1. HOW DID OUR ANTIBODY PERFORM? CUSTOMER REVIEW: HA-tag Polyclonal Antibody (STJ90107)
2. WHAT WAS USED? Antibody: STJ90107. HA-tag Polyclonal Antibody Method for validation: Western Blot Materials for validation: HeLa cell line, Jurkat cell line Treatment of materials: When cells were cultured to 70%-80% plating density, lysis buffer with protease inhibitors (Sigma) and equal volume of 2X loading buffer were added for 10 min water bath at 100?C. Result of validation: Target band was found in the material cell lines.
3. WHAT WAS THE PROTOCOL? Primary antibody: Product Catalog No: STJ90107. HA-tag Polyclonal Antibody. 100ul Provider: St John’s Laboratory Dilution ratio: 1:1000 Secondary antibody: HRP goat anti-rabbit (provided by BPI) Reference antibody: Actin (provided by BPI)
4. WHAT WAS THE PROTOCOL? Gel electrophoresis: 10% polyacrylamide gel, constant voltage 160 V, 60 min. Transfer: 0.45 nm PVDF membrane, 1 piece of gel (wet transfer), constant voltage 100 V 60 min. Blocking: 1X TBST with 5% skimmed milk powder for 2 hr. Primary antibody probing: primary antibody was added to the solution of 1X TBST with 5% skimmed milk powder, 4?C for overnight. Membrane wash: 1X TBST wash for 3 times. Secondary antibody probing: secondary antibody was added to the solution of 1X TBST with 5% skimmed milk powder with 1:10000 dilution ratio, for 1.5 hr. Membrane wash: 1X TBST wash for 3 times. Visualization: ECL visualization for 5 min (the visualization time was determined by actual result. It was ensured that the visualization time was identical for the same antigen).
