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

Incazelo

β-Amyloid (1-28) is aβ-i-amyloid fragment engabamba iqhaza ekubopheni insimbi.I-Beta-amyloid yi-peptide eyenza ama-amyloid plaque ebuchosheni beziguli ezinesifo i-Alzheimer's.1. Chaza okuqinile Aβ i-peptide ku-hexafluoro-2-propanol ebandayo (HFIP).Ama-peptides afakwa endaweni yokushisa yegumbi okungenani ihora elingu-1 ukuze kutholwe i-monomerization kanye ne-randomization yezakhiwo.2. I-HFIP yasuswa ukuhwamuka futhi i-peptide eyaba umphumela yagcinwa njengefilimu ku -20 noma -80° C. 3 Ulwelwesi oluwumphumela lwancibilika ku-5mM anhydrous DMSO futhi lwabuye lwavuthwa futhi lwahlanjululwa ekugxiliseni okufanelekile kanye ne-buffer (okumaphakathi okungenayo i-serum ne-phenol ebomvu).4 Okulandelayo, ikhambi lalineminyaka engu-4-8° C amahora angama-48.Amasampula abe esefakwa ku-14000g imizuzu eyi-10 ku-4-8.° C. Ama-oligomeri ancibilikayo ayeku- supernatant.I-supernatant yahlanjululwa ngokuphindwe ka-10 kuya kwezingu-200 ukuze kwenziwe ukuhlolwa.

Unga-oda Kanjani?

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

2. Oda ku-inthanethi.Sicela ugcwalise ifomu le-oda ku-inthanethi.

3. Nikeza igama le-peptide, Inombolo ye-CAS noma ukulandelana, ukuhlanzeka nokuguqulwa uma kudingeka, ubuningi, njll. sizohlinzeka ngekhotheshini kungakapheli amahora ama-2.

4. Ukugcinwa kwe-oda ngenkontileka yokuthengisa esayiniwe ngokufanelekile kanye ne-NDA(isivumelwano esingadalulwanga) noma isivumelwano esiyimfihlo.

5. Sizoqhubeka nokubuyekeza inqubekelaphambili ye-oda ngesikhathi.

6. Ukulethwa kwe-Peptide nge-DHL, i-Fedex noma abanye, kanye ne-HPLC, MS, COA izohlinzekwa kanye nempahla.

7. Inqubomgomo yembuyiselo izolandelwa uma kukhona ukushayisana kwekhwalithi noma isevisi yethu.

8. Isevisi yangemuva kokuthengisa: Uma amakhasimende ethu enemibuzo mayelana ne-peptide yethu ngesikhathi sokuhlolwa, sicela ukhululeke ukusithinta futhi sizoyiphendula ngokushesha.

Yonke imikhiqizo yenkampani isetshenziselwa inhloso yocwaningo lwesayensi kuphela, yona'kwenqatshelwe ukusetshenziswa ngokuqondile yinoma yimuphi umuntu emzimbeni womuntu.

FAQ:

Yiziphi izincomo uma ngiqala ukusebenzisa ama-peptide?

Uma usulungele ukusetshenziswa, landela lezi zinyathelo ezingezansi ukuze uncibilikise ama-peptide ukuze ugcine ikhwalithi yawo.

1, ngaphambi kokuvula ibhodlela nokukala ingxenye ye-peptide, yishise ukuze ufinyelele izinga lokushisa legumbi, futhi isikhathi sokushisa sinconywa ukuthi sibe yihora elingu-1.

2. Kala ngokushesha inani elidingekayo endaweni ehlanzekile yangaphandle.

3. Gcina ama-peptide asele efrijini ngezansi -20℃, engeza ama-desiccant bese uwagcina esitsheni esingangenisi umoya.

Ngihlala phesheya, futhi kuzothatha izinsuku ezimbalwa ukudiliva kanye nemvume yamasiko.Ingabe lokhu kuzoluthinta ucwaningo lwami?

Uthola ama-peptide kumaphakheji wempuphu e-lyophilized, futhi ama-peptides ngokuvamile angagcinwa endaweni yokushisa ngaphandle kokulimala.Sicela umise futhi ugcine ngokushesha ngemva kokuthola.

Yiziphi izinkinga okufanele zinakwe ohlelweni lokugcina?

I-peptide oyitholile ihlanganiswe ngempushana e-lyophilized.Ama-peptide ane-hydrophilic, futhi ukumuncwa kwamanzi kuzonciphisa ukuzinza kwe-peptide futhi kunciphise okuqukethwe kwe-peptide.Sicela unake lokhu okulandelayo: okokuqala, ngama-desiccants, agcinwe endaweni eyomile.Okwesibili, uma wathola, sicela ngokushesha ufake efrijini -20℃ukugcina, ukuze kugcinwe ukuzinza okukhulu.Okwesithathu, gwema ukusetshenziswa kwesiqandisi esizenzakalelayo sesiqandisi.Ukushintsha komswakama kanye nezinga lokushisa kungathinta ukuzinza kwama-peptide.Okwesine, izinga lokushisa langaphandle ngesikhathi sokuthutha akuthinti ukufaneleka kanye nekhwalithi yama-peptide.

Ngiwagcina kanjani ama-peptide afriziwe lapho ngithola umkhiqizo?

Uma usuyitholile, kufanele uyigcine ngokushesha ku -20° C noma ngaphansi.

Uma okuqukethwe kwe-peptide kungu-80%, yimuphi omunye u-20%?

Usawoti namanzi

Uma i-peptide imsulwa ngo-98%, yini u-2%?

Amaphesenti amabili okubhaliwe ancishisiwe noma asuswa izingcezwana zokulandelana.

Iyini iyunithi ye-AMU?

I-AMU iyunithi ye-micropolymerization.Lena iyunithi evamile yokulinganisa yama-peptide.
