![]() The protein standard 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. These standards can be used for fluorescent blot detection at red wavelengths (635 nm laser or red LED). HiMark Unstained High Molecular Weight (HMW) Protein Standard contains nine proteins in the range of 40500 kDa designed for analysis of high molecular weight proteins. Approximately 0.10.4 mg/ml of each protein in the buffer (20 mM Tris. The protein ladder is supplied in a ready-to-use format for direct loading onto gels no need to heat, reduce, or add sample. Precision Plus Protein All Blue Standards are a mixture of ten blue-stained recombinant proteins (10–250 kD), including three reference bands (25, 50, and 75 kD). The PL00002 Broad Range Prestained Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (nitrocellulose, PVDF, or nylon) and for estimating the size of proteins. 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. These unstained protein standards include three high-intensity reference bands (25, 50, and 75 kD). ![]() Place this handy selection guide magnet on your refrigerator or lab bench to eliminate the guesswork and make protein standard selection simple. The Thermo ScientificTM PageRulerTM Unstained Protein Ladder consists of a unstained mixture of 14 recombinant, highly purified proteins ranging from 10 kDa to 200 kDa. ![]()
