Yooj yim staining tuaj yeem siv rau txhua hom kab mob hlwb los muab qhov sib piv rau lwm qhov tsis muaj xim ntawm tes txhawm rau txhawm rau txiav txim siab cell morphology, qhov loj me, thiab pab pawg ntawm tes. Cov txheej txheem no yog yooj yim vim tsuas yog ib qho dye siv thiab ncaj qha vim hais tias ntawm tes tiag tiag ua qias neeg.
Hauv qhov no, lub hom phiaj ntawm kev staining yooj yim hauv microbiology yog dab tsi?
Cov yooj yim stain tuaj yeem siv los txiav txim cov duab ntawm tes, qhov loj me, thiab kev teeb tsa. Muaj tseeb rau nws lub npe, lub yooj yim stain yog ib heev yooj yim staining txheej txheem uas tsuas yog ib qho stain . Txij li qhov saum npoo ntawm cov kab mob feem ntau raug them tsis zoo, cov stains zoo no tau nkag mus rau ntawm lub xov tooj ntawm tes.
Tsis tas li ntawd, cov stains ua haujlwm li cas hauv microbiology? Ntxiv rau rau fixation, staining yuav luag ib txwm siv rau xim tej yam ntxwv ntawm ib tug qauv ua ntej kuaj nws nyob rau hauv ib lub teeb microscope. Stains , los yog dyes, muaj ntsev ua los ntawm ib tug zoo ion thiab ib tug tsis zoo ion.
