The FastRunner DNA Ladder is prepared to ensure quality and batch-to-batch consistency. This Ladder contains eight discrete fragments ranging from 50 bp to 2000 bp with a higher intensity reference band at 500 bp. This Ladder is ideal for quick sizing of PCR products and restriction digests.
Contents
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

FastRunner DNA Ladder (Cat# 12800) – 100 loads
Ladder Properties:
• Eight discrete bands, ranging from 50 bp to 2000 bp
• Higher intensity band at 500 bp for easy reference
| Fragment | Size (bp) | Mass (ng) |
| 1 | 2000 | 104 |
| 2 | 1500 | 88 |
| 3 | 1000 | 68 |
| 4 | 750 | 59 |
| 5 | 500 | 93 |
| 6 | 300 | 28 |
| 7 | 150 | 35 |
| 8 | 50 | 25 |
Recommended Use:
Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage:
Stable at room temperature. For longer term storage, -20°C is recommended.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
Description
Q-PAGE™ Bis-Tris Precast Gel is a high-performance and easy to use precast polyacrylamide gel for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows Q-PAGE™ Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional Laemmli Tris-HCl gels.
Q-PAGE™ Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (8% and 12%) concentrations of polyacrylamide in 12-and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP2XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP3XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.
Key Features
Storage and stability
Store Q-PAGE™ Precast Gels at 4°C for periods up to 12 months.
Do not freeze Q-PAGE™ Precast Gels Remove tape and comb before electrophoresis.
Keep Q-PAGE™ Precast Gels flat during storage.
