MetaPhor®
Agarose
High resolution agarose
Introduction
MetaPhor agarose is a high resolution agarose that challenges polyacrylamide.
MetaPhor agarose is an intermediate melting temperature (75° C) agarose
with twice the resolution capabilities of the finest-sieving agarose products.
Using submarine gel electrophoresis, you can resolve PCR products and
small DNA
fragments that differ in size by 2%.
Analytical Specifications
Gelling temperature (3%) = 35° C
Melting temperature (3%) = 75° C
Gel strength (3%) = 300 g/cm²
Applications
• High resolution separation of 20-800 bp DNA fragments
• Recovery of fragments under 800 bp
• Fine analysis of PCR? products
• AMPFLP, STR and tri- and tetranucleotide repeat analysis

Precautions
Always wear eye protection when dissolving agarose and guard yourself
and others against scalding solutions.
Microwave Instructions for
Agarose Preparation
1. Choose a beaker that is 2-4 times the volume of the solution.
2. Add chilled 1X or 0.5X electrophoresis buffer and
a stir bar to the beaker.
3. Slowly sprinkle in the agarose powder while the solution is rapidly
stirred.
4. Remove the stir bar if not Teflon® coated.
5. Soak the agarose in the buffer for 15 minutes before heating. This
reduces the
tendency of the agarose solution to foam during heating.
6. Weigh the beaker and solution before heating.
7. Cover the beaker with plastic wrap.
8. Pierce a small hole in the plastic wrap for ventilation.
For agarose concentrations
> 4%, the following additional steps will further help prevent the
agarose solution from foaming during melting/dissolution:
a. Heat the beaker in the microwave oven on Medium power
for 1 minute.
b. Remove the solution from the microwave.
c. Allow the solution to sit on the bench for 15 minutes.
9. Heat the beaker in the microwave oven on Medium power
for 2 minutes.
10. Remove the beaker from the microwave oven. Caution:
Any microwaved
solution may become superheated and foam over when agitated.
11. GENTLY swirl the beaker to resuspend any settled
powder and gel pieces.
12. Reheat the beaker on HIGH power until the solution
comes to a boil.
13. Hold at boiling point for 1 minute or until all of the particles are
dissolved.
14. Remove the beaker from the microwave oven.
15. GENTLY swirl the beaker to thoroughly mix the agarose
solution.
16. After dissolution, add sufficient hot distilled water to obtain the
initial weight.
17. Mix thoroughly.
18. Cool the solution to 50-60°C prior to casting. Once the gel is
cast, allow the
molten agarose to cool and gel at room temperature. The gel must
then be placed at 4° C for 20 minutes to obtain optimal resolution
and gel handling characteristics.
Hot Plate Instructions for Agarose Preparation
1 . Choose a beaker that is 2-4 times the volume of the solution.
2. Add chilled electrophoresis buffer and a stir bar
to the beaker.
3. Slowly sprinkle the agarose powder while the solution is rapidly stirred.
4. Weigh the beaker and solution before heating.
5. Cover the beaker with plastic wrap.
6. Pierce a small hole in the plastic wrap for ventilation.
7. Bring the solution to a boil while stirring.
8. Maintain gentle boiling until all the agarose is dissolved (approximately
1 0
minutes).
9. Add sufficient hot distilled water to obtain the initial weight.

11 . Cool the solution to 50-60°C prior to casting. Once the gel is
cast, allow the
molten agarose to cool and gel at room temperature. The gel must
then be
placed at 4° C for 20 minutes to obtain optimal resolution and gel
handling characteristics.
