Labeling Buffer is recommended for DNA labeling or mutagenesis. The PCR buffer system 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.
Labeling Buffer (green cap)
600 mM Tris-HCl (pH 8.8, 25 °C), 150 mM (NH4)2SO4, 20 mM MgCl2, 0.05 % Tween-20 and 0.05 % Nonidet P-40
Optimization of MgCl2 concentration:
A final Mg2+ concentration of 2.0 mM is recommended for most DNA labeling applications. However, if an individual Mg2+ 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|
|3 mM||0.8 μl||2.0 μl|
|4 mM||1.6 μl||4.0 μl|
|5 mM||2.4 μl||6.0 μl|
