Sagarose^® low melting point agarose

Agarose with low melting point

1. Product description

Sagarose^® Low Melting Point Agarose is a modified agarose with special gel properties. Compared with conventional agarose, it has a lower melting temperature and gel temperature, and the gel can melt when the temperature reaches 65 °C, which is suitable for the recovery of DNA/RNA and enzymatic reactions in the gel after nucleic acid electrophoresis. After 45 min of sterilization at 121 °C, the gel strength of more than 100 g/^cm2 (1%) can be maintained, which is suitable for tissue culture cell cloning and viral vacancy experiments.

4. How to use

(1) Preparation concentration of agarose gel and optimal separation range of DNA

In the process of agarose gel electrophoresis, the appropriate agarose concentration and electrophoresis buffer should be selected according to the molecular weight of the nucleic acids to be separated by electrophoresis, so as to improve the resolution of nucleic acid molecules. Agarose gel concentration and linear DNA isolation range and electrophoresis solution are referred to the following table:

Procedure:

• Choose a beaker with a capacity of 2-4 times the volume of the solution and add pre-cooled 1× or 0.5 × of electrophoresis buffer and stirrer.

• Sprinkle in the agarose powder slowly while stirring quickly, and soak the agarose in the buffer for 15 minutes before heating to reduce foam formation when heating.

• Weigh the beaker and the total weight of the solution before heating, cover the beaker with plastic wrap, and make small holes in the plastic wrap for venting.

Note: If the agarose concentration >4%, the following steps should be performed to prevent foaming
A. Microwave over medium heat for 1 minute. B. Remove the solution and let stand for 5 minutes.

• Microwave over medium heat for 2 minutes and remove the beaker.

Note: Microwaved solutions may overheat and splash when shaken.

• Gently rotate the beaker to resuspend the settled powder or gel block.

• Heat over high heat until the solution boils, keeping boiling for 1 minute or until all particles are completely dissolved.

• Remove the beaker and gently rotate the beaker to mix the solution well.

• After dissolution, add an appropriate amount of hot water to the initial weight and mix well.

• After cooling to 50 °C-60 °C, the glue is filled to solidify at room temperature, and then placed in an electrophoresis tank for electrophoresis (recommended parameters: 1.0% AG0065LM, constant pressure 90 V, 50-70 min).

5. Precautions

1. This product is only for scientific research use and should not be used in clinical diagnosis and treatment.

When microwaving to dissolve, keep the heating time to a minimum, and always wear safety goggles to protect yourself and others from burns. The gel strength of this product is low, please place it on a hard plate and transfer.
