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

Tsanangudzo

β-Amyloid (1-28) ndiye aβ-amyloid fragment iyo inogona kutora chikamu mukusunga simbi.Beta-amyloid ndiyo peptide inoumba amyloid plaques muhuropi hwevarwere vane chirwere cheAlzheimer.1. Nyura iyo yakasimba Aβ peptide mukutonhora hexafluoro-2-propanol (HFIP).Peptides akaiswa pakamuri tembiricha kweinenge 1 h kumisikidza monomerization uye randomization yezvivakwa.2. HFIP yakabviswa ne evaporation uye peptide yakaguma yakachengetwa sefirimu pa -20 kana -80.° C. 3 Mishonga inoguma yakanyungudutswa mu 5mM anhydrous DMSO uye yakabva yanyungudutswa uye yakanyungudutswa kuhutano hwakakodzera uye buffer (yepakati isina serum uye phenol tsvuku).4 Tevere, mhinduro yaive yakura pa4-8° C kwemaawa makumi mana nemasere.Iwo samples akazoiswa centrifuged pa14000g kwemaminetsi gumi pa4-8.° C. Maoligomeri anonyunguduka aiva musimba guru.Iyo mashura yakadiridzwa kagumi kusvika ku200 kuti iedze.

Zvese zvigadzirwa zvekambani zvinongo shandiswa sesainzi yekutsvaga chinangwa, iyo'inorambidzwa kushandiswa zvakananga nemunhu chero upi zvake pamuviri wemunhu.

FAQ:

Ndezvipi zvinokurudzira kana ndikatanga kushandisa peptides?

Kana wagadzirira kushandiswa, tevera matanho ari pasi apa kunyungudutsa mapeptides kuchengetedza kunaka kwawo.

1, usati wavhura bhodhoro uye kuyera chikamu che peptide, pisa kuti usvike mukamuri tembiricha, uye nguva yekudziya inokurudzirwa kuve 1 awa.

2. Kurumidza kuyera chiyero chinodiwa munzvimbo yakachena yekunze.

3. Chengeta peptides yasara mufiriza iri pazasi -20℃, wedzera desiccants uye uzvichengete mumudziyo usina mhepo.

Ini ndinogara kunze kwenyika, uye zvinotora mazuva akati wandei kuti zviendeswe uye kubvumidzwa kwetsika.Izvi zvichakanganisa tsvagiridzo yangu here?

Iwe unogashira peptides mune lyophilized poda mapakeji, uye peptides anogona kazhinji kuchengetwa pakamuri tembiricha pasina kukuvara.Ndapota omesa uye chengeta pakarepo mushure mekugamuchira.

Ndeapi matambudziko anofanirwa kutariswa mune ekuchengetedza maitiro?

Iyo peptide yawakagamuchira yakaputirwa mu lyophilized powder.Peptides ndeye hydrophilic, uye kunyura kwemvura kunoderedza kugadzikana kwepeptide uye kuderedza peptide yemukati.Ndapota teerera kune zvinotevera: kutanga, ne desiccants, yakachengetwa munzvimbo yakaoma.Chechipiri, kana wangogamuchira, ndokumbirawo uise mufiriji -20℃kuchengetedza, kuitira kuchengetedza kugadzikana kwakanyanya.Chechitatu, dzivirira kushandiswa kweautomatic frost function yefiriza.Shanduko muhunyoro uye tembiricha inogona kukanganisa kugadzikana kwepeptides.Chechina, tembiricha yekunze panguva yekufambisa haina kukanganisa kutendeseka uye kunaka kwepeptides.

Ndinochengeta sei mapeptide akaomeswa nechando kana ndagamuchira chigadzirwa?

Kana wangoigamuchira, unofanira kuichengeta pakarepo pa -20° C kana pasi.

Kana iyo peptide yemukati iri 80%, imwe 20% ndeipi?

Munyu nemvura

Kana peptide iri 98% yakachena, 2% chii?

Zvikamu zviviri kubva muzana zvezvakaumbwa zvakadimburwa kana kudzimwa zvimedu zvakatevedzana.

Chii chinonzi AMU unit?

AMU ndiyo micropolymerization unit.Iyi ndiyo general unit yekuyera mapeptides.
