The Opentrons 24-well Aluminum Block can be placed directly on the OT-2/Opentrons Flex deck or on the Opentrons Temperature Module. This block acts as a 24 position rack to keep 2mL tubes, 1.5mL tubes, and the NEST 0.5mL tubes at constant temperature. The aluminum block holds temperatures between 4°C and 95°C when used with the Opentrons Temperature Module (GEN2).

The Norgen LowRanger 100 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our LowRanger contains eleven discrete fragments ranging from 100 bp to 2000 bp in 100 bp increments with a higher intensity reference band at 500 bp. This Ladder is ideal for fast running times and accurate visual determination.
Contents:
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

LowRanger 100bp DNA Ladder (Cat# 11500) – 100 loads
Ladder Properties:
• Eleven discrete bands, ranging from 100 bp to 2000 bp
• Higher intensity band at 500 bp for easy reference.
| Fragment | Size (bp) | Mass (ng) |
| 1 | 2000 | 110 |
| 2 | 1500 | 83 |
| 3 | 1000 | 55 |
| 4 | 800 | 44 |
| 5 | 700 | 39 |
| 6 | 600 | 33 |
| 7 | 500 | 55 |
| 8 | 400 | 22 |
| 9 | 300 | 17 |
| 10 | 200 | 22 |
| 11 | 100 | 22 |
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.
