FastGene® Block & Go serves a blocking solution as well as signal enhancer in Western blot analysis.
It provides blocking and primary and secondary antibody hybridization in one step. Furthermore, it enhances the signal developed with HRP (horseradish peroxidase) or AP (alkaline phosphatase) substrates. FastGene® Block & Go reduces time and labor-intensive Western bot procedure.
Features
- 3 steps in one: blocking of the membrane, primary and secondary antibody in one step
- Enhanced antibody signal: 2-5-fold increase in signal intensity for most protein targets.
- Enhance time-saving: It saves at least 2 hours in the antibody detection process during the Western Blot, with only one hour needed.
- Effective with any ECL: After the antibody detection process, the signal can be developed with both HRP (horseradish peroxidase) and AP (alkaline phosphatase) substrates.
- Less hands-on steps: No 3 wash steps are required, meaning no need to transfer the membrane in&out of the container.
- Compatible with PVDF & NC membrane: Regardless of the pore size, ‘Block & Go’ minimizes the background from non-specific protein binding by antibodies.
- Protein free: Reduces overall background and minimizes non-specific signals often seen with ECL detection.
Time saving
By combining 3 steps in one step (blocking + primary antibody + secondary antibody), the procedure can be reduced about 1 h (2-step procedure) or even 2.5 h (1-step procedure) compared to conventional protocol using milk or BSA.
Enhanced signal intensity
Detection sensitivity can be enhanced so that proteins from 0.5 µg lysate can be detected.
