8. ʻO ka lawelawe ma hope o ke kūʻai aku: Inā he nīnau kā mākou mea kūʻai e pili ana i kā mākou peptide i ka wā o ka hoʻokolohua, e ʻoluʻolu e kelepona iā mākou a e pane mākou iā ia i ka manawa pōkole.

Hoʻohana wale ʻia nā huahana a pau o ka hui no ka noiʻi ʻepekema, ʻo ia's pāpā ʻia e hoʻohana pololei ʻia e kekahi kanaka ma ke kino kanaka.

FAQ

He aha nā palena o ka lōʻihi o nā peptides synthetic?

ʻO ka polypeptide i hoʻohui ʻia e kā mākou hui he 6 ~ 50 amino acids ka lōʻihi.Hoʻopuka pinepine nā kaʻina hana solid-phase synthesis i nā peptides o 6 a 50 mau amino acids.

Pehea e wehewehe ai i nā piko P+Na a me P+K ma MALDI(MS)?

ʻIke pinepine ʻia nā kiʻekiʻe Na a me K ma MALDI, a ʻo ka sodium a me ka potassium mai ka wai hoʻoheheʻe.ʻO ka wai i hoʻoheheʻe ʻia a me ka wai deionized hiki ke loaʻa ka nui o ka sodium a me nā ion potassium ʻaʻole hiki ke wehe loa ʻia.Hoʻopili pū lākou a hoʻopaʻa i ka hui carboxyl manuahi o ka peptide i ka wā o ka spectrometry nui.No ka mea, ʻaʻohe ʻōnaehana hoʻomaʻemaʻe e wehe i nā ion sodium a me ka potassium mai ka wai, i kekahi manawa hiki ʻole ke ʻike ʻia nā piko sodium a me ka potassium ma ka palapala MALDI MS.

E ʻoluʻolu e wehewehe i kāu hoʻolālā hoʻomaʻemaʻe

Ua hoʻomaʻemaʻe ʻia nā peptides i hoʻohui ʻia e kā mākou hui e ka preparative reversed-phase HPLC me TFA a me pH 2 i hoʻohui ʻia i nā pae kelepona ʻelua.ʻO ka Phase A he 0.1% TFA i loko o ka wai ultra-pure, a ʻo ka pae B he 0.1% TFA ma ACN, pH 2. Hiki ke hoʻoheheʻe ʻia ka hāpana ma kahi ʻāpana A, a i ʻole hoʻoheheʻe ʻia i kahi wahi liʻiliʻi o ka māhele B a hoʻoheheʻe ʻia me ka pae A.I kekahi manawa pono paha e hoʻopau i nā peptides hydrophobic me nā mea hoʻoheheʻe ikaika e like me ka formic acid a i ʻole ka acetic acid, ma muli o ke kaʻina o ka peptide.Ma ka pH 6.8, paʻakikī loa ka hoʻoheheʻe ʻana a hoʻomaʻemaʻe i ka peptide, no laila e hoʻopau mua mākou i ka peptide a laila hoʻohana i ʻelua ʻāpana kelepona no ka gradient elution.ʻO ka hopena pale ma ka pH 6.8 he 10 mM ammonium acetate i loko o ka wai ultra-pure (mobile phase A), maʻemaʻe ACN (mobile phase B).Ua hōʻiliʻili ʻia nā ʻāpana like ʻole a ʻike ʻia e MADLI-TOF MS.Ua nānā ʻia ka maʻemaʻe e ka HPLC i hoʻohuli ʻia.A laila, ua lyophilized nā peptides target, a ua hui pū ʻia nā peptides lyophilized i loko o nā hue liʻiliʻi.

Pehea ʻoe e nānā ai i kāu huahana?

Ua nānā ʻia nā peptides synthetic āpau e HPLC a me MS, koe wale nō MALDIMS.No ka mea ua hoʻokaʻawale ʻia nā peptides i kā lākou mau kaʻina ponoʻī i nā spectrometers lehulehu, hiki ke hoʻohana ʻia nā ʻenehana HPLC-MS e kālailai i kēlā mau piko o ka ionization ma HPLC.ʻO kā mākou mea hana loea [MALDI-MS, HPLC-(ESI)MS (iion trap and tetrode array)] hāʻawi i ka hōʻoia hilinaʻi no ka nānā ʻana.

Pili ka solubility o ka peptide i ka maikaʻi o ka peptide?

ʻAʻole hoʻoheheʻe maikaʻi nā peptides synthetic, pilikia nā peptides, pololei?

A: He paʻakikī ke wānana pololei i ke ʻano o ka soluble o ka peptide a me ke ʻano o ka solvent kūpono.ʻAʻole ʻoiaʻiʻo he pilikia me ka peptide synthesis inā paʻakikī ke hoʻopau.

Pehea ʻoe e mālama ai i nā peptides i ka hopena?

Inā pono ʻoe e mālama i kāu peptides i loko o ka wai, e hoʻohana i kahi paʻi sterilized ma PH 5-6 a mālama i -20℃e hoʻolōʻihi i ke ola o kāu peptides i ka hopena.

Pehea ka lōʻihi o ka peptides i ka hopena?

ʻOi aku ka maikaʻi ʻaʻole e mālama i nā peptides koena i loko o ka hopena.ʻO ke ola o nā polypeptides i loko o ka hopena he palena loa, ʻoi aku ka poʻe me ka cysteine, methionine, tryptophan, asparagic acid, glutamic acid, a me N-terminal glutamic acid i ke kaʻina.Ma keʻano laulā, lawe i ka nui o ka hoʻohana pono ʻana, ʻo ke koena o ka pahu hau maloʻo no ka mālama lōʻihi.
