Spectra Multicolor Broad Range Protein Ladder|正品现货
Description
Spectra™ Multicolor Broad Range Protein Ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on PVDF, nylon and nitrocellulose membranes and for approximate sizing of proteins (1-3). It is composed of prestained recombinant prokaryotic proteins.
Spectra™ Multicolor Broad Range Protein Ladder is a 4-color protein standard with 10 prestained recombinant prokaryotic proteins covering a wide range molecular weights from 10 to 260 kDa. Four different chromophores are bound to the proteins producing a brightly colored ladder with an easy-to-remember pattern.
Features
Sharp and stable colors.
Multicolor – four different colors.
Ready to load – no need to boil.
Easy to track on gel.
Excellent western transfer.
Applications
Monitoring protein migration during SDS-polyacrylamide gel electrophoresis.
Monitoring protein transfer onto membranes after Western blotting.
Sizing of proteins on SDS-polyacrylamide gels and Western blots.
Quality Control
Tested in SDS-polyacrylamide gel electrophoresis and Western Blotting.
Storage
Stable at 4°C for up to 3 months. For long term storage, store at -20°C.
Storage Buffer
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. |
