Neoantigen Peptide: ib qho tseem ceeb ntawm cov puzzle rau tus kheej immunotherapy uas
Vim li cas Neoantigen Peptide thiaj li kub?
Cov neeg uas ua cov qog tiv thaiv kab mob paub tias neoantigen yog cov khoom hloov pauv tshwj xeeb rau cov qog hlwb, uas tsis muaj nyob hauv cov hlwb li qub. Ua kom T-cells nrog neoantigens tuaj yeem tua cov qog thiab yuav tsis ua mob rau cov neeg dawb huv. Yog li ntawd, txawm nws yog tshuaj tiv thaiv qog los yog TCR-T kho, txhua tus tab tom nrhiav neoantigen.
Tab sis mus tom qab ib qho antigen tshiab, koj thawj zaug yuav tsum tau txais cov peptide. Qhov ntawd yog qhov peb ua - Neoantigen Peptide Synthesis.
Neoantigen Peptide kawm, dab tsi ua rau koj mob taub hau?
Peb tau tham nrog ntau pab pawg txhaj tshuaj thiab pom tias muaj ntau qhov mob tshwm sim:
Muaj ntau tus neeg sib tw peptides:tus neeg mob yuav raug tshuaj xyuas rau kaum ob lossis ntau pua qhov chaw hloov pauv, txhua qhov yuav tsum tau ua ke thiab sim, thiab kev ua haujlwm loj heev.
Peptide Length:Neoantigen Peptide feem ntau yog 15-25 amino acids, uas ntev dua li ib txwm luv peptide, thiab nws nyuaj rau kev sib txuas.
Lub sijhawm ua haujlwm ntev:Tos rau peptides yuav siv sij hawm ntev dua qhov kev sim, thiab qhov kev ua tiav ntawm qhov project yog rub nrog.
Tsis txaus purity:Kev sim ntawm tes yuav tsum tau purity, thiab cov txiaj ntsig tsis tuaj yeem nyeem tau yog tias muaj ntau dhau impurities.
Labeling yog yuav tsum tau:Qee zaum nws yog qhov tsim nyog los txuas biotin thiab fluorescent pawg, uas tsis tuaj yeem ua los ntawm cov tuam txhab synthesis zoo tib yam.
Peb qhov kev pabcuam Neoantigen Peptide synthesis tuaj yeem ua rau cov teeb meem no.
Peb yuav ua li cas
