Ityuwa yesodium ye-5-Bromo-4-chloro-3-indolyl-beta-D-glucuronide CAS:129541-41-9
Ityuwa yesodium ye-5-Bromo-4-chloro-3-indolyl-beta-D-glucuronide yikhemikhali esetyenziswa kakhulu kuphando lwelabhoratri kunye nokuxilongwa. Idla ngokubizwa ngokuba yi-X-Gluc kwaye isetyenziswa kakhulu njengesiseko sokubona umsebenzi we-enzyme ye-beta-glucuronidase.
Xa i-beta-glucuronidase ikhona, iyawuqhawula umxokelelwane we-glucuronide kwi-X-Gluc, nto leyo ephumela ekukhululweni kwedayi eluhlaza okwesibhakabhaka ebizwa ngokuba yi-5-bromo-4-chloro-3-indolyl. Le mpendulo idla ngokusetyenziselwa ukubona ngokubonakalayo okanye nge-spectrophotometric ukubonakaliswa kwe-enzyme ye-beta-glucuronidase kwiiseli okanye kwizicubu.
Uhlobo lwetyuwa yesodiyam ye-X-Gluc luphucula ukunyibilika kwayo kwizisombululo zamanzi, nto leyo eyenza kube lula ukusetyenziswa kwayo kwiimvavanyo zelebhu. I-X-Gluc isetyenziswa kakhulu kuphando lwebhayoloji yeemolekyuli ukufunda ukubonakaliswa kwezakhi zofuzo, umsebenzi wokukhuthaza, kunye novavanyo lwezakhi zofuzo ze-reporter. Ingasetyenziselwa nokufumanisa ubukho bezinto eziphilayo ezivelisa i-beta-glucuronidase, ezifana neebhaktheriya ezithile, kwizifundo ze-microbiological.

I-1,4-Dithioerythritol (DTE) CAS:6892-68-8
I-Dithioerythritol (DTE) yikhompawundi esetyenziswa kakhulu kuphando lwebhayoloji ye-biochemical kunye ne-molecular biology. Yinto yokunciphisa enokukwazi ukuphula ii-disulfide bonds, ezibalulekileyo kwisakhiwo seprotheyini kunye nokuzinza. I-DTE iluncedo kakhulu ekulungiseleleni iisampulu kunye nokucocwa kweprotheyini njengoko inceda ukugcina iiprotheyini kwiifom zazo ezinciphileyo nezisebenzayo. Ingasetyenziselwa ukukhusela amaqela e-thiol kwiiprotheyini kwi-oxidation. Ukongeza, i-DTE ineempawu ze-antioxidant kwaye inokususa ii-free radicals, nto leyo eyenza ukuba ibe luncedo kwiimvavanyo ezahlukeneyo zoxinzelelo lwe-oxidative.

I-Hydrogenated Tallowamine CAS: 61788-45-2
I-hydrogenated tallowamine yikhemikhali eyinxalenye yosapho lwe-amine. Ivela kwi-tallow, enamafutha afumaneka kwizilwanyana. I-hydrogenated tallowamine isetyenziswa kakhulu kumashishini ahlukeneyo kunye nokusetyenziswa kwayo ngenxa yeempawu zayo ze-surfactant.
Njenge-surfactant, i-hydrogenated tallowamine iyakwazi ukunciphisa uxinzelelo lomphezulu wolwelo, nto leyo evumela ukuba lusasazeke ngokulula nangokulinganayo. Oku kuyenza ibe sisithako esifunekayo kwiimveliso ezifana neesepha, izithambisi zelaphu, kunye neearhente zokucoca, apho inceda ukuphucula iimpawu zokucoca kunye nokukhupha amagwebu. Ukongeza, i-hydrogenated tallowamine ingasebenza njengearhente yokuxuba, inceda ukuzinzisa imixube yeoyile namanzi, okanye ezinye izinto ezingadibaniyo. Oku kuyenza ibe luncedo ekuqulunqweni kwezinto zokuthambisa, iipeyinti, kunye neemveliso zezolimo, apho yenza kube lula ukusasazwa ngokulinganayo kwezithako kwaye iphucule ukusebenza kwemveliso iyonke.
