MOLECULAR SIEVES 4-ANGSTROM M139984-250G

Supplier: MP Biomedicals

Agarose High Resolution is an intermediate melting agarose with approximately twice the resolution capability of routine agarose. It is a purified linear galactan hydrocolloid isolated from agar or agar-bearing marine algae. It is ideal for the resolution of small DNA fragments in the range 20 bp to 2000 bp.
Agarose high resolution is an intermediate melting and gelling point agarose which exhibits superior sieving characteristics. It is recommended for analytical gels of DNA fragments under 1000 bp and is ideal for small DNA fragments down to 20 bp can be separated on 6 % gels. It resolves fragments differing in size by only 2 bp. Its use avoids the need for PAGE Southern and Northern transfers can be achieved efficiently from them at concentrations up to 2%. DNA fragments can be purified with high efficiency from this agarose gels up to 4% by using either a purification kit or an electroelution system.

SIEVE MOLECULAR AL-MCM-41 NEW 20G

Supplier: IBI Scientific

Ultra Sieve Agarose is designed for high resolution electrophoresis where resolution of polyacrylamide gels are needed. Ultra Sieve Agarose improves clarity of gels and enhances visualization, even at high concentrations. Ultra Sieve Agarose has low viscosity, therefore high concentration gels can be made with high resolving capacity. The high gel strength, low concentration of 1.0-1.5% can also be made. Using TAE buffer, make a 1.8% gel for 400-1200bp, 3.0% gel for 150-800bp, and 4.5% gel for 15-400bp. To achieve the best resolution, store ultra sieve gels at +4-8°C for 30 minutes prior to use.
