β-Amyloid (1-28) bụ aβ-amyloid iberibe nke nwere ike isonye na njide ígwè.Beta-amyloid bụ peptide na-emepụta plaques amyloid na ụbụrụ ndị ọrịa nwere ọrịa Alzheimer.1. Gbanyụọ ihe siri ike Aβ peptide na oyi hexafluoro-2-propanol (HFIP).A na-etinye peptide n'ime ụlọ okpomọkụ ma ọ dịkarịa ala 1 h iji guzobe monomerization na randomization nke ihe owuwu.2. E wepụrụ HFIP site na evaporation ma chekwaa peptide nke na-akpata dị ka ihe nkiri na -20 ma ọ bụ -80.° C. 3 A na-agbaze membranes ndị na-esi na ya pụta na 5mM anhydrous DMSO wee gbasaa ma gbanye ya na ntinye uche na nchekwa kwesịrị ekwesị (ọkara na-enweghị ọbara ọbara na phenol red).4 Na-esote, ihe ngwọta ahụ bụ agadi na 4-8° C maka awa 48.A na-etinye ihe nlele ahụ na 14000g maka nkeji 10 na 4-8.° C. The soluble oligomers nọ na supernatant.A na-agbaze ihe karịrị 10 ruo 200-fold maka nnwale.

FAQ:

Kedu ihe ndụmọdụ m ma ọ bụrụ na m malite iji peptides?

Mgbe ị dị njikere maka ojiji, soro usoro ndị dị n'okpuru ka igbari peptides iji nọgide na-adị mma.

1, tupu imeghe karama ahụ ma tụọ akụkụ nke peptide, kpoo ya ka ọ ruo ụlọ okpomọkụ, a na-atụ aro oge ikpo ọkụ ka ọ bụrụ 1 hour.

2. Ngwa ngwa tụọ ego achọrọ na gburugburu mpụga dị ọcha.

3. Chekwaa peptides fọdụrụ na friza n'okpuru -20℃, tinye ihe nchacha ma chekwaa ha n'ime akpa ikuku.

M na-ebi ná mba ọzọ, na ọ ga-ewe ọtụtụ ụbọchị maka mbufe na omenala mkpochapụ.Nke a ọ ga-emetụta nyocha m?

Ị na-enweta peptides na ngwugwu ntụ ntụ lyophilized, na peptides nwere ike ịchekwa ya na ụlọ okpomọkụ na-enweghị mmebi.Biko ifriizi ma chekwaa ozugbo ịnatachara ya.

Kedu nsogbu ndị ekwesịrị ịṅa ntị na usoro nchekwa?

Achịkọtara peptide ị nwetara na ntụ ntụ lyophilized.Peptides bụ hydrophilic, na ntinye mmiri ga-ebelata nkwụsi ike nke peptide ma belata ọdịnaya peptide.Biko ṅaa ntị na ihe ndị a: nke mbụ, na desiccants, echekwara na ebe akọrọ.Nke abụọ, ozugbo enwetara, biko tinye ozugbo n'ime friza -20℃nchekwa, iji nọgide na-enwe nkwụsi ike kachasị.Nke atọ, zere iji enweghị ọrụ ntu oyi akpaka nke friza.Mgbanwe na iru mmiri na okpomọkụ nwere ike imetụta nkwụsi ike nke peptides.Nke anọ, okpomọkụ dị n'èzí n'oge njem anaghị emetụta ịdị mma na àgwà nke peptides.

Kedu otu m ga-esi chekwaa peptides oyi kpọnwụrụ mgbe m nwetara ngwaahịa ahụ?

Ozugbo ị nwetara ya, ị ga-echekwa ya ozugbo na -20° C ma ọ bụ obere.

Ọ bụrụ na ọdịnaya peptide bụ 80%, gịnị bụ 20% ọzọ?
