20bp Ladder

20bp Ladder is an ideal DNA Ladder for determining the size of double-stranded DNA (dsDNA) from 60 to 300 base pairs (bp) in high percentage agarose or non-denaturing polyacrylamide gels. The ladder consists of 13 linear dsDNA fragments. It is a 20 bp step ladder, especially useful for determining 20 bp differences between DNA fragments. The 100bp and 200bp fragments are present at increased intensity to allow easy identification. All fragments are precisely quantified and mixed during the production. This ladder is pre-mixed with loading dye and is ready to use.

Application
agarose gel electrophoresis, AGE
Non-denaturing polyacrylamide gel electrophoresis (PAGE)
pulsed field gel electrophoresis, PFGE

Features
Clear and bright bands for accurate molecular weight determination
Stable quality allows for use at room temperature
Multiple ranges available with 23 classic series and 18 LD series options to suit different gel dyes
Two Marker series are suitable for different types of gel dyes, and the strips are not easily deformed
