This direct PCR mix is easy and ready to use, can amplify blood DNA without any purification. Can amplify the High GC template DNA and oligos effectively.

Quality Control:

This product has passed the following quality control assays: functional absence of double- and single-stranded endonuclease activity; >90% homogeneous by SDS gel electrophoresis.

Application:

Blood direct PCR

Storage:

Store at -20°C

Reaction Mixture Set Up

Note: We recommend take ≤10% whole blood as the template DNA. Gently mix well all the component with the vortex mixer after adding blood.
Primer concentration 0.1-1.0 μM As a reference to the setting range. When low Amplification efficiency can increase Primer concentration, If there is non-specific amplification can reduce the primer concentration, thus optimizing the reaction system.

Recommended thermal cycling conditions

94°C 2 min
94°C 30 sec
55-60°C 30 sec, 35-40 cycles
72°C 30-60 sec
72°C 5min

Notes:

1) In general, the annealing temperature is 5°C lower than primer TM. If can not get the ideal amplification efficiency, can low down annealing temperature; If there is the non-specific amplification can increase annealing temperature
2) The extension time should be set according to the size of the amplified fragment. The amplification efficiency of the hot-start DNA Polymerase in the mix is 1-2 kb / min.
3) The number of cycles can be set according to the downstream application of the amplification product. If the number of cycles less, the amount of amplification is not sufficient; if the number of cycles is too large mismatch probability will increase, non-specific background is serious. Therefore, the premise of ensuring the yield of products should minimize the number of cycles.

no repeated freezing and thawing and split charging for good amplification.
