Molecular Weight Markers and Sample Loading Buffer 
A variety of molecular weight markers for use with one- and two-dimensional gels and for various detection methods

MW Marker Selection Guide 
Guide to Thermo Scientific Molecular Weight Markers for protein electrophoresis (SDS-PAGE). 


Lane Marker Sample Buffers 
Ready-to-use 5X SDS-PAGE sample loading buffers with pink lane marker for Western Blots. Reducing and non-reducing forms available. 


LDS Sample Buffer (4X) 
Thermo Scientific LDS Sample Buffer, Non-Reducing (4X), convenient sample buffer for use in SDS-polyacrylamide gel electrophoresis, contains coomassie dye, enabling visualization of the electrophoresis progress. 


Blue Prestained Protein Molecular Weight Marker 
Pierce "BlueRanger" MW Marker consists of individually dried and stabilized mixtures of seven dye-modified proteins spanning the molecular weight range from 18K to 215K. No need to boil - just add water and load. 


3-Color Prestained Protein Molecular Weight Marker 
The Pierce "TriChromRanger" MW Marker consists of individually dried and stabilized mixtures of seven dye-modified proteins spanning the molecular weight range from 16K to 210K. Blue, purple and pink protein bands make identification easy. 


Chemiluminescent Blue MW Marker Mix 
A blue-stained and peroxidase-labeled MW marker mix that produces chemiluminescent signal with SuperSignal Substrates and other HRP-based chemiluminescent substrates. Consists of seven proteins, 18K-220K. 


DyLight Fluorescent Protein MW Markers 
Two dual-channel fluorescent MW marker mixes (9 proteins, 6K-200K MW) to match commonly used yellow/red (DyLight 549/649 and Alexa Fluor 546/555/647) and near-IR (680/800) fluors for in-gel or on-membrane detection. 


2-D Protein Molecular Weight Marker Mix 
A mixture of seven proteins ranging in molecular weight from 17K to 80K and isoelectric point (pI) values from 4.5 to 8.7. The Marker Mix provides a profile of reference landmarks for assessing performance and reproducibility 2-D electrophoresis runs.
