PRODUCT OVERVIEW
Product type: Protein ladders. Indexed format and requirements: Prestained protein ladders; Broad-range protein ladders.
Workflow context: Protein ladders provide reference bands for protein separation workflows. Compare the documented size range, staining format and compatibility with the gel and detection method.
Prestained protein markers must be assessed in the documented gel and detection system. Compare the supplied band pattern and the reference information provided for that format.
Before choosing an alternative, compare band pattern, useful size range, loading formulation and detection method. Products in the same category are comparison candidates, not validated interchangeable replacements.
Manufacturer catalog numbers and packs: P7719S (150 gel lanes); P7719L (750 gel lanes).
