Overview

Unstained Standards
Unstained Standards

Precision Plus Protein unstained standards on a gel. These standards have been engineered to contain the unique Strep-tag affinity peptide, which allows detection and molecular weight determination on western blots.

Using Precision Plus Protein™ Standard Plugs

Step 1
Break and twist off one end of the plastic plug casing.

Step 2
Break off an individual plastic plug from the casing by placing pressure on the flat side to break the junction.

Step 3
Complete the break by twisting off the individual plastic plug casing.

Step 4
Snap off the attached spatula.

Step 5
Use the spatula to push the plug out of the plastic casing.

Step 6
Use the spatula to slide the plug outward and on to the top plate of your gel.

Step 7
Slide the plug all the way down the bottom of the well next to IPG strip. Then add an agarose overlay.

Precision Plus Protein standard plugs allow easy, quick, and clean loading of molecular weight standards on any gel. The plugs can be used on vertical 2–D gels with no reference well. Precision Plus Protein unstained standards are cast in 1 mm thick agarose plugs for easy storage, handling, and loading. Load concentrations have been optimized for SYPRO Ruby, Silver Stain Plus, and Bio-Safe Coomassie Blue staining.

Some features and benefits of the plugs are:

  • Precast for ease of use — just snap, twist, and load the plug onto a gel
  • Absolute molecular weight accuracy, confirmed by mass spectrometry
  • Ideal ten-band range from 10 kD to 250 kD, with 3 high-intensity reference bands (25 kD, 50 kD, and 75 kD) for instant gel orientation
  • Molecular weights that never change, so band sizes are easy to remember
  • High r2 value, >0.995, allowing accurate molecular weight determination
  • Known concentration of protein in each band, allowing quantitation capability
  • Strep-tag amino acid sequence for detection and molecular weight determination on western blots
