Pre-stained Protein Ladder

Pre-stained Protein Ladder is an essential reference reagent in protein electrophoresis experiments. It enables real-time monitoring of the electrophoretic process, rapid estimation of target protein molecular weight, verification of transfer efficiency, and improved experimental reproducibility.

X-Biotech Pre-stained Protein Ladder delivers outstanding performance across four key areas:More >>

Precision & Buffer Adaptability: Provides accurate molecular weights across all common buffer systems. Apparent MWs closely mirror unstained ladders for reliable sizing under any condition.

Superior Band Quality: Produces sharp, intense, and compact  bands with exceptional clarity. Band morphology remains highly consistent before and after Coomassie Brilliant Blue staining.

Reliable Batch-to-Batch Consistency: Rigorous quality control guarantees less than 1% lot-to-lot variation.

Outstanding Cost Performance: Premium quality at a highly competitive price, with no compromise on any specification.
