IgG Fraction (EGF) Antibody – Polyclonal

Immunocytochemistry: This antiserum has been found to stain cells known to express human EGF at a dilution of 1:800.

Western Blot: Western immunoblots have been successful at a dilution of 1:1600.

Western Blot Protocol: 1. After SDS-PAGE on 15% gels and electrophoretic transfer to PVDF membrane. block the membrane overnight with 4% normal goat serum in TBS/Tween-20 buffer.
2. Wash x 2 with TBS/Tween-20.
3. Apply the rabbit polyclonal antibody after dilution to at least 1:1600 (Note: higher dilutions may be needed). Use 2% normal goat serum in TBS/Tween-20 as buffer for the primary antibody. Let the primary antibody bind for 2-4 hours.
4. Wash x 3 with TBS/Tween-20.
5. Apply affinity purified HRP-goat anti-rabbit IgG antiserum diluted 1:2500 (dilution may vary depending upon supplier) in 2% normal goat serum in TBS/Tween-20. Incubate 1-2 hours. Note: greater sensitivity may be achieved using ABC techniques.
6. Wash x 4 for 5 minute per wash cycle with TBS/Tween-20.
7. Develop color using the enhanced DAB reaction
