Agarose

Supplier: VWR

Fine white powder.

Supplier: VWR

A low-melting agarose that melts between 62 to 68 °C and remains liquid for several hours at 37 °C. Ideal for purification of macromolecules from agarose slices and for in-gel enzymatic manipulations.

Agarose is useful in separation of nucleic acids electrophoretically because agarose gels have larger pore sizes than cross linked acrylamide gels at low concentrations and in chromatographic separations by either beading the agarose or cross-linking it. Agarose gels are also used in immunoelectrophoresis (IEP) and double-diffusion Ouchterlony plates to demonstrate antibody-antigen reactions.

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.

Agarose for electrophoresis low electroendosmosis (EEO) (Mr <= 0.10)

Supplier: MP Biomedicals

Agarose is a purified linear galactan hydrocolloid isolated from agar or agar-bearing marine algae.
Agarose is useful in separation of nucleic acids electrophoretically because agarose gels have larger pore sizes than cross linked acrylamide gels at low concentrations and in chromatographic separations by either beading the agarose or cross-linking it. Agarose gels are also used in immunoelectrophoresis (IEP) and double-diffusion Ouchterlony plates to demonstrate antibody-antigen reactions. Agarose was used to prepare 0.5% agarose gel for Southern blot analysis of the DNA extracted from primate muscles.
The following is a list of properties associated with our agaroses: Sulfate content - used as an indicator of purity, since sulfate is the major ionic group present. Gel strength - the force that must be applied to a gel to cause it to fracture. Gel point - the temperature at which an aqueous agarose solution forms a gel as it cools. Agarose solutions exhibit hysteresis in the liquid-to-gel transition - that is, their gel point is not the same as their melting temperature. Electroendosmosis (EEO) - a movement of liquid through the gel. Anionic groups in an agarose gel are affixed to the matrix and cannot move, but dissociable counter cations can migrate toward the cathode in the matrix, giving rise to EEO. Since electrophoretic movement of biopolymers is usually toward the anode, EEO can disrupt separations because of internal convection.

Agarose LM, low melting for recovery of samples after separation

Supplier: MP Biomedicals

Agarose is a purified linear galactan hydrocolloid isolated from agar or agar-bearing marine algae. It is a linear polymer consisting of alternating D-galactose and 3,6-anhydro-L-galactose units. It is specially prepared to allow recovery of active DNA after separation, with minimal inhibition of restriction and ligation enzymes. Suitable for both analytical and preparative electrophoresis procedures.
