FAQ：

I whakahekehia nga peptides kei roto Cys i mua i te tuku?

Mena karekau te peptide i kitea kua oxidized, kaore matou e whakaiti i te Cys.Ko nga polypeptides katoa ka riro mai i nga hua parakore kua purea me te lyophilized i raro i nga tikanga pH2, he iti rawa te aukati i te whakapouritanga o Cys.Ko nga Peptides kei roto Cys ka purea ki te pH2 mena kaore he take motuhake hei pure i te pH6.8.Mena ka mahia te purenga ki te pH6.8, me rongoa tonu te hua kua purea ki te waikawa kia kore ai e mate.I roto i te taahiraa whakahaere kounga whakamutunga, mo nga peptides kei roto Cys, ki te kitea te noho o te matū taumaha (2P+H) i runga i te mahere MS, e tohu ana kua hanga he dimer.Mena kaore he raruraru ki a MS me HPLC, ka tukuna e matou nga taonga me te kore he tukatuka atu.Me tohu ko nga peptide kei roto a Cys he puhoi te whakamaaramatanga i roto i te waa, a ko te tohu o te waiora ka whakawhirinaki ki te raupapa peptide me nga tikanga rokiroki.

Me pehea koe ki te whakatau mena he peptide kei te takahurihia?

Ka whakamahia e matou te tauhohenga a Ellman ki te whakamatautau mena kua oti te hanga mowhiti.Mena he pai te whakamatautau a Ellman (kowhai), kaore i oti te tauhohenga mowhiti.Mena he kino nga hua whakamatautau (kaore i te kowhai), kua oti te tauhohenga whakakai.Kaore matou e whakarato i te ripoata tātaritanga o te tohu tohu paihikara mo o taatau kiritaki.Ko te tikanga, he whakaahuatanga mo nga hua whakamatautau a Ellman i roto i te purongo QC.

Kei te hiahia ahau ki te peptide cyclic, kei roto he tryptophan, ka oxidized?

Ko te oxidation o te tryptophan he ahuatanga noa i roto i te peptide oxidation, a ko te nuinga o nga wa ka pahikohia nga peptides i mua i te purenga.Mena ka puta te oxidation o te tryptophan, ka huri te wa pupuri o te peptide i runga i te pou HPLC, ka taea te tango i te waiora ma te purenga.I tua atu, ka taea hoki te kite i nga peptides oxidized e MS.

Me whakatakoto he mokowhiti i waenga i te peptide me te waikano?

Mena kei te whakapiri koe i tetahi ngota ngota nui (penei i te waikano) ki te peptide, he pai ake te whakatakoto i te mokowhiti i waenganui i te peptide me te ligand hei whakaiti i te pokanoa ki te kaiwhiwhi ma te kopaki o te peptide ake, ma te kopaki ranei o te peptide. tona whakakotahitanga.Ko etahi kaore e hiahia ana ki nga waahi.Hei tauira, i roto i te whakakopa i nga pūmua, ka taea te whakatau he pehea te tawhiti o te hanga kopa o te waikawa amino ma te whakapiri i te waikano rewharewha ki tetahi waahi.

Mena kei te pirangi koe ki te whakarereke i te koiora i te tauranga N, me whakatakoto he mokowhiti i waenga i te biotin me te raupapa peptide?

Ko te tikanga tapanga biotin paerewa e whakamahia ana e to taatau kamupene ko te whakapiri i tetahi Ahx ki te mekameka peptide, ka whai ko te biotin.Ko Ahx he pūhui waro-6 e mahi ana hei arai i waenga i te peptide me te biotin.

Ka taea e koe te tuku tohutohu mo te hoahoa o nga peptides phosphorylated?

Ka piki haere te roa, ka heke haere te pai o te here mai i te waikawa amino phosphorylated ki runga ake.Ko te ahunga whakahiato mai i te tauranga C ki te tauranga N.E taunaki ana kia kaua e neke ake i te 10 nga toenga i muri i te waikawa amino phosphorylated, ara, ko te maha o nga toenga waikawa amino i mua i te waikawa amino phosphorylated mai i te tauranga N ki te tauranga C kia kaua e neke ake i te 10.

He aha te acetylation-n-terminal me te amidation-terminal C?

Ko enei whakarereketanga ka aukati i te peptide ki te whakaheke me te tuku i te peptide ki te whakataurite i tona ahuatanga taketake o nga roopu alpha amino me te carboxyl i roto i te pūmua matua.
