Western blotting - Guías de estudio, Notas de estudios & Resúmenes

Western blotting a. Proteins from SDS-PAGE are transferred to a nitrocellulose membrane using electrical current a. membrane is blocked so antibody will not bind nonspecifically b. Primary antibody is added and incubated with the membrane c. To detect antibodies that have bound to protein a secondary anti-immunoglobulin antibody coupled to a reporter a. Excess secondary antibody is washed off the membrane b. Substrate is added that precipitates upon reaction c. Reveals visible band where...

MCAT - Lab Techniques (MilesDown)Native-PAGE - correct answer A polyacrylamide gel electrophoresis method for proteins using NON-DENATURING conditions. Proteins keep their native charge and structure so they are separated based on charge and size. SDS-PAGE - correct answer A polyacrylamide gel electrophoresis method for proteins using DENATURING conditions. Sodium Dodecyl Sulfate denatures the proteins and gives the proteins a uniform charge. This allows them to be separated solely on mass, t...
