SeaKem® LE Agarose

SeaKem® LE Agarose

Catalog #: 50000

SeaKem® LE Agarose, 125 g, ideal for routine analysis of nucleic acids by gel electrophoresis and blotting.


 287.00 CHF

Product Overview

SeaKem® LE Agarose was the first and is still the world’s most trusted agarose for nucleic acid electrophoresis. Ideal for routine analysis of nucleic acids by gel electrophoresis and blotting, each SeaKem® LE Gel sharply resolves DNA and provides consistent resolution from lot-to-lot. This molecular biology grade agarose has no detectable DNase or RNase activity and forms strong gels with low background upon ethidium bromide, SYBR® Green, or GelStarTM Staining. Due to its low EEO, DNA will have a high electrophoretic mobility. SeaKem® LE Agarose is also recommended for protein gel electrophoresis in applications such as Ouchterlony and radial immunodiffusion (RID).


Analytical Specifications

Gelling temperature (1.5%)  36°C ±1.5°C
