Kev sib txawv ntawm tib neeg chromosomes tuaj yeem tau txais thaum pH ntawm Giemsa stain hloov mus rau 9.0 los ntawm ib txwm 6.8.Xws li staining tso cai txheeb xyuas tag nrho cov khub homolog thiab cov cheeb tsam sib txawv hauv chromosome caj npab.Feem ntau, cov qauv zoo ib yam li qhov tau txais nrog quinacrine mustard fluorescence staining.Qee thaj chaw, xws li paracentric constrictions hauv chromosomes Al thiab C9, thiab qhov kawg ntawm caj npab ntev ntawm Y chromosome stain txawv nrog Giemsa 9 txheej txheem.Cov txheej txheem yog qhov yooj yim dua li cov txheej txheem quinacrine mustard fluorescence thiab kev txheeb xyuas cov homologs kuj yooj yim dua li cov hlwb stained tom kawg.
