Lub rab phom rab noob roj muaj ntxig qhov hauv noob los rau yam muaj sia?

Lub tshuab rab phom cov qauv los yog biolistic particle delivery system yog siv hauv biotechnology rau kev hloov kho cov nroj tsuag.

Nrog rau kev siv cov phom rab phom, cov noob rab phom txheej txheem muab cov DNA DNA lossis plasmid ncaj qha mus rau tus tswv tsev cog khoom. Lub payload yog ib qho me me ntawm ib qho hnyav ntawm cov hlau uas muaj nrog DNA. Cov txheej txheem no feem ntau kuj hu ua particle acceleration lossis microprojectile bombardment.

Lub tshuab phom rab phom tuaj yeem siv rau ntawm kev yub lossis cov nqaij mos ntawm lub hlwb. Ua ntej txhaj cov DNA rau cov cog cov ntaub so ntswg los ntawm cov noob rab phom, txawm tias muaj cov kub me me los yog tungsten hais tau ncaj rau nrog ntau pua cov ntawv theej ntawm cov noob. Qhov hais tawm tau yuam tawm mus rau hauv lub nucleus nrog lub noob rab phom.

Gene phom yog syringe hom khoom siv los tso DNA rau cytoplasm ntawm ib lub xovtooj ntawm. Nws 'tua' ib nanoparticle coated nrog DNA rau hauv lub cell. Ib zaug sab hauv cytoplasm, cov DNA sib xyaw ua ke nrog tus tswv tsev chromosome los ntawm mechansims nyiam recombination.
