Tom qab, lo lus nug yog, tshuaj tiv thaiv txiv tsawb ua haujlwm li cas? Ib cov noob pauv mus rau hauv lws suav lossis txiv tsawb tsob ntoo tau rov ua dua tshiab raws li cov protein ntau ntau zaug hauv cov txiv. Thaum noj nws nkag mus rau hauv txoj hnyuv thiab tom qab ntawd mus rau hauv cov hlab ntsha uas tsim cov tshuaj tiv thaiv kab mob siab B - ua haujlwm tib yam li ib txwm txhaj tshuaj tab sis kim dua tshuaj tiv thaiv.

Yuav kom ua tau zoo, cov tshuaj tiv thaiv yuav tsum tau ua kom muaj zog thiab tiv thaiv kab mob tshwj xeeb. Thaum cov antigen raug txheeb xyuas thiab cais tawm, cov noob yog cloned rau hauv ib qho kev hloov vector.
Leej twg tsim cov tshuaj tiv thaiv txiv tsawb?
“ Txiv tsawb tau tshawb nrhiav ib zaug rau lwm qhov kev siv biotech: tsim kom noj tau cov tshuaj tiv thaiv kab mob tawm tsam ntau yam tib neeg kab mob. Charles Arntzen, tus kws kho mob biotechnologist ntawm Arizona State University, tau xav txog kev tsim khoom txiv tsawb engineered los ua cov protein los ntawm cov kab mob uas ua rau tus kab mob cholera.
