BIOLADDER® Dual Color Prestained Protein marker

500 ul, 2.6mg/ml





文字方塊: 4-20 % SDS - PAEG





Ready-to-use Premix in 500 μl gel loading buffer, Dual ColorApplicable Applications:


Prestained Protein Marker II, middle molecular weight

range, resolved to 8 sharp bands when analyzed by

SDS-PAGE, is a mixture of purified proteins covalently

coupled to blue and orange chromophore. It consists of 8

proteins ranging in apparent molecular weight from

approximately 15 kD to 150 kD. Prestained Protein Marker

II is supplied in gel loading buffer and ready-to-use.


Molecular weight estimation

Monitoring protein transfer efficiency onto membranes

during Western blotting

Monitoring electrophoresis separation

Recommended Usage:

Thaw the Marker either at room temperature or 37-40for 1 minute if any solids

was precipitated at -20.

After a quick spin, load directly onto a gel:

For blotting: load 3 μl for mini-gels and 6 μl for full length gels.

For visualizing during electrophoresis: load 5 μl for mini-gels and 10 μl for full

length gels.

Quality Control:

Tested in SDS-polyacrylamide gel electrophoresis and Western blotting
