1. Fully Customized Protein Ladders
Design your own prestained or unstained protein ladder tailored precisely to your experimental needs. Specify your preferred number of protein bands, molecular weight range, and color selections to create a ladder that fits your unique requirements.
2. Flexible Minimum Order Volumes
We accommodate a broad range of production scales with minimum order volumes starting from 500 ml up to 10 liters. Choose between 3 to 12 protein bands and select from 1 to 3 staining colors to suit your laboratory workflow and budget.
3. Scientifically Optimized Protein Selection
Our proteins are carefully categorized by molecular weight into ten distinct regions, ranging from high to low molecular weights. We recommend selecting one protein from each region to ensure an even molecular weight distribution and clear, well-separated bands on your gel for precise size estimation.
