Users only need to add templates and primers, and water if needed. Extra 25mM magnesium solution is also provided for additional fine adjustments. The Red Mixes contain a non-hazardous inert red dye. The purple mixes contain a non-hazardous inert purple dye. Completed PCR reactions utilizing the D124-R (red dye) or D124-P (purple dye) can be directly loaded into a well of agarose gel or other gels, for electrophoresis. No extra loading buffer is needed.
Storage: 4°C for up to one month, or -20°C for long term storage.
Magnesium Chloride: In general, 1.5mM MgCl2 is recommended; this may vary with different conditions and primer sets. Some primers/templates may require adjustments for MgCl2 concentration, which can be achieved as shown below:

Directions for use: For a 50µl reaction, use 25µl of the Taq Master Mix, add template, primers, and water to a final volume of 50µl. Cycling conditions vary for different templates and primers. To start with, try 30 cycles as follows: denature at 94°C for 30 seconds, anneal around 55°C for 30 seconds, and extend at 72°C for 1 minutes/kb. After the PCR cycles, extend at 72°C for another five minutes to complete the PCR. Then store the reaction at 4°C.
1x Composition: 10mM KCl, 20mM Tris HCl (pH9.0), 16mM (NH4)2SO4, 0.1% Triton X-100, 1.5mM MgCl2, 200mM dNTPs, 2.5units/25ul of Taq DNA polymerase, (optional: trace amount of red or purple dye) and enzyme stabilizers.
