IPHASE Zvigadzirwa

Masero eCD19 B ihombe yelymphocyte subset musimba remuviri wemunhu uye anoshandiswa zvakanyanya mune zvese zviri zviviri tsvakiridzo nezvidzidzo zvekushandura. Mumafambiro mazhinji ekuedza, CD19 B masero anotorwa kubva kuPBMC, zvichiita kuti PBMC ive yekutanga yekutanga zvinhu zveB cell hupfumi. Masero eCD19 B anomiririra chikamu chidiki chidiki chePBMC, asi akakosha zvakanyanya pakugadzirwa kwemasoja ekudzivirira chirwere, kudzora kudzivirirwa kwezvirwere, uye kuenzanisira kwechirwere. Nekuda kweizvi, CD19 B masero anowanzo kuparadzaniswa achishandisa immunomagnetic tekinoroji kuve nechokwadi chepamusoro kuchena uye kushanda kwekuvimbika.

PBMC seNzvimbo Yekutanga yeCD19 B Cells

PBMC ine huwandu hwakasiyana-siyana hwemamononuclear immune cell, anosanganisira T masero, NK masero, monocytes, uye CD19 B masero. Mukati memusanganiswa uyu, masero eCD19 B anowanzo kuvepo pakaderera frequency, izvo zvinoita kuti kuongorora kwakananga kuve kwakaoma pasina kupfumisa. Naizvozvo, PBMC inoshanda seyakajairwa sosi zvinhu zveCD19 B masero ega. Mune akawanda marabhoritari workflows, CD19 B masero anotanga kupfumiswa kubva kuPBMC asati ashandiswa muzasi maapplication akadai seyekuyerera cytometry, RNA sequencing, kana inoshanda assays.

Hukama huri pakati pePBMC neCD19 B masero hwakakosha mukutsvaga kweimmunology. PBMC inopa nharembozha, nepo maCD19 B masero anomiririra huwandu hwevanhu vakatorwa kubva muhurongwa uhu. Kupatsanurwa kwakanaka kweCD19 B masero kubva kuPBMC kwakakosha pakuburitsa data rekuyedza rakavimbika.

CD19 B Cell Magnetic Bead Isolation Strategy

CD19 B cell isolation inowanzoitwa pachishandiswa magineti bead-based separation technologies. Masisitimu aya anovimba nemasoja ekudzivirira chirwere-mabhedhi akasanganiswa anosungirira kumasero eCD19 B mukati mePBMC. Kana yangonyorwa, masero eCD19 B anogona kupatsanurwa achishandisa magineti, achibvumira kukurumidza kupfumisa nezvinhu zvishoma zvinodiwa.

Muchirevo chechinyorwa chino, CD19 B masero ega anogona kuitwa kuburikidza nesarudzo yakanaka kana kusarudzwa kwakashata. Sarudzo yakanaka inobata zvakananga CD19 B masero kubva kuPBMC uchishandisa CD19-kunongedza magineti bead. Iyi nzira inoguma nemaCD19 B masero akakwenenzverwa akakodzera kune akawanda ezasi maapplication. Mukupesana, kusarudzwa kwakashata kunobvisa asiri - B maseru kubva kuPBMC, ichisiya isina kubatwa maCD19 B masero munzvimbo yavo yekuzvarwa. Mazano ese ari maviri anoshandiswa zvakanyanya, zvichienderana nekuti kuyedza kwepasi kunoda kutendeseka kwekugamuchira kana kuchena kwakanyanya.

Positive Selection uye Negative Sarudzo yeCD19 B Masero

CD19 B cell positive sarudzo inoshanda zvakanyanya pakuwana pure B cell populations. Nenzira iyi, masero eCD19 B anonyorwa zvakananga uye anochengetwa mundima yemagineti, zvichiita kuti kukurumidza kupfumiswa kubva kuPBMC. Iyi nzira inonyanya kubatsira kana kuchena kwakanyanya kuchidikanwa, senge muCD19 B cell functional assays kana transcriptomic profiling.

CD19 B cell negative kusarudzwa, kune rumwe rutivi, yakagadzirirwa kuchengetedza CD19 B masero pasina kusungirirwa kwemasoja ekudzivirira. Nenzira iyi, mamwe marudzi emasero ekudzivirira anopera kubva kuPBMC, kusanganisira T masero, NK masero, uye monocytes, nepo CD19 B masero anoramba asina kuchinjwa. Iyi nzira inosarudzwa paunenge uchidzidza CD19 B cell activation, nzira dzekusaina, kana antigen kupindura, sezvo ichidzikisira kubatanidzwa kwekugamuchira.

Ose ari maviri CD19 B sero sarudzo yakanaka uye CD19 B masero asina kusarudzwa anogamuchirwa zvakanyanya mukutsvagisa immunology yevanhu, uye nzira mbiri dzinotanga nePBMC sechinhu chekutanga.

Immunomagnetic Separation uye Yekuedza Zvishandiso

Immunomagnetic separation ndiyo musimboti tekinoroji kuseri kweCD19 B cell kuparadzaniswa. Inopa nzira yekukurumidza uye inoparadza yekupfumisa maCD19 B masero kubva kuPBMC uku ichichengetedza kushanda kwepamusoro. Kushandiswa kweantibody-yakavharidzirwa magineti mabedhi inogonesa kusungirira, ichiteverwa nekupatsanurwa kwakanaka uchishandisa magineti makoramu kana maraki.

Mushure mekuparadzaniswa, masero eCD19 B anogona kushandiswa mumhando dzakasiyana-siyana dzepasi, kusanganisira immune phenotyping, cytokine secretion analysis, B cell receptor zvidzidzo, uye kuwanikwa kweantibody. Hunhu hweCD19 B masero ekuzviparadzanisa nevamwe hunokanganisa zvakananga kuyedza kuberekana, kuita optimization yePBMC kubata uye kupatsanura mapuroteni akakosha pakubudirira kwetsvagiridzo.

Workflow Optimization kubva kuPBMC kuenda kuCD19 B Masero

Mumafambiro emurabhoritari akajairwa, PBMC inotanga yakatsaurwa kubva kusampuli dzeropa revanhu uye yozoshandiswa sechipo chekuwedzera masero eCD19 B. Kushanda kweCD19 B sero kuparadzaniswa kunoenderana nezvinhu zvakaita sePBMC hunhu, bead kusunga zvakanaka, uye sarudzo sarudzo (yakanaka kana yakaipa sarudzo). Yepamusoro - gadziriro dzePBMC dzemhando yepamusoro dzinotungamira mukuvandudzwa kweCD19 B cell goho uye kuchena.

Pakazere, CD19 B masero ekuzviparadzanisa nevamwe kubva kuPBMC inzira yekona muhutano hwemunhu. Kungave uchishandisa CD19 B cell sarudzo yakanaka kana CD19 B sero sarudzo isina kunaka, vaongorori vanovimba nePBMC senzvimbo yakakosha yekutangira pakugadzira inoshanda maCD19 B maseru akakodzera kune dzakasiyana siyana dzekuyedza maapplication.

Q1: Ndehupi hukama pakati peCD19 B masero nePBMC?

CD19 B masero iboka diki rePBMC. PBMC ine akawanda immune cell marudzi, anosanganisira T masero, NK masero, monocytes, uye CD19 B masero. Masero eCD19 B anomiririra chikamu chidiki chidiki chePBMC uye anowanzo pfumiswa kubva kuPBMC pakuedza kuzasi.

Q2: CD19 B cell isolation inoshandiswa nei?

CD19 B cell isolation inoshandiswa kuwana akacheneswa zvakanyanya B masero ekutsvagisa immunology. Masero eCD19 B anowanzo kuparadzaniswa kubva kuPBMC kumashandisirwo akadai sekuyerera cytometry, RNA sequencing, kuwanikwa kwemasoja ekudzivirira chirwere, uye inoshanda yekudzivirira immune assays.

Q3: Ndeupi mutsauko pakati pesarudzo yakanaka uye yakaipa yeCD19 B masero?

CD19 B cell positive sarudzo inobata zvakananga CD19 B masero achishandisa antibody-yakavharidzirwa magineti mabedhi, zvichikonzera kuchena kwakanyanya. CD19 B cell negative selection inobvisa asiri-B masero kubva kuPBMC, ichisiya maCD19 B macell asina kubatwa mune imwe nyika. Nzira mbiri idzi dzinoshandiswa zvakanyanya zvichienderana nezvinodiwa zvekuedza.

Q4: Sei PBMC ichiwanzo shandiswa CD19 B sero kuparadzaniswa?

PBMC ndiyo yakajairwa kutanga zvinhu nekuti inowanikwa zviri nyore kubva muropa remukati uye ine ese makuru emononuclear immune cell, kusanganisira maCD19 B masero. Kushandisa PBMC kunobvumira hupfumi hweCD19 B masero kuburikidza nemagineti bead-based separation systems.

Q5: Ndeapi maapplication anoshandisa CD19 B masero akaparadzaniswa nePBMC?

Masero eCD19 B akaparadzaniswa kubva kuPBMC anoshandiswa zvakanyanya mukutsvaga kwekudzivirira kwezvirwere uye biomedical, kusanganisira B cell receptor kuongororwa, cytokine secretion studies, immune profiling, uye kurapa masoja ekudzivirira chirwere. Hunhu hweCD19 B masero ekuzviparadzanisa nevamwe hunokanganisa zvakananga kudzika kwekuyedza kuvimbika.
