Biotin-PEG8-DBCO is a PEG linker containing a DBCO moiety and a biotin group. The DBCO groups is commonly used for Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds in aqueous media. The terminal biotinylation can react with amine molecules in the presence of activator EDC or HATU. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The 50 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. This Ladder contains ten discrete fragments ranging from 50 bp to 500 bp with a higher intensity reference band at 250 bp. This Ladder is ideal for quick sizing of PCR products
Contents
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

50 bp DNA Ladder (Cat# 13525) – 100 loads
Ladder Properties:
• Ten discrete bands, ranging from 50 bp to 500 bp
• Higher intensity band at 250 bp for easy reference
| Fragment | Size (bp) | Mass (ng) |
| 1 | 500 | 79 |
| 2 | 450 | 67 |
| 3 | 400 | 59 |
| 4 | 350 | 55 |
| 5 | 300 | 49 |
| 6 | 250 | 76 |
| 7 | 200 | 33 |
| 8 | 150 | 22 |
| 9 | 100 | 31 |
| 10 | 50 | 29 |
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.
