The third step entails gel electrophoresis. I order to separate the different proteins from each other, te lysades became loaded on SDS polyacrylamide gel. SS as a component of the gel allowed for neutralization of the proteins thereby making their separations entirely based on molecular weight (Kontermann 2002, p The separation became performed by use of constant voltage. I order to visualize, te use of a dye called bromophenol blue became used (Rosenberg 2005, pThe fourth step in western blot analysis involved blotting. I here, botting refers to transfer of the given proteins to the membrane from the gel by use of electric power plus nitrocellulose.
Te membrane pores of nitrocellulose permanently accommodate the given proteins transfer from the gel (Rosenberg 2005, pMore over, te fifth step in western blotting analysis involves blocking. Tis process involves filling with empty pores of the given nitrocellulose membrane with some certain proteins that will not be recognized by antibodies used commonly in the experiment (BSCL bovine serum albumin) (Rosenberg 2005, pThe sixth step entails incubation with primary antibody. I here, become incubated in a solution containing primary antibody that got the capability of recognizing target proteins.
Nrmally, te primary antibody often becomes dissolved in the given buffer used for deblocking. Te primary antibody often permanently binds to the given target protein (Rosenberg 2005, pThe seventh step in western blot analysis entails application of the secondary antibody. Hre, asecondary antibody becomes applied after primary antibody incubation. Te secondary antibody often goes and binds to the primary antibody forming a protein-antibody-antibody sand witch. Nrmally, te secondary antibody becomes labeled with dye the purpose of visibility (Rosenberg 2005, pTherefore, te eighth procedure in western blot analysis involves visualization.
Hre, te visualization of the target protein and antibodies become possible. Tis could be achieved by the help of fluorescent scanning. Uually, te secondary antibody contain peroxidase enzyme that often converts luminal substrate to give a light releasing substrate. I hence becomes the light which becomes detected as a spot on the film (Rosenberg 2005, pIn the ninth step, i western blot. ..
