Aashitada diethylene triamine pentaacetic acid CAS:67-43-6

Diethylene triamine pentaacetic acid (DTPA) waa isku-dhis kiimiko ah oo si caadi ah loogu isticmaalo sidii wakiil chelating ah. Waxay leedahay awood ay ku xidho ion-yada birta culus, gaar ahaan kuwa sida lead, mercury, iyo cadmium, si ay u sameeyaan isku-dhisyo deggan. DTPA waxaa loo isticmaalaa codsiyo kala duwan, oo ay ku jiraan hagaajinta deegaanka, daawaynta caafimaadka, hababka warshadaha, iyo dawooyinka radiopharmaceuticals. Sifooyinka ay u leedahay chelating birta ayaa ka dhigaya mid wax ku ool ah ka saarista biraha culus biyaha wasakhda ah, daaweynta sumowga birta culus, ka hortagga faragelinta falgalka kiimikada, iyo fududeynta keenista daawooyinka daaweynta ee bartilmaameedka ah. Guud ahaan, DTPA waa isku-dhisyo badan oo leh codsiyo muhiim ah oo warshado kala duwan ah.

Codsiga iyo Saamaynta

Joojinta RNases: Ujeeddada ugu weyn ee DEPC waa in la joojiyo RNases, kuwaas oo ah ensaymo burburin kara RNA. DEPC waxay la falgashaa haraaga histidine ee RNases, iyadoo wax ka beddesha goobahooda firfircoon oo ka dhigaysa kuwo aan firfircoonayn. Tani waxay hubinaysaa ilaalinta sharafta RNA inta lagu jiro tijaabooyinka sida go'doominta RNA, qoraalka dib u celinta, iyo taxanaha RNA.

Ilaalinta muunadaha RNA: Daaweynta DEPC waxaa badanaa lagu dabaqaa qalabka shaybaarka, sida tuubooyinka microcentrifuge, cidhifyada pipette-ka, iyo biyaha loo isticmaalo tijaabooyinka RNA. Tani waxay gacan ka geysaneysaa in la joojiyo wixii RNANases ah ee harsan ee laga yaabo inay jiraan iyo in laga hortago burburka RNA inta lagu jiro maaraynta iyo kaydinta muunadaha.

Diyaarinta reagent-ka aan RNAase lahayn: DEPC waxaa loo isticmaali karaa in lagu daaweeyo xalalka ama reagent-yada u baahan in aan RNAase lahayn, sida buffers-yada, xalalka Tris-EDTA (TE), ama biyaha loo isticmaalo tijaabooyinka bayoolajiga molecular-ka. Xalalkan la daweeyay ayaa markaa si ammaan ah loogu isticmaali karaa si loo yareeyo burburka RNA.

Wax-ka-beddelka DNA-da: DEPC waxay sidoo kale la falgeli kartaa kooxaha amino ee ku jira molecules-ka DNA-da, taasoo keenta wax-ka-beddelka carboethylated ee saldhigyada DNA-da. Tan waxaa loo isticmaali karaa codsiyada gaarka ah, sida fal-celinta taxanaha DNA-da ama wax-ka-beddelka DNA-da ee daraasadaha isku-xidhka.
