SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), yog ib qho kev siv hluav taws xob tsis tu ncua tsim los ntawm Ulrich K. Laemmli uas feem ntau siv los ua ib txoj hauv kev los cais cov proteins nrog molecular masses ntawm 5 txog 250 kDa.

Thaum twg tau pom polyacrylamide gel electrophoresis?

Polyacrylamide gel (PAG) tau paub tias yog qhov muaj peev xwm embedding nruab nrab rau cov ntaub so ntswg thaum ntxov li xyoo 1964, thiab ob pawg neeg ywj pheej ua haujlwm PAG hauv electrophoresis hauv 1959.

Leej twg nrhiav tau gel electrophoresis?

Lub sijhawm xyoo 1930 Arne Tiselius tau tsim ib txoj hauv kev hu ua electrophoresis, uas ua rau siv qhov tshwm sim no cais cov tshuaj sib txawv ntawm ib leeg.

Leej twg cov kws tshawb fawb siv gel electrophoresis?

Gel electrophoresis tau dav siv hauv cov chaw kuaj mob molecular thiab biochemistry hauv thaj chaw xws li kev tshawb fawb txog kev tshawb fawb, kev txuag tsiaj, thiab tshuaj. Qee qhov kev siv tseem ceeb ntawm cov txheej txheem tau teev tseg hauv qab no: Hauv kev sib cais ntawm DNA tawg rau DNA ntiv tes los tshawb xyuas qhov xwm txheej txhaum cai.

Tus neeg no tau tshawb pom gel electrophoresis xyoo twg?

Gel electrophoresis yog ib qho yooj yim txheej txheem, qhia nyob rau hauv thaum ntxov 1970s, uas tiag tiag revolutionized cov kev tshawb fawb biophysical ntawm DNA thiab RNA thiab, tom qab, tag nrho cov teb ntawm molecular biology.
