Amyloide β-Poroteyine (1-28) / 109770-29-8 / GT Peptide / Utanga Peptide

Ibisobanuro

β-Amyloide (1-28) ni aβ-igice cya amyloide gishobora kwitabira guhuza ibyuma.Beta-amyloide ni peptide ikora plaque amyloide mu bwonko bw'abarwayi barwaye Alzheimer.1. Kuraho bikomeye A.β peptide muri hexafluoro ikonje-2-propanol (HFIP).Peptide yashizwemo ubushyuhe bwicyumba byibura 1 h kugirango hamenyekane monomerisation na randomisation yimiterere.2. HFIP yakuweho no guhumeka hanyuma peptide yavuyemo ibikwa nka firime kuri -20 cyangwa -80° C4 Ibikurikira, igisubizo cyari gifite imyaka 4-8° C kumasaha 48.Ingero zahise zishyirwa kuri 14000g kuminota 10 kuri 4-8° C. Oligomers zishonga zari muri ndengakamere.Supernatant yavomwe inshuro 10 kugeza kuri 200 kugirango igerageze.

1. Contact us directly by phone or email: +86-13735575465, sales1@gotopbio.com.

2. Tegeka kumurongo.Nyamuneka wuzuze urupapuro rwabigenewe.

3. Tanga izina rya peptide, CAS Oya cyangwa urutonde, ubuziranenge no guhindura niba bikenewe, ubwinshi, nibindi tuzatanga cote mumasaha 2.

4. Tegeka guhinduka ukoresheje amasezerano yo kugurisha yasinywe byemewe na NDA (amasezerano yo kutamenyekanisha) cyangwa amasezerano yibanga.

5. Tuzakomeza kuvugurura iterambere ryateganijwe mugihe.

6. Gutanga peptide na DHL, Fedex cyangwa abandi, na HPLC, MS, COA bizatangwa hamwe n'imizigo.

7. Politiki yo gusubizwa izakurikizwa niba hari itandukaniro ryubwiza cyangwa serivisi.

8. Serivisi nyuma yo kugurisha: Niba abakiriya bacu bafite ikibazo kijyanye na peptide mugihe cyibigeragezo, nyamuneka twandikire natwe tuzagusubiza mugihe gito.

Ibicuruzwa byose byikigo bikoreshwa gusa mubushakashatsi bwubumenyi, ni's bibujijwe gukoreshwa mu buryo butaziguye n'abantu bose ku mubiri w'umuntu.

Ibibazo：

Ni izihe nama niba ntangiye gukoresha peptide?

Mugihe witeguye gukoreshwa, kurikiza intambwe zikurikira kugirango ushonga peptide kugirango ukomeze ubuziranenge.

1, mbere yo gufungura icupa no gupima igice cya peptide, shyushya kugirango ugere ku bushyuhe bwicyumba, kandi igihe cyo gushyuha kirasabwa kuba isaha 1.

2. Gupima vuba umubare ukenewe mubidukikije bisukuye.

3. Bika peptide isigaye muri firigo munsi -20℃, ongeramo desiccants hanyuma ubibike mubintu byumuyaga.

Ntuye mu mahanga, kandi bizatwara iminsi myinshi yo gutanga no gutumiza gasutamo.Ibi bizagira ingaruka kubushakashatsi bwanjye?

Wakira peptide mubipfunyika byifu ya lyofilize, kandi peptide irashobora kubikwa mubushyuhe bwicyumba nta byangiritse.Nyamuneka uhagarike kandi ubike ako kanya nyuma yo kwakira.

Ni ibihe bibazo bigomba kwitabwaho mugikorwa cyo kubika?

Peptide wakiriye yapakishijwe ifu ya lyofilize.Peptide ni hydrophilique, kandi kwinjiza amazi bizagabanya ituze rya peptide kandi bigabanye peptide.Nyamuneka nyamuneka witondere ibi bikurikira: ubanza, hamwe na desiccants, bibitswe ahantu humye.Icyakabiri, umaze kwakirwa, nyamuneka shyira muri firigo -20℃ububiko, kugirango ubungabunge umutekano ntarengwa.Icya gatatu, irinde gukoresha ikoreshwa ryubukonje bwikora bwa firigo.Imihindagurikire yubushyuhe nubushyuhe birashobora kugira ingaruka kuri peptide.Icya kane, ubushyuhe bwo hanze mugihe cyo gutwara ntibuhindura agaciro nubwiza bwa peptide.

Nigute nabika peptide ikonje mugihe nakiriye ibicuruzwa?

Umaze kubyakira, ugomba guhita ubibika kuri -20° C cyangwa munsi.

Niba peptide irimo 80%, izindi 20% nizihe?

Umunyu n'amazi

Niba peptide ifite 98% yera, 2% ni iki?

Ibice bibiri kw'ijana by'ibigize byaciwe cyangwa byasibwe ibice bikurikirana.

Igice cya AMU ni iki?

AMU nigice cya micropolymerisation.Nicyo gice rusange cyo gupima peptide.
