Streptavidin los ntawm Streptomyces avidinii CAS: 9013-20-1

Kev sib txuas lus: Streptavidin muaj kev sib txuas lus siab heev rau biotin, ua rau nws yog ib qho cuab yeej zoo heev rau kev ntes thiab nrhiav pom cov biotinylated molecules.

Kev ntxuav cov protein: Streptavidin feem ntau siv ua cov cuab yeej ntxuav hauv biotechnology. Cov cim biotinylated lossis cov molecule tuaj yeem txuas rau cov hlaws streptavidin, uas tso cai rau kev cais thiab ntxuav cov protein tshwj xeeb los ntawm cov khoom sib xyaw ua ke.

Kev ntsuam xyuas: Streptavidin feem ntau siv rau hauv kev ntsuam xyuas immunoassays, xws li enzyme-linked immunosorbent assays (ELISA), qhov twg nws tuaj yeem khi cov tshuaj tua kab mob lossis cov antigens biotinylated. Qhov no tso cai rau kev ntsuam xyuas rhiab heev thiab tshwj xeeb ntawm ntau yam protein lossis biomarkers.

Kev xa tshuaj rau lub hom phiaj: Streptavidin siv tau rau hauv cov txheej txheem xa tshuaj los ntawm kev sib txuas nrog cov neeg sawv cev kho mob lossis cov nanoparticles. Cov tshuaj biotinylated targeting molecules ces tuaj yeem txuas nrog streptavidin, pab txhawb kev xa tshuaj rau lub hom phiaj tshwj xeeb.

Cov txheej txheem molecular biology: Streptavidin siv rau hauv ntau yam txheej txheem molecular biology, xws li nucleic acid hybridization assays thiab polymerase chain reaction (PCR). Cov biotinylated probes lossis primers tuaj yeem siv los ntes lossis ua kom cov nucleic acids tshwj xeeb loj dua, thiab streptavidin tom qab ntawd siv los pom lossis ntes cov khoom biotinylated.

Kev Thaij Duab: Streptavidin feem ntau siv ua ib qho cuab yeej hauv kev siv lub tshuab tsom iav fluorescence thiab cov txheej txheem thaij duab. Los ntawm kev sib txuas cov xim fluorescent nrog streptavidin, cov hom phiaj tshwj xeeb tuaj yeem raug cim thiab pom tau nrog kev nkag siab siab thiab kev daws teeb meem.

Kev Kuaj Mob: Cov kev ntsuam xyuas uas siv Streptavidin yog siv dav hauv kev kuaj mob hauv chaw kho mob rau kev kuaj mob lossis cov kab mob sib kis. Cov biotinylated probes tuaj yeem ntes tau cov nucleic acids lossis antigens tshwj xeeb, ua rau kev kuaj mob thiab saib xyuas ntau yam mob.
