Ukora mubijyanye nubushakashatsi bwibinyabuzima? Niba aribyo, noneho ushobora kuba warumvise ibya Sulfo-NHS. Nkuko uruhare rukomeye rwuru ruganda mubushakashatsi rukomeje kumenyekana, uru ruganda rwinjira muri laboratoire nyinshi kwisi. Muri iki kiganiro, turaganira kuri Sulfo-NHS icyo ari cyo n'impamvu ari igikoresho cyagaciro cyane kubiga siyanse y'ibinyabuzima.
Ubwa mbere, Sulfo-NHS ni iki? Izina ni ndende-ndende, reka rero tuyice. Sulfo bisobanura aside sulfonike na NHS bisobanura N-hydroxysuccinimide. Iyo ibyo bice byombi bihujwe,Sulfo-NHSni Byakozwe. Uru ruganda rufite byinshi rukoreshwa mubushakashatsi bwibinyabuzima, ariko kimwe mubintu byingenzi ni ubushobozi bwo guhitamo poroteyine.
Sulfo-NHS ikora mugukora amine yibanze (ni ukuvuga amatsinda -NH2) kumurongo wuruhande rwibisigazwa bya lysine muri proteyine. Mu byingenzi, Sulfo-NHS ihuza poroteyine "tag", ikaborohereza kumenya no gusesengura mubushakashatsi butandukanye. Ibi byavuyemo ibice byinshi byubushakashatsi bushobora gutera imbere hamwe nukuri kandi kurwego rwo hejuru.
None, Sulfo-NHS ikoreshwa iki? Imikoreshereze imwe yuru ruganda ni mubushakashatsi bwikingira. Sulfo-NHS yerekanwe kuranga antibodiyite na antigene neza, ifungura inzira nshya zo kwiga ku ndwara z’umubiri n’indwara. Byongeye kandi,Sulfo-NHSIrashobora gukoreshwa mubushakashatsi bwimikorere ya protein-protein kuko ituma abashakashatsi bamenya vuba kandi byoroshye mugihe poroteyine ebyiri zikorana.
Ahandi hantu Sulfo-NHS ikoreshwa cyane ni proteomics. Proteomics yiga imiterere n'imikorere ya poroteyine zose mu binyabuzima, kandiSulfo-NHSni igikoresho cyingenzi muri iri sesengura. Mugushushanya poroteyine hamwe na Sulfo-NHS, abashakashatsi barashobora gukora ubushakashatsi kugirango babone amakuru arambuye kubyerekeye proteome y’ibinyabuzima runaka, ishobora noneho gufasha kumenya ibimenyetso bishobora kwanduza indwara.
Sulfo-NHS nayo igira uruhare mugutezimbere imiti mishya. Iyo abashakashatsi bagerageza gukora imiti mishya, ni ngombwa kumenya neza ko yibasira poroteyine yagenewe kandi atari izindi poroteyine mu mubiri. UkoreshejeSulfo-NHSguhitamo poroteyine, abashakashatsi barashobora kumenya intego nyayo yibiyobyabwenge bishobora gufasha kwihutisha iterambere ryibiyobyabwenge.
Ngaho rero ufite! Sulfo-NHS ntishobora kuba ijambo rizwi hanze yubumenyi, ariko iyi nteruro irihuta kuba igikoresho cyagaciro mubushakashatsi bwibinyabuzima. Kuva mubushakashatsi bwikingira kugeza kuri proteomics kugeza iterambere ryibiyobyabwenge, Sulfo-NHS ifasha abashakashatsi gutera imbere muri utwo turere kandi twishimiye kubona ibivumbuwe bizaza.
