Amyloid β-Protein (1-28) / 109770-29-8 / GT Peptide / Peptide Supplier

Kev piav qhia

β-Amyloid (1-28) yog aβ-amyloid fragment uas tuaj yeem koom nrog hauv kev khi hlau.Beta-amyloid yog peptide uas tsim amyloid plaques hauv lub hlwb ntawm cov neeg mob Alzheimer's disease.1. Dissolve cov khoom Aβ peptide hauv txias hexafluoro-2-propanol (HFIP).Peptides tau incubated nyob rau hauv chav tsev kub rau tsawg kawg yog 1 h los tsim cov monomerization thiab randomization ntawm cov qauv.2. HFIP raug tshem tawm los ntawm evaporation thiab cov txiaj ntsig peptide tau khaws cia ua ib zaj duab xis ntawm -20 lossis -80° C. 3 Lub resulting daim nyias nyias tau yaj nyob rau hauv 5mM anhydrous DMSO thiab ces vortexed thiab diluted mus rau qhov tsim nyog concentration thiab buffer (nruab nrab tsis muaj ntshav thiab phenol liab).4 Tom ntej no, kev daws yog hnub nyoog ntawm 4-8° C rau 48 teev.Cov qauv tom qab ntawd centrifuged ntawm 14000g rau 10 min ntawm 4-8° C. Cov soluble oligomers nyob rau hauv lub supernatant.Tus supernatant tau diluted 10-rau 200-fold rau kev sim.

FAQ:

Cov lus qhia dab tsi yog tias kuv pib siv peptides?

Thaum npaj rau kev siv, ua raws li cov kauj ruam hauv qab no kom yaj cov peptides kom tswj tau lawv qhov zoo.

1, ua ntej qhib lub raj mis thiab hnyav ib feem ntawm peptide, cua sov kom ncav cuag chav tsev kub, thiab lub sij hawm cua sov yog pom zoo kom 1 teev.

2. Ceev nrooj ntsuas tus nqi uas yuav tsum tau muaj nyob rau hauv ib puag ncig huv si.

3. Khaws cov peptides ntxiv rau hauv lub freezer hauv qab -20℃, ntxiv desiccants thiab khaws cia rau hauv ib lub thawv airtight.

Kuv nyob txawv teb chaws, thiab nws yuav siv ob peb hnub rau kev xa khoom thiab kev lis kev cai.Qhov no puas yuav cuam tshuam rau kuv qhov kev tshawb fawb?

Koj tau txais cov peptides hauv lyophilized hmoov pob, thiab peptides feem ntau tuaj yeem khaws cia hauv chav sov yam tsis muaj kev puas tsuaj.Thov khov thiab khaws cia tam sim tom qab tau txais.

Cov teeb meem dab tsi yuav tsum tau them rau hauv cov txheej txheem khaws cia?

Cov peptide koj tau txais tau ntim rau hauv lyophilized hmoov.Peptides yog hydrophilic, thiab nqus dej yuav txo qhov kev ruaj ntseg ntawm peptide thiab txo cov ntsiab lus peptide.Thov xyuam xim rau cov hauv qab no: ua ntej, nrog cov desiccants, khaws cia rau hauv qhov chaw qhuav.Qhov thib ob, ib zaug tau txais, thov tam sim ntawd muab tso rau hauv lub freezer -20℃cia, nyob rau hauv thiaj li yuav tswj lub siab tshaj plaws stability.Thib peb, zam kev siv tsis siv neeg lub cev ua haujlwm ntawm lub freezer.Kev hloov pauv ntawm cov av thiab qhov kub thiab txias tuaj yeem cuam tshuam rau kev ruaj ntseg ntawm peptides.Plaub, qhov kub thiab txias sab nraud thaum lub sijhawm thauj mus los tsis cuam tshuam rau kev siv tau thiab zoo ntawm peptides.

Kuv yuav khaws cov peptides khov li cas thaum kuv tau txais cov khoom?

Thaum koj tau txais nws, koj yuav tsum khaws cia tam sim ntawd ntawm -20° C los yog qis dua.

Yog tias cov ntsiab lus peptide yog 80%, lwm yam 20% yog dab tsi?

Ntsev thiab dej

Yog tias peptide yog 98% ntshiab, 2% yog dab tsi?

Ob feem pua ​​​​ntawm cov muaj pes tsawg leeg tau raug txiav los yog tshem tawm cov kab sib txuas.

AMU unit yog dab tsi?

AMU yog micropolymerization unit.Qhov no yog chav ntsuas dav dav rau peptides.
