Collection: Protein Ladders

Protein ladders are molecular weight markers and protein size markers consisting of a set of proteins with known molecular weights that are used as reference standards in protein electrophoresis experiments. These ladders are critical in estimating the molecular weights of unknown proteins, verifying the separation of proteins, and assessing the performance of the electrophoresis apparatus. The key differentiating characteristics of protein ladders include:

1. Diverse molecular weights

2. Stable formulations

3. Visible bands

4. Pre-stained or unstained
