Thermo Scientific™ PageRuler™ Unstained Low Range Protein Ladder
Description
Thermo Scientific™ PageRuler Unstained Low Range Protein Ladder is a mixture of eight (8) purified proteins and peptides (3.4 to 100kDa) for use as size standards in peptide and small protein gel electrophoresis.
Thermo Scientific PageRuler Unstained Low Range Protein Ladder is a mixture of eight purified proteins and peptides (3.4 to 100 kDa) for use as size standards in peptide and small-protein gel electrophoresis. The protein ladder is supplied in a ready-to-use format for direct loading onto gels; no need to heat, reduce, or add sample buffer prior to use.
Product features
- Reference bands—25 kDa band is stronger than the others for easy orientation
- Tagged—the ladder proteins (except for the 5 and 3.4 kDa peptides) contains an integral Strep-tag™ II sequence and can be detected on western blots using Strep-Tactin™ conjugates
Applications
- Accurate protein sizing on SDS-polyacrylamide gels and western blots
