Colloidal kub yog ib hom nanomaterial dav siv hauv immunolabeling tshuab.Colloidal kub thev naus laus zis yog cov cuab yeej siv ntau tshaj plaws, uas yog ib yam tshiab ntawm kev tiv thaiv kev tiv thaiv kab mob uas siv colloidal kub ua cov cim cim rau antigens thiab cov tshuaj tiv thaiv, thiab muaj nws qhov tshwj xeeb zoo.Nyob rau hauv xyoo tas los no, nws tau siv dav hauv ntau yam kev tshawb fawb lom neeg.Yuav luag tag nrho cov txheej txheem immunoblotting siv hauv tsev kho mob siv nws cov cim.Nyob rau tib lub sijhawm, nws tuaj yeem siv rau hauv kev khiav, electron microscopy, immunology, molecular biology thiab txawm biochip.

Colloidal kub yog qhov tsis zoo rau qhov tsis muaj zog alkali ib puag ncig, thiab tuaj yeem tsim kev ruaj ntseg nrog cov pab pawg zoo ntawm cov protein molecules.Vim tias daim ntawv cog lus no yog daim ntawv cog lus electrostatic, nws tsis cuam tshuam rau kev lom neeg ntawm cov protein.

Hauv cov ntsiab lus, daim ntawv lo ntawm colloidal kub yog txheej txheem encapsulation uas cov proteins thiab lwm yam macromolecules yog adsorbed rau saum npoo ntawm cov khoom kub colloidal.Qhov no spherical particle muaj zog muaj peev xwm adsorb proteins thiab tuaj yeem khi tsis-covalently rau staphylococcal A protein, immunoglobulin, toxin, glycoprotein, enzyme, tshuaj tua kab mob, tshuaj hormones, thiab bovine serum albumin polypeptide conjugates.

Ntxiv nrog rau kev khi cov protein, colloidal kub kuj tseem tuaj yeem khi rau ntau lwm yam macromolecules, xws li SPA, PHA, ConA, thiab lwm yam. Raws li qee lub cev muaj zog ntawm colloidal kub, xws li electron ntom ntom, particle loj, cov duab thiab xim, Ua ke nrog lub cev tiv thaiv kab mob thiab cov khoom siv roj ntsha ntawm cov ntawv khi, colloidal kub yog dav siv hauv kev tiv thaiv kab mob, histology, pathology thiab cell biology thiab lwm yam.
