FAQ:

Shin peptides ɗin da ke ɗauke da Cys an rage kafin jigilar kaya?

Idan ba a sami peptide ya zama oxidized ba, gabaɗaya ba mu rage Cys ba.Ana samun duk polypeptides daga samfuran da aka tsarkake da lyophilized a ƙarƙashin yanayin pH2, wanda aƙalla ya hana iskar oxygenation na Cys.Peptides dauke da Cys ana tsarkake su a pH2 sai dai idan akwai takamaiman dalili don tsarkakewa a pH6.8.Idan ana yin tsarkakewa a pH6.8, samfurin da aka tsarkake dole ne a bi da shi tare da acid nan da nan don hana iskar oxygenation.A mataki na kula da inganci na ƙarshe, don peptides da ke ɗauke da Cys, idan an sami kasancewar nauyin kwayoyin halitta (2P + H) akan taswirar MS, yana nuna cewa an kafa dimer.Idan babu matsala tare da MS da HPLC, za mu kai tsaye lyophilize da jigilar kaya ba tare da wani aiki ba.Ya kamata a lura cewa peptides dauke da Cys suna yin jinkirin oxidation na tsawon lokaci, kuma matakin oxidation ya dogara da jerin peptide da yanayin ajiya.

Ta yaya za ku tantance idan an madauki peptide?

Muna amfani da amsawar Ellman don gwada ko samuwar zoben ya cika.Idan gwajin Ellman tabbatacce ne (rawaya), yanayin zoben bai cika ba.Idan sakamakon gwajin ya kasance mara kyau (ba rawaya ba), amsawar zoben ya cika.Ba mu bayar da rahoton bincike na gano keken keke ga abokan cinikinmu ba.Gabaɗaya, za a sami bayanin sakamakon gwajin Ellman a cikin rahoton QC.

Ina bukatan peptide na cyclic, wanda ya ƙunshi tryptophan, zai zama oxidized?

Rashin iskar oxygen na tryptophan abu ne na kowa a cikin peptide oxidation, kuma peptides yawanci ana yin hawan keke kafin tsarkakewa.Idan hadawan abu da iskar shaka na tryptophan ya faru, lokacin riƙewar peptide a kan ginshiƙi na HPLC zai canza, kuma ana iya cire iskar oxygen ta hanyar tsarkakewa.Bugu da ƙari, ana iya gano peptides oxidized ta MS.

Shin wajibi ne a sanya rata tsakanin peptide da rini?

Idan za ku haɗa babban kwayoyin halitta (kamar rini) zuwa peptide, yana da kyau a sanya sarari tsakanin peptide da ligand don rage tsangwama tare da mai karɓa ta hanyar nadewa peptide kanta ko ta nadewa. ta conjugate.Wasu ba sa son tazara.Misali, a cikin nadawa sunadaran, ana iya tantance nisan tsarin nadawa na amino acid ta hanyar makala rini mai kyalli zuwa wani wuri.

Idan kuna son yin gyaran biotin a tashar N, kuna buƙatar sanya rata tsakanin biotin da jerin peptide?

Daidaitaccen tsarin alamar biotin da kamfaninmu ke amfani da shi shine haɗa Ahx zuwa sarkar peptide, sannan biotin ya biyo baya.Ahx wani fili ne mai 6-carbon wanda ke aiki azaman shamaki tsakanin peptide da biotin.

Shin za ku iya ba da shawara kan ƙirar peptides phosphorylated?

Yayin da tsayin ya ƙaru, ƙimar ɗaurin a hankali yana raguwa daga amino acid phosphorylated zuwa gaba.Jagoran kira yana daga tashar C zuwa tashar N.Ana ba da shawarar cewa ragowar amino acid na phosphorylated kada su wuce 10, wato adadin amino acid kafin amino acid na phosphorylated daga tashar N zuwa tashar C kada ya wuce 10.

Me yasa n-terminal acetylation da C-terminal amidation?

Waɗannan gyare-gyare suna hana peptide daga lalacewa kuma suna ba da damar peptide ya yi kama da ainihin yanayin alpha amino da ƙungiyoyin carboxyl a cikin furotin iyaye.
