Puratifomu Yekuvandudza Kushandiswa Kwevanhu Mukudzivirira Kurwara

Masoja ekudzivirira muviri akagadzirwa nevanhu anokonzera kupindura kushoma kana kusavapo kubva kumasoja ekudzivirira muviri evanhu. Sekureva kweCognitive Market Research, musika wepasi rose weAntibody Humanization iUSD 92.5 miriyoni muna 2024 uye uchakura nekukura kwegore negore (CAGR) kwe13.00% kubva muna 2024 kusvika 2031. Alpha Lifetech ine chikuva chehumanization chemaantibodies akakura, chine mwero wekubudirira weanopfuura 98% wema antibodies akagadzirwa nevanhu. Tine nzira dzakawanda dzehumanization, dzinosanganisira CDR grafting, SDR grafting, chain shuffling, phage display, nezvimwewo, zvinogona kusarudzwa zvichienderana nezvaunoda kuyedza. Hatingogone chete kupa humanization yema antibodies kubva kumarudzi akasiyana-siyana, akadai semakonzo, tsuro, alpacas, ngamera, nezvimwewo, asiwo humanization yema antibodies mumhando dzakasiyana-siyana, dzakadai se scFv, Fab, uye nanobodies. Tine vashandi vane hunyanzvi hwekugadzira, kuchenesa, uye kusimbisa masevhisi, kusanganisira kugadzirwa kwema mouse monoclonal antibody, kugadzirwa kwema chimeric antibody, humanized antibody expression and cleansing, uye humanized antibody characterization and analysis. Nekubudirira kukuru, kuchena kwakanyanya, uye kusasimba kwekudzivirira muviri, tinovimbisa kugadzirwa kwemasoja ekudzivirira muviri akagadzirwa nevanhu.

Nhanganyaya yeAntibody Humanization

Kurapa kweMonoclonal antibody kunogona kushandiswa kurapa zvirwere zve autoimmune, cancer, nezvimwe zvirwere. Ma monoclonal antibodies anogadzirwa nekubaya mbeva kana dzimwe mhuka. Kana ikashandiswa kurapa zvirwere muchikamu chekupedzisira chekugadzirwa kwe monoclonal antibody, immunogenicity ye non-human antibodies haigone kufuratirwa. Nheyo huru ye humanization ndeyekubatanidza non-human framework residues, dzakadai se hypervariable complementarity-determining regions (CDRs), mu human framework, zvichigadzira sequences dzinochengetedza hunhu hwepakutanga hwe antibody uku dzichidzivirira immunogenicity. Kubaya mbeva ne mouse sequence humanization inotevera inoramba iri nzira huru dzekuwana therapeutic antibodies, iyo inonyanya kupfuura nematanho akati wandei: kugadzirwa kwe mouse antibody, monoclonal antibody chimerization, chimeric murine human monoclonal antibody, uye maitiro ekugadzira fully humanized monoclonal antibody. Parizvino, tsvakurudzo inonyanya kusanganisira mbeva dzakachinja majini (transgenic genes) (transmitting human B cell genes into human B cell), high-throughput screening uchishandisa yeast kana phage display technology, CDR grafting (insert parent CDRs into human sequences), transplant-specific determination residues (SDR), framework shuffling, nedzimwe nzira.

Kubatanidza CDR

Kubatanidza CDR kunoitwa kuburikidza nehurongwa hwekutaura kwemhuka dzinoyamwisa hwakavakirwa patekinoroji yeDNA recombinant, uye matanho ayo makuru ndeaya:

(1) Gadzirai ma antibodies anoenderana mumbeva (kana kuti dzisiri dzevanhu), bvisai ma antibodies eDNA encoding, uye gadzirai ma virus kuti arongedzerwe (kana kuita zvakananga kurongedzerwa kwemasero rimwe chete).

(2) Kuona kutevedzana kweDNA kunoenderana neCDR yeantibody uye kuona hunyanzvi hwekubatanidza chinangwa;

(3) Sarudza nzvimbo yemuviri wemunhu (FR) yekuisa maCDR asiri evanhu uye kugadzira jini idzva remaantibody.

(4) Ita ongororo yemativi matatu yekusawirirana pakati pemaCDR asiri evanhu nemaFR evanhu kuti ugadzire shanduko dzekupora kuti usimbise loop uye kudzivirira kurasikirwa kwehukama kana kusimba kwechimiro cheantibody yekupedzisira yakagadzirwa semunhu.

Kuchinja-chinja kweFramework

Kusanganisa framework kunoshandisa tekinoroji yekuratidza ma phage uye tekinoroji yekuongorora ma phage library kuti vawane ma antibodies ane hukama hwakakura. Ma Oligonucleotides anokodha ma human antibody heavy chain frameworks anoshandiswa sema templates, CDR regions anokodha se primers, uye PCR amplification inoitwa kuti ibvise chigadzirwa chePCR kuti chiwane single-stranded DNA. Single-stranded DNA yemajini eVL neVH inonatswa ne streptavidin inovakwazve pama vectors uchishandisa T4 DNA ligase uye restriction enzymes, inoiswa mu bacteriophages, uye inowedzerwa ne bacteriophages, uye phage display library inovakwa. Kuongororwa katatu nema antigen anoenderana kunoitwa, uye ma clones akanaka anozosimbiswa uchishandisa ELISA nedzimwe nzira.

(Nzvimbo yekutarisa: Wang Yongmei, et al., Kuenzanisa kwe "framework shuffling" uye "CDR grafting" mukuita kuti PD-1 murine antibody ive munhu.)

Kuratidzwa kwePhage

Kugadzirwa kwema antibodies akagadzirwa nevanhu kunobva panzira yekuratidza ma antibodies chaiwo pamusoro pema bacteriophages, anonyanya kugadzirwa kuburikidza nema library e ma antibody phage e human antibody. Kwakabva library iyi ma PBMC akaparadzaniswa kubva muropa revanhu kuti agadzire ma library e ma phage, uko ma sequences anoenderana anoongororwa. Iyi sequence ine sequence yakakwana yevanhu, asi ma antibodies akagadzirwa i fragments e antibody, akadai se scFv, Fab, uye nanobody.
