FAQ
Ua li cas koj thiaj paub qhov purity ntawm peptide?
Lub purity ntawm peptide yog qhia nyob rau hauv COA daim ntawv qhia ntawm cov khoom, xa mus rau lub chromatogram.
Peptide Biochemical Limited peptide cov khoom lag luam suav nrog cov kev tshuaj xyuas twg?
Nyob rau hauv peb lub tuam txhab, tag nrho cov khoom muaj tiav kev soj ntsuam zoo, nrog rau MS, HPLC, solubility.Kev ntsuam xyuas tshwj xeeb kuj tuaj yeem thov, xws li kev txiav txim siab cov ntsiab lus peptide, kev tshuaj xyuas amino acid, thiab lwm yam.
Ib txhia hais tias ACN, qhov ntawd txhais li cas?
"ACN" yog acetonitrile, uas yog siv los pab yaj qee cov peptides.
Koj puas yuav tsum tau yaj polypeptides ntawm PH tshwj xeeb?
Daim ntawv tshaj tawm yuav qhia seb puas yuav tsum muaj qhov tshwj xeeb PH.Yog tias muaj cov cai tshwj xeeb PH, qhov no yuav raug sau tseg hauv COA tsab ntawv ceeb toom.
Yuav ua li cas yog tias peptides tsis yaj zoo?
Nyob rau hauv txoj kev niaj zaus, peptide yuav tsum tau yaj hauv dej distilled thawj zaug thiab tsim nyog rau cov dej tua kab mob.Yog tias kev sib cais tseem muaj teeb meem, sim ua cov kauj ruam hauv qab no: Sonic degradation pab yaj cov peptides.Dilute kua nrog me me ntawm acetic acid (10% concentration) pab yaj peptides, thiab aqueous tov nrog ammonia pab yaj acidic peptides.Nws tseem pom zoo kom yaj cov peptide hauv qhov siab siab thiab tom qab ntawd dilute nws mus rau nws qhov kev ua haujlwm ib txwm muaj nrog dej lossis tsis muaj, vim tias ntsev tuaj yeem ua rau polymerization.(Yog li qhov tsis yuav tsum tau ntxiv tom qab peptide tau yaj tag.)
Vim li cas peptides txawv hauv solubility?
Solubility yog ib qho tseem ceeb rau kev siv peptides.Txhua cov amino acid muaj nws tus kheej cov khoom siv tshuaj lom neeg.Piv txwv li, leucine, isoleucine, thiab valerine yog hydrophobic, thaum lwm cov amino acids xws li lysine, histidine, thiab arginine yog hydrophilic.Yog li ntawd, peptides sib txawv muaj qhov sib txawv nyob ntawm seb lawv muaj pes tsawg leeg.
Yuav ua li cas yaj polypeptides?
Solubility yog teev nyob rau hauv COA daim ntawv qhia ntawm cov khoom.Thov nyeem cov lus qhia ua tib zoo ua ntej pib yaj.Solubility yuav txawv nyob ntawm seb hom peptide.Qhov kev daws teeb meem tshaj plaws yog kom yaj 1mg ntawm peptide hauv 1ml ntawm cov dej distilled.
