The PiNK Plus Prestained Protein Ladder contains 11 proteins that resolve into sharp, tight bands in the range of 10-175 kilodalton (kDa). The PiNK Plus Prestained Protein Ladder allows you to monitor molecular weight separation during on SDS-polyacrylamide gel electrophoresis (SDS-PAGE), estimate molecular weights of proteins of interest, and evaluate western transfer efficiency.
Approximately 0.2~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate, pH 7.5 at 25°C), 2 % SDS, 1 mM Dithiothreitol, 4.8 M Urea, and 12 % (v/v) Glycerol.
The quality of the PiNK Plus Prestained Protein Ladder is tested on a lot-to-lot basis to ensure consistent product quality.
Stable for up to 2 weeks at 25°C.
Stable for up to 3 months at 4°C.
For long term storage, store at -20°C.
|PiNK Plus Prestained Protein Ladder Protocol|
1. Thaw the ladder either at room temperature or at 37-40°C for a few minutes to dissolve precipitated solids. Do not boil.
2. Mix thoroughly to ensure the solution is homogeneous.
3. Load the following volumes of the ladder on SDS-PAGE gel:
