PR1MA™ Rapid Coomassie Stain

Chemical Formula: C5H10O5

Solubility: Water

Storage Temp: Room Temperature

This unique Coomassie Blue based formulation features a special dye that is absorbed by protein bands instead of the gel matrix. This eliminates the need for destaining and offers enhanced sensitivity and sharper resolution of bands. Protein bands can be detected within 10 minutes. Maximum intensification may require incubation up to 40 minutes. Offers greater convenience and sensitivity than conventional stains. Compatible with silver staining. Rapid Coomassie stain uses a simple two-step procedure. Stain is designed to detect as little as 7.9ng of protein within one hour of electrophoresis.

Supplied as 20X concentrated solution.

Shelf life is approximately 18 months at room temperature.

Shipping Weight: 0.3 lbs
