Western Blot
Lab
Western Blot reagents and equipment
• Mini Trans-Blot Apparatus : Passes electric current horizontally through gel – forcing negatively charged proteins to migrate out of gel onto nitrocellulose membrane
• Nitrocellulose membranes: Proteins bind to positive charge
- Durable membrane can undergo multiple washing and incubation steps
- White background to visualize color development of proteins
Western Blot reagents and equipment
• Blotting paper – supports gel and nitrocellulose- Protects filter pads during assembly and
electrophoresis- Facilitates uniform flow of buffer and current
through gel- 100% cotton fiber – does not contain any
additives that may interfere with blotting process
Western Blot reagents and equipment
• Filter pads: Press the gel and nitrocellulose tightly and uniformly
- Eliminate bubbles – allows transfer of proteins out of gel onto the membrane
- Should be cleaned in distilled water before use
Western Blot reagents and equipment
• Blotting buffer: Should be diluted to 1X• Blocker: 5% nonfat dried milk powder in
phosphate buffered saline (PBS) and 0.025% tween 20
• Surface area unoccupied by proteins- blocked by incubating milk solution – before incubation with primary antibody
Western Blot reagents and equipment
• Primary antibody: recognizes or bind protein under study
- Injecting chicken myosin protein into mice• Secondary antibody: binds to primary
antibody- Polyclonal goat anti-mouse antibody
conjugated to horseradish peroxidase enzyme- Injecting goats with primary mouse antibodies
