Description
The PM1700 ExcelBand™ All Blue Broad Range Protein Marker is a blue protein standard with 12 pre-stained proteins covering a wide range of molecular weights from 10 to 240 kDa in Tris-Glycine buffer (9 to 235 kDa in Bis-Tris (MOPS) buffer and Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore, and two reference bands (at 25 kDa and 72 kDa, respectively) are enhanced in intensity when separated on SDS-PAGE (Tris-Glycine buffer).
The PM1700 ExcelBand™ All Blue Broad Range Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.
Features
Contents
Approximately 0.1~0.5 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25°C), 2% SDS, 0.2 mM DTT, 3.6 M urea, and 15% (v/v) glycerol).
Quality Control
Under suggested conditions, PM1700 ExcelBand™ All Blue Broad Range Protein Marker resolves 12 major bands in SDS-PAGE (Tris-Glycine buffer, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane.
Storage
4°C for 3 months
-20°C for long term storage
Description
The ExcelDye™ 6× DNA Loading Dye (Tri-Color) is pre-mixed buffer for tracking the DNA sample during the electrophoresis on agarose or polyacrylamide gels. It contains three dyes (Xylene cyanol FF, Bromophenol blue, Orange G) for tracking the DNA migration. The Xylene cyanol FF, Bromophenol blue and Orange G migrate at approximately 800 bp, 150 bp and 30 bp on a standard 2% TAE agarose gel respectively (4,000 bp, 500 bp and 50 bp on 1% TAE agarose gel respectively). The included glycerol keeps the DNA at the bottom of the well and the presence of EDTA chelates divalent metal ions to prevent the process of metal-dependent nuclease.

The Norgen PCR Ranger 100 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our PCR Ranger DNA Ladder contains eleven discrete fragments ranging from 50 bp to 1000 bp with a higher intensity reference band at 500 bp. This Ladder is ideal for assessment of a range of PCR product sizes.
Contents
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

Recommended Use:
Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage:
Stable at room temperature. For longer term storage, -20°C is recommended.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
