Taq Core Kit Apta+ contains all reagents required for PCR (except template and primer) in one box combining simple handling with high flexibility. Taq Polymerase is recommended for routine PCR applications (up to 4 kb fragment length), high throughput PCR or genotyping. The buffer system guarantees robust and reliable amplification results in almost all PCR applications. The buffer contains a well-balanced ratio of potassium-, ammonium- and magnesium-ions to ensure high specificity and minimal by-product formation without the need of additional optimization steps.
Ruby Buffer contains gel loading buffer and an inherent red dye allowing the direct loading of the PCR product into the gel. The red dye allows an easy visual control during PCR set-up and in combination with the density reagent the direct loading of the reaction product into the gel.
The enzyme replicates DNA at 72 °C. It catalyzes the polymerization of nucleotides into duplex DNA in 5'→3' direction in the presence of magnesium. It also possesses a 5'→3' polymerization-dependent exonuclease replacement activity but lacks a 3'→5' exonuclease (proof-reading) activity.

Activation step
Hot Start Polymerase Apta+ requires no prolonged heating or denaturing step. The polymerase inhibiting aptamer is quickly released at the increased temperature of thermal cycling.

Assay Set-Up:
Before starting, vortex all components thoroughly to ensure homogeneity.
Prepare a premix for the number of assays you need according to the following protocol:

comp. stock conc. final conc. 1 assay @20 μl 1 assay @ 50 μl
PCR-grade Water     fill up to 10 μl fill up to 30 μl
Ruby Buffer or Crystal Buffer 10x 1x 2 μl 5 μl
dNTP Mix / 10 mM 10 mM 200 μM 0.4 μl 1 μl
Hot Start Polymerase Apta+ 5 units/μl 0.025 units/μl 0.1 μl 0.25 μl
primer mix or each primer 10 μM each primer 200 - 400 nM each primer 0.4-0.8 μl 1 - 2 μl
/sample DNA
    10 μl < 10 ng DNA 20 μl < 20 ng DNA

Select PCR tubes, stipes or plates as recommended for your cycler model.
Aliquot premix into each well and add template DNA (or PCR-grade Water for negative controls).


Cycling Conditions:
Spin down the tubes/plate briefly to remove bubbles and place them into the cycler.

1)The annealing temperature depends on the melting temperature of the primers used.
2)The elongation time depends on the length of the fragments to be amplified. A time of 1 min/kb is recommended.


Gel Loading and Down-Stream Applications:
Ruby Buffer (#PCR-272) includes a density reagent + tracking dye and allows the direct loading of the PCR products into a electrophoresis gel. For DNA detection / fluorescent DNA staining we recommend to use new generations dyes (i.g. SYBR DNA Stain, #PCR-273) instead of the classical but highly mutagenic ethidium bromide.
Crystal Buffer(#PCR-271) is recommended for down-stream applications such as DNA sequencing, ligation, restriction digestion or where an analysis of the PCR product by absorbance or fluorescence excitation is required. For gel electrophoresis add gel loading buffer and fluorescent DNA stain (i.g. Gel Loading Buffer with DNA Stain, #PCR-274 - #PCR-276) before loading the PCR into the gel. Using pre-stained gels or post-run staining protocols is also possible.

Additional Buffer Systems:
Labeling Buffer (#PCR-263) is recommended for DNA labeling or mutagenesis applications. The buffer is specially optimized for incorporation of labeled or modified nucleotides into DNA. It gives superior results in a broad range of reaction conditions with most primer-template pairs but amplification may also tend to an increased unspecifity.
KCl Buffer (#PCR-262) is recommended for use in routine PCR reactions. The buffer is optimized for highest specificity but may require additional fine-tuning of assay parameters like MgCl2 concentration and annealing temperature.

Optimization of MgCl2 concentration:
A final MgCl2 concentration of 2.0 mM is recommended in combination with Labeling Buffer. However, if an individualMgCl2 optimization is essential add 25 mM MgCl2 stock solution (#PCR-266) as shown in the table below.

final MgCl2 conc. 20 μl final assay volume 50 μl final assay volume
2 mM - -
3 mM 0.8 μl 2.0 μl
4 mM 1.6 μl 4.0 μl
5 mM 2.4 μl 6.0 μl
