英文名：Spectra? Multicolor Low Range Protein Ladder

包裝規格：250ul/支

描述：Thermo Scientific Spectra Multicolor Low Range Protein Ladder is a mixture of six proteins and synthetic peptides (1.7 to 40kDa) for use as size standards for peptides and small proteins in gel electrophoresis and Western blotting.

Features of Spectra Multicolor Low Range Protein Ladder:

? Size range—six proteins and peptides spanning 1.7 to 40kDa
? Multicolor—three different colors for unambiguous band-size assignment
? Ready-to-use—supplied in a loading buffer for direct loading on gels; no need to boil
? Sharp bands—color-coded bands of similar intensity for easy visualization
? Quality tested—each lot evaluated by SDS-PAGE and Western blotting
? Membrane-compatible—colored bands transfer to membranes for Western blotting

Includes:
? Dye-stained proteins in 62.5 mM Tris-H3PO4 (pH 7.5 at 25°C), 1 mM EDTA, 2% SDS, 10 mM DTT, 1 mM NaN3 and 33% glycerol.

Applications:
? Monitoring of protein migration during SDS-PAGE
? Verifying Western transfer efficiency
? Approximate sizing of proteins on SDS-polyacrylamide gels and Western blots
? Locating a protein of interest for excision from an unstained preparative gel

This prestained protein MW marker is designed for monitoring the progress of SDS-
