometric qhia rau complexometric titrations, feem ntau ntawm calcium ions, tab sis kuj rau Cu, Ni, Co, Th thiab tsawg-lub ntiaj teb hlau. Nws ua haujlwm li tridentate ligand.
Vim li cas murexide yog qhov taw qhia zoo?
Qhov taw qhia siv yog murexide uas yog xim sib txawv thaum freq piv rau nws cov xim thaum nws txuas nrog Ni2ions. Murexide yog qhov ntsuas tsim nyog vim nws khi tsawg zog rau Ni2ions dua li EDTA.
Dab tsi yog qhov hloov xim ntawm murexide qhia?
Murexide (ammonium purpurate) tau pom tias ua haujlwm raws li qhov taw qhia rau kev txiav txim siab complexometric ntawm Th. Ammonium purpurate tsim ib qho daj complex nrog Th uas hloov liab qab thaum ib qho kev poob qis ntawm EDTA ntxiv rau nws.

Dab tsi yog qhov sib txawv ntawm tus neeg tsis haum tshuaj thiab tus kws tshuaj tiv thaiv kab mob?
Tus kws tshuaj tiv thaiv kab mob kho cov teeb meem kev noj qab haus huv coj los ntawm kev tiv thaiv kab mob. Kuj tseem hu ua allergists, immunologists yog cov kws kho mob uas kuaj xyuas, kho, thiab ua haujlwm los tiv thaiv kev tiv thaiv kab mob .
Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Puas yog cov tshuaj tiv thaiv kab mob sib txuas tau suav tias yog kev tiv thaiv kab mob?
Antibody drug conjugates (ADCs) yog ib hom tshuaj tiv thaiv kab mob. Lawv yog tsim los ntawm peb yam: monoclonal antibody (mAb) thiab cytotoxic payload ua los ntawm cov kws khomob kws khomob, uas txuas nrog ua ke siv cov tshuaj sib txuas . Puas yog tshuaj tiv thaiv kab mob tib yam li kev tiv thaiv kab mob?
Dab tsi yog qhov tshuaj txhaj tshuaj tiv thaiv qib siab?
(1) Feem ntau. Lo lus "kev tsim nyog cov nqi txhaj tshuaj tertiary" txhais tau tias txhua tus nqi them lossis tshwm sim (txawm tias tsis them nyiaj rau tus as-qhauj) rau ib qho tshuaj txhaj tshuaj tertiary (tshwj tsis yog cov tshuaj hydrocarbon uas rov qab tau) uas yog siv.
Puas yog cov tshuaj tiv thaiv kab mob tiv thaiv kab mob ua rau lupus?
Antinuclear cov tshuaj tiv thaiv yog autoantibodies - cov tshuaj tiv thaiv kab mob uas tsom rau cov proteins ib txwm nyob hauv lub hauv paus ntawm lub cell. Qhov no dhau los ua qhov tseem ceeb hauv kev kho mob thaum ANAs teeb liab lub cevpib tsom nws tus kheej, uas tuaj yeem ua rau cov kab mob autoimmune, suav nrog lupus, Sjogren's syndrome, thiab cov kab mob sib xyaw ua ke .
