I-sodium chloride

I-sodium chloride

Inombolo ye-CAS: 7647-14-5

Igama elingaziwa: usawoti wetafula; usawoti wedwala

Igama lesibizo lesiNgisi: usawoti ovamile; usawoti wetafula; usawoti we-roch; usawoti wolwandle

Ifomula yama-molecule: i-NaCl

Isisindo sama-molecule: 58.44

Izakhiwo: ikristalu emhlophe, incibilika emanzini. Ku-25°C, i-1g iyancibilika emanzini angu-2.8ml, amanzi abilayo angu-2.6ml, kanye ne-glycerin engu-10ml, futhi cishe ayincibiliki ku-ethanol. Ukuncibilika kwayo emanzini kunciphisa ukuba khona kwe-hydrochloric acid, futhi cishe ayincibiliki ku-hydrochloric acid egxilile. Isixazululo samanzi asithathi hlangothi, sine-pH engu-5.0 ~ 8.0. Ubuningi obuhlobene 2.17. Iphuzu lokuncibilika 804℃. Iphuzu lokubila 1413℃. Isilinganiso esibulalayo esimaphakathi (igundane, ngomlomo) singu-3.75±0.43g/kg.

Indawo yokugcina: ivaliwe futhi igcinwe.

sebenzisa

1. I-reagent yokuhlaziya, esetshenziselwa ukuhlolwa kokufuthwa kukasawoti ukuthola ukumelana nokugqwala kwensimbi. Indinganiso yokulinganisa i-nitrate yesiliva. Ukunqunywa okuncane kwe-fluorine nama-silicates. Ukuhlolwa kwegazi okuvamile; ukuhlolwa kokusebenza kwesibindi, njll.

2. I-sodium chloride iyinto ebalulekile eyisisekelo yamakhemikhali, esetshenziswa kabanzi emikhakheni eminingi efana nemithi, izindwangu, ukuphrinta nokudaya, irabha, ukudla kanye nezolimo.

3. Isetshenziselwa ukulungiselela i-tris buffer, i-phosphate buffered saline, i-MPM-2 (mitotic protein monoclonal 2) cell lysis buffer, i-immunoprecipitation washing buffer, i-LB (Luria-Bertani) medium kanye ne-dialysis buffer

4. Isetshenziswa kabanzi ekulungiseleleni imithi futhi isetshenziswa njengesithako sokufaka uketshezi oluyimithamo, isithako sokugcwalisa noma sokumboza ngezindlela eziqinile zomthamo kanye nezinhlobo eziqinile zomthamo, isithako sokuxuba usawoti emithini kanye nama-capsule, isithako sokusabela okungokwemvelo, kanye nezinto zokusetshenziswa kwemithi.

5. Ezinhlelweni zezinto eziphilayo, i-sodium chloride iyi-electrolyte eyisisekelo engalungisa ingcindezi ye-osmotic, ibhalansi ye-pH kanye nokuqhuba kwayo. Idlala indima ebalulekile ekugcineni isakhiwo seprotheyini kanye nokukhuthaza umsebenzi we-enzyme. Kubalulekile ekuqiniseni ukwakheka kweprotheyini kanye nokuvuselela ukusabela kwamakhemikhali. kubalulekile.
