Khoom Description
Cov khoom ntawm Ethidium Bromide hmoov
Cov tshuaj sib xyaw ua ke rau CAS 1239-45-8 yog Ethidium Bromide (EB), siv dav siv nucleic acid stain hauv molecular biology. Nrog rau cov mis mos molecular ntawm C₂₁H₂₀BrN₃ thiab molecular hnyav ntawm 394.31 g / mol, nws zoo nkaus li ib qho tsw tsw tsw xim liab hmoov.
Ethidium Bromide nthuav tawm lub melting point ntawm 260-262℃(nrog rau decomposition), yog soluble nyob rau hauv dej (40 g / L ntawm 25 degree) thiab organic solvents xws li ethanol thiab acetone, thiab tsim ib tug tsaus liab aqueous tov. Nws cov qauv muaj lub nplhaib phenanthridine thiab bromide ion, ua rau txiv kab ntxwv - liab fluorescence emission nyob rau hauv 302 nm ultraviolet excitation.

Daim ntawv thov ntawm Ethidium Bromide CAS: 1239-45-8
Nyob rau hauv nucleic acid staining thiab tsom xam, EB ua hauj lwm raws li ib tug rhiab heev fluorescent dye rau pom DNA thiab RNA nyob rau hauv agarose los yog polyacrylamide gel electrophoresis. Los ntawm intercalating nruab nrab ntawm lub hauv paus khub ntawm nucleic acid ob strands, nws ho txhim kho cov teeb liab fluorescence, yooj yim saib thiab tsom xam ntawm nucleic acid fragment loj thiab tis.
