100bp DNA Ladder H3 RTU 
Description 
A unique combination of PCR products and a number of proprietary plasmids digested with appropriate restriction enzymes to yield 12 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. 
The DNA includes fragments ranging from 100-3,000 base pairs. The 500 and 1,500 base pair bands have increased intensity to serve as reference points. 
The approximate mass of DNA in each band is provided (0.54 μg a load) for approximating the mass of DNA in comparably intense samples of similar size.

• 3 μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively• 2~3 μl per well for general Western transfering. 
• Apply more for thicker (>1.5 mm) or larger gel. 

Description 
The BlueRAY Prestained Protein Ladder is a three-color protein standard with 10 pre-stained proteins covering a wide range molecular weights for 10 to 180 kDa. 
Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Tris-glycine buffer). 
The BlueRAY Prestained Protein Ladder is designed for monitoring protein separated during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon , or nitrocellulose) and for approximate sizing of proteins. 
The ladder is supplied in gel loading buffer and is ready to use. Do not heat, dilute, add reducing agent before loading. 

Contents 
Approximately 0.2~0.4 mg/ml of each protein in buffer (20 mM Trisphosphate pH 7.5 at 25°C), 2% SDS, 1 mM 2-Mercaptoethanol, 3.6 M Urea, and 15% (v/v) glycerol). 
Quality Control 
5 μl of BlueRAY Prestained Protein Ladder resolves 10 bands in 4-20% SDS-PAGE (Tris-glycine buffer) and after Western blotting to PVDF membrane. 
Storage 
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

Note: The apparent molecular weight of each protein (kDa) has been determined by calibration against an unstained protein ladder in each electrophoresis condition 
Supplement data should be considered for more accurate adjustment\
