Description 

The PM5100 3-color Pre-Stained Protein Ladder High Range is a ready-to-use three-color protein standard with 14 pre-stained proteins covering a wide range of molecular weights from 10 to 245 kDa in Tris-Glycine Buffer (9 to 235 kDa in Bis-Tris (MOPS) buffer and 10 to 235 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with different chromophores for easy identification of bands, with three reference proteins carrying enhanced intensity corresponding to a blue band at 20 kDa, green at 40 kDa, and red at 75 kDa, respectively, as separated on SDS-PAGE (Tris-Glycine buffer). The PM5100 3-color Pre-Stained Protein Ladder High Range 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

• Ready-to-use — Premixed with a loading buffer for direct loading, no need to boil.
• Three reference bands — 75 kDa (red), 40 kDa (green), and 20 kDa (blue)

Contents

Approximately 0.1~0.4 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, PM5100 ExcelBand™ 3-color Pre-Stained Protein Ladder High Range resolves 14 major bands in SDS-PAGE (Tris-Glycine, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane. 

Storage

4°C for 3 months
-20°C for long term storage

Propargyl-PEG3-CH2CO2H is an PEG linker with an alkyne and carboxylic acid set of functional groups. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry to form a stable triazole linkage. The carboxylic acid can react with primary amines to form stable amide bonds; activator (e.g. EDC, or HATU) is needed.
