• Blue Loading Buffer Pack

1. Recommended load for SDS-PAGE Analysis is 15 μl, while 6 μl is recommended for Western blot analysis.
2. Apparent molecular weights of every band are determined on Invitrogen Novex 10-20% Tris-glycine SDS PAGE gels using NEB's Protein Ladder (NEB #P7703)..

1. Is the ColorPlus Prestained Protein Marker stable at room temperature?
2. After repeated freeze/thaws, I have noticed a fading or speading out of the low molecular weight bands in the ColorPlus Prestained Protein Marker. Is there any way to extend the shelf-life of this product?
3. Why do the apparent molecular weight values for the prestained protein markers appear to be different in different gel types?
