The BLUltra Prestained Protein Ladder is a three-color protein standard with 10 pre-stained proteins covering a wide range of molecular weights from 6.5 to 270 kDa. Proteins are covalently coupled with a blue chromophore except for three reference bands (two orange bands at 30 kDa and 270 kDa and one green band at 52 kDa) when separated on SDS-PAGE (Tris-glycine buffer).  The BLUltra Prestained Protein Ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis and verifying Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. The ladder is supplied in the gel loading buffer and is ready to use.

 

Nowadays, more and more researchers are studying the high molecular weight proteins, meaning they may need high-resolution prestained protein standards, especially with high molecular weights. That's why we're pleased with launching the color-enhanced BLUltra prestained protein standards.

As you may see the comparison data shown above, BLUltra shows a better resolution than the BLUeye & BlueRAY for the protein bands from 95 kDa to 270 kDa.

 

One-Vial-Fits-All: New broad-range protein ladder from 6.5kDa to 270kDa.
Higher Added Value: Tri-colors and 10 bands with premium quality.

Better performance for high molecular weight proteins.
Clear separation map from 6.5 kDa to 270 kDa in the Tris-Glycine system.
Enhanced transfer, wash, and stripping durabilities.

 

• 3 μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively.
• 2.5 μl per well for general Western transferring.

Storage Buffer : 

62.5 mM Tris-H3PO4 (pH 7.5 at 25 °C), 1 mM EDTA, 2% SDS, 10 mM DTT, 1 mM NaN3, 33% glycerol.

Quality Control : 
Under suggested conditions, BLUltra Prestained Protein Ladder resolves 10 major bands in 4-12% Bis-Tris Gel(MES buffer) and after Western blotting to the nitrocellulose membrane.


Stable for up to 3 months at 4°C.
Stable for up to 2 weeks at 25°C.
Storage: For 
long-term storage, store at -20°C.

Note: The apparent molecular weight (kDa) of each protein has been determined by calibration against unstained protein standards; supplemental data should be considered for more accurate adjustment in different electrophoresis conditions.
All products are for research use only.


Caution: Not intended for human or animal diagnostic or therapeutic uses.
