Methyltetrazine-PEG7-DBCO

Overview

• Ready-to-use
• Quantitative
• Highly Stable
• Precise
• 10 discrete bands from 50 bp to 500 bp
• Higher intensity reference band at 250 bp

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.
