Western Blotting and Antibodies

Western blotting employs antibodies to pinpoint specific proteins of interest in complex protein mixtures such as cell extracts. Because of its accuracy, western blotting is used as the confirmatory diagnostic test for HIV and mad cow disease (bovine spongiform encephalopathy). Western blotting is used extensively in research to determine the presence of specific proteins, to quantify their expression levels, and to determine whether they have undergone genetic or posttranslational modifications. This surefire method categorically identifies proteins of interest based on two distinguishing features: molecular mass and antibody binding specificity.

When foreign invaders are detected, animal immune systems naturally generate antibodies and tag them for destruction. The ability of antibodies to act like magic bullets and target viral, bacterial, and allergenic antigens in the body also makes them ideal tools in the hunt for specific molecules in bioscience research and diagnostic tests.

Western blot of protein profiler gel reveals precise location of myosin light chain proteins.

Description

The Comparative Proteomics Kit II: Western Blot Module is the second part of a two-part laboratory. In the first part of this laboratory (Comparative Proteomics Kit I: Protein Profiler Module), students use sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) to generate protein profiles and to visualize the unique array of proteins comprising muscle tissues from different fish. In this second part of the laboratory, students apply western blotting techniques to their polyacrylamide gel results to specifically identify myosin light chain from the hundreds of proteins that comprise the muscle cell extracts of closely and distantly related species of fish.

Features and Benefits

  • Applies immunology
  • Teaches students to use antibodies as detection tools
  • Serves as a laboratory extension for the Comparative Proteomics I Kit: Protein Profiler Module

How It Works

The protocol involves transferring the protein bands from polyacrylamide gels to a membrane and then using an anti-myosin light chain antibody to precisely identify which protein in each species' profile is myosin light chain. Using Internet-based bioinformatics databases, students can compare their experimentally determined results to actual protein sequence data derived from DNA and RNA sequences and consider whether variations in myosin among species are due to "genetic" or "epigenetic" factors.
