FAQ：

Ua hōʻemi ʻia nā peptides i loaʻa iā Cys ma mua o ka hoʻouna ʻana?

Inā ʻaʻole ʻike ʻia ka peptide i hoʻokahe ʻia, ʻaʻole mākou e hōʻemi i ka Cys.Loaʻa nā polypeptides a pau mai nā huahana crude i hoʻomaʻemaʻe ʻia a lyophilized ma lalo o nā kūlana pH2, ka mea ma kahi liʻiliʻi e pale i ka oxidation o Cys.Hoʻomaʻemaʻe ʻia nā peptides i loaʻa iā Cys ma ka pH2 ke ʻole he kumu kikoʻī e hoʻomaʻemaʻe ai i ka pH6.8.Inā hana ʻia ka hoʻomaʻemaʻe ʻana ma ka pH6.8, pono e mālama koke ʻia ka huahana i hoʻomaʻemaʻe ʻia me ka waikawa i mea e pale ai i ka oxidation.Ma ka ʻanuʻu hoʻomalu maikaʻi hope loa, no nā peptides i loaʻa iā Cys, inā ʻike ʻia ka nui o ke kaumaha molekala (2P+H) ma ka palapala ʻāina MS, hōʻike ia ua hana ʻia kahi dimer.Inā ʻaʻohe pilikia me MS a me HPLC, e lyophilize pololei mākou a hoʻouna i nā waiwai me ka ʻole o ka hana hou ʻana.Pono e hoʻomaopopo ʻia ʻo nā peptides e loaʻa ana iā Cys e hoʻoheheʻe lohi i ka manawa, a ʻo ke kiʻekiʻe o ka oxidation e pili ana i ke kaʻina peptide a me nā kūlana mālama.

Pehea ʻoe e hoʻoholo ai inā pili ʻia kahi peptide?

Hoʻohana mākou i ka pane ʻo Ellman e hoʻāʻo ai inā ua pau ke apo.Inā maika'i ka ho'ā'o 'Ellman (melemele), 'a'ole i piha ka pane apo.Inā maikaʻi ʻole nā ​​hopena hoʻāʻo (ʻaʻole melemele), ua pau ka pane apo.ʻAʻole mākou e hāʻawi i ka hōʻike loiloi o ka ʻike cyclization no kā mākou mea kūʻai.ʻO ka mea maʻamau, aia ka wehewehe ʻana i nā hopena hoʻāʻo a Ellman ma ka hōʻike QC.

Pono wau i kahi peptide cyclic, aia kahi tryptophan, e hoʻoheheʻe ʻia?

ʻO ka oxidation o tryptophan he mea maʻamau i ka peptide oxidation, a ʻo ka peptides ka mea maʻamau ma mua o ka hoʻomaʻemaʻe ʻana.Inā hiki mai ka ho'ohāhā o tryptophan, e ho'ololi ka manawa pa'a o ka peptide ma ke kolamu HPLC, a hiki ke ho'opau 'ia ka oxidation e ka ho'oma'ema'e.Eia kekahi, hiki ke ʻike ʻia nā peptides oxidized e MS.

Pono anei e kau i kahi āpau ma waena o ka peptide a me ka wai?

Inā ʻoe e hoʻopili i kahi mole nui (e like me ka dye) i ka peptide, ʻoi aku ka maikaʻi o ka waiho ʻana i kahi ākea ma waena o ka peptide a me ka ligand e hōʻemi i ka hoʻopilikia ʻana i ka mea loaʻa ma o ka pelu ʻana o ka peptide ponoʻī a i ʻole ka pelu ʻana o ka peptide. kona conjugate.ʻAʻole makemake nā poʻe ʻē aʻe i nā wā āpau.No ka laʻana, i ka pelu ʻia ʻana o nā protein, hiki ke hoʻoholo i ka mamao o ke kaʻawale ʻana o ka hoʻopili ʻana o kahi waikawa amino ma o ka hoʻopili ʻana i kahi dye fluorescent i kahi kahua.

Inā makemake ʻoe e hana i kahi hoʻololi biotin ma ka pahu N, pono ʻoe e kau i kahi āpau ma waena o ka biotin a me ke kaʻina peptide?

ʻO ke kaʻina hana lepili biotin maʻamau i hoʻohana ʻia e kā mākou hui e hoʻopili i kahi Ahx i ke kaulahao peptide, a ukali ʻia e biotin.ʻO Ahx kahi pūhui 6-carbon e hana i ka pale ma waena o ka peptide a me ka biotin.

Hiki iā ʻoe ke hāʻawi i kekahi ʻōlelo aʻo e pili ana i ka hoʻolālā ʻana o nā peptides phosphorylated?

I ka piʻi ʻana o ka lōʻihi, e emi mālie ana ka hana hoʻopaʻa ʻana mai ka waikawa amino phosphorylated ma luna.ʻO ke kuhikuhi synthesis mai ka C terminal a i ka N terminal.Manaʻo ʻia nā koena ma hope o ka phosphorylated amino acid ʻaʻole i ʻoi aku ma mua o 10, ʻo ia hoʻi, ʻo ka nui o nā koena amino acid ma mua o ka phosphorylated amino acid mai ka N terminal a i ka C terminal ʻaʻole pono ma mua o 10.

No ke aha ka n-terminal acetylation a me C-terminal amidation?

Ke pale nei kēia mau hoʻololi i ka peptide mai ka hoʻohaʻahaʻa ʻia a ʻae i ka peptide e hoʻohālike i kona kūlana mua o nā alpha amino a me nā hui carboxyl i loko o ka protein makua.
