The Norgen PCRSizer 100 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our PCRSizer contains ten discrete fragments ranging from 100 bp to 1000 bp in 100 bp increments with a higher intensity reference band at 500 bp. This Ladder is ideal for PCR product size confirmation.
Contents:
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

PCR Sizer 100 bp DNA Ladder (Cat# 11400) – 100 loads
Ladder Properties:
• Ten discrete bands, ranging from 100 bp to 1,000 bp
• Higher intensity band at 500 bp for easy reference
| Fragment | Size (bp) | Mass (ng) |
| 1 | 1000 | 78 |
| 2 | 900 | 70 |
| 3 | 800 | 62 |
| 4 | 700 | 55 |
| 5 | 600 | 47 |
| 6 | 500 | 78 |
| 7 | 400 | 31 |
| 8 | 300 | 24 |
| 9 | 200 | 31 |
| 10 | 100 | 24 |
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.
endo-BCN-PEG8-PFP ester is a PEG linker featuring a BCN group and a PFP ester. BCN is a click chemistry handle used to react with azides on target molecules while the PFP is a good leaving group which is readily displaced by amines to form amides.
