2. Kauoha ma ka pūnaewele.E ʻoluʻolu e hoʻopiha i ka palapala kauoha ma ka pūnaewele.

3. Hāʻawi i ka inoa peptide, CAS No. a i ʻole ke kaʻina, ka maʻemaʻe a me ka hoʻololi inā makemake ʻia, ka nui, a me nā mea ʻē aʻe e hāʻawi mākou i kahi ʻōlelo i loko o 2 mau hola.

4. E kauoha i ka conformation e ka aelike kuai i kakau pono ia a me ka NDA (non disclosure agreement) a i 'ole ka aelike huna.

5. E hoʻomau mau mākou i ka holomua o ke kauoha i ka manawa.

6. Hāʻawi ʻia ka peptide e DHL, Fedex a i ʻole nā ​​​​mea ʻē aʻe, a me HPLC, MS, COA me ka ukana.

7. E hahai ʻia ke kulekele hoʻihoʻi inā he ʻokoʻa o kā mākou maikaʻi a lawelawe paha.

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

Pehea ʻoe e ʻike ai i ka maʻemaʻe o kahi peptide?

Hōʻike ʻia ka maʻemaʻe o ka peptide i ka hōʻike COA o ka huahana, e nānā i ka chromatogram.

ʻO nā huahana peptide Peptide Biochemical Limited e komo pū me ka loiloi?

I kā mākou hui, loaʻa nā huahana āpau i ka nānā maikaʻi piha, me MS, HPLC, solubility.Hiki ke noi ʻia nā hoʻokolohua kūikawā, e like me ka peptide content determination, amino acid analysis, etc.

Wahi a kekahi o lākou ʻo ACN, he aha ke ʻano o ia mea?

ʻO ka "ACN" he acetonitrile, i hoʻohana ʻia e kōkua i ka hoʻopau ʻana i kekahi mau peptides.

Pono ʻoe e hoʻopau i nā polypeptides i ka PH kūikawā?

E hōʻike ana ka hōʻike inā pono nā waiwai PH kūikawā.Inā loaʻa nā koi PH kūikawā, e ʻike ʻia kēia ma ka hōʻike COA.

He aha inā ʻaʻole e hoʻoheheʻe maikaʻi nā peptides?

Ma ke ʻano maʻamau, pono e hoʻoheheʻe ʻia ka peptide i ka wai distilled no ka manawa mua a ʻoi aku ka maikaʻi no ka disinfecting wai.Inā pilikia ka hoʻoheheʻe ʻana, e hoʻāʻo i kēia mau ʻanuʻu: Kōkua ka Sonic degradation e hoʻopau i nā peptides.E hoʻoheheʻe i ka hopena me kahi liʻiliʻi o ka acetic acid (10% ka hoʻonā) kōkua i ka hoʻopau ʻana i nā peptides maʻamau, a ʻo ka wai wai me ka amonia e kōkua i ka hoʻopau ʻana i nā peptides acidic.Manaʻo ʻia hoʻi e hoʻoheheʻe i ka peptide i kahi kiʻekiʻe kiʻekiʻe a laila hoʻoheheʻe ʻia i kāna ʻano hana maʻamau me ka wai a i ʻole buffer, no ka mea hiki i ka paʻakai ke hoʻoulu i ka polymerization.(No laila pono e hoʻohui ʻia ka buffer ma hope o ka pau ʻana o ka peptide.)

No ke aha i ʻokoʻa ai nā peptides i ka solubility?

He kūlana koʻikoʻi ka solubility no ka hoʻohana ʻana i nā peptides.Loaʻa i kēlā me kēia waikawa amino kona mau waiwai kemika intrinsic.No ka laʻana, he hydrophobic ka leucine, isoleucine, a me ka valerine, aʻo nā waikawa amino ʻē aʻe e like me lysine, histidine, a me arginine he hydrophilic.No laila, ʻokoʻa ka solubility o nā peptides ma muli o kā lākou haku mele.

Pehea ʻoe e hoʻopau ai i nā polypeptides?

Hōʻike ʻia ka solubility ma ka hōʻike COA o ka huahana.E ʻoluʻolu e heluhelu pono i nā kuhikuhi ma mua o ka hoʻomaka ʻana e hoʻoheheʻe.Hiki ke ʻokoʻa ka solubility ma muli o ke ʻano o ka peptide.ʻO ka hopena maʻamau ka hoʻoheheʻe ʻana i ka 1mg o ka peptide i 1ml o ka wai distilled.
