Precision Plus Protein™ Standard Plugs

Precision Plus Protein™ Standard Plugs


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.

Second dimension SDS-PAGE gel run with a mouse brain sample, Precision Plus Standards Plugs, and stained with Bio-Safe™ coomassie G-250 stain.

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.

Precision Plus Protein™ Standard Plugs

Precision Plus Protein standards packaged in an easy-to-use plug for 2-D electrophoresis.

Precision Plus Protein™ Standard Plug Run on a PROTEAN Plus Gel

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


Precision Plus Protein standard plugs come in easy-to-use snap-off molds in packs of 24 (one application per plug).
