Western blotting is a powerful technique that allows you to positively detect your proteins, estimate quantities, and determine their molecular weights starting from a mixture of proteins extracted from cells or tissues.
Stain-Free Western Blotting
Stain-free western blotting allows you to quickly check electrophoresis and blot transfer quality and obtain truly quantitative western blotting results, updating traditional blotting techniques with innovative tools.
Faster Results. Better Data.
Western Blotting Transfer Systems
The Trans-Blot Turbo System enables fast, efficient, and reproducible transfer of proteins up to 400 kD. Preassembled Trans-Blot Turbo Transfer Packs are optimized for superior blot transfer.
- Fast transfer, in as little as 3 min
- Highest efficiency transfer
- High throughput — 4 mini gels or 2 midi gels per run
- Recommended for Stain-Free Western Blotting
Semi-Dry and Rapid Blotting Systems
Wet/Tank Blotting Systems
- Mini Trans-Blot Cell — for 2 mini gels
