Thermo Scientific™ PageRuler™ Unstained Protein Ladder
A mixture of seven native proteins (14.4 to 116kDa) for use as size standards in protein electrophoresis (SDS-PAGE).
Brand: Thermo Scientific™ 26614
UNSPSC : 41105337
Code : PN
Additional Details : Weight : 1.36080kg
DescriptionEach protein in the ladder contains an integral Strep-tag™ II Sequence which can be detected directly on Western blots using a Strep-Tactin™ Conjugates or an antibody against Strep-tag™ II Sequence. The Ladder produces sharp bands on SDS-polyacrylamide gel following staining of the gel with Thermo Scientific Pierce Gel Stains or other coomassie dye or silver stains. The 50kDa protein band is of greater intensity and serves as a reference band.
Size range – 14 proteins spanning 10 to 200kDa
Ready-to-use – supplied in a loading buffer for direct loading on gels
Sharp bands – excellent accuracy for detection in with coomassie or silver stains
Reference band – 50kDa band is has greater intensity for easy orientation
Tagged – each protein in the ladder contains an integral Strep-tag™ II Sequence
Quality tested – each lot evaluated by SDS-PAGE and Western blotting
Proteins (0.02 to 0.05mg/mL of each) in 62.5mM Tris-H3PO4 (pH 7.5 at 25°C), 1mM EDTA, 2% SDS, 100mM DTT, 1mM NaN3, 0.01% bromophenol blue and 33% glycerol.
