Product Information

The PL00001 Regular Range Protein Marker is a ready to use three-color protein standard with 10 prestained proteins covering a wide range of molecular weights from 10 to 180 kDa. The PL00001 Prestained 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 estimating the size of proteins.

Detection Method Colorimetric

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 Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol).
Storage Store product at 4 C for up to 12 weeks. For longer storage, aliquot and store at -20 C for up to 1 year.
Instructions The protein ladder comes ready to use in gel loading buffer. After thawing and mixing, load approximately 3 -5 μL of protein marker per lane. Do NOT heat, dilute, or add reducing agents before loading.
