Precision Plus Protein™ Standards for protein electrophoresis offer unsurpassed band sharpness, accurate MW determination, lot-to-lot consistency, and excellent blotting results. These standards contain ten highly purified recombinant proteins with molecular masses from 10 to 250 kD. These unstained protein standards include three high-intensity reference bands (25, 50, and 75 kD).

Precision Plus Protein Unstained Standards contain the unique Strep-tag affinity peptide, which allows detection and molecular weight determination on western blots. These standards offer absolute molecular weight accuracy confirmed by mass spectrometry, with a known amount of protein in each band to allow approximation of protein concentration in your sample. These protein standards are compatible with Laemmli and neutral pH buffer systems and can be used for accurate molecular weight determination on gels and blots.

Precision Plus Protein Unstained Standards are also an excellent choice for use with stain-free gels and the
Gel Doc™ EZ imaging system.

All Precision Plus Protein Standards generate a standard curve with r2 values >0.99, demonstrating a strong linear relationship between the proteins' log molecular weight and relative migration distance on a gel.
