Application

10X PCR Buffer without MgCl₂ has been used as a component of polymerase chain reaction (PCR) amplification mixture for the mycotoxigenic mould DNA, parasite DNA and Fusarium oxysporum DNA amplification.It has also been used as a component of the PCR mix for the amplification of nuclear ribosomal internal transcribed spacer (ITS2) and the partial ribulose-1,5 bisphosphate carboxylase/oxygenase large subunit rbcl gene for molecular and morphological characterization of Ulva sp from the Persian Gulf.

10× PCR Buffer without MgCl₂ has been used with Sigma′s PCR enzymes.

General description

10X PCR Buffer II was tested at a final concentration of 1X (10mM Tris-HCl, pH 8.3 at 25 °C, 50mM KCl), in reactions containing 1-4mM MgCl₂, each dNTP at 200 µM, primers defining an approximately 500 base pair region of λ DNA at 1.0µM each, λ DNA template at 1ng/100µL, and Taq DNA polymerase at 2.5 units/100µL. The reaction underwent 25 cycles of 94 °C to denature the double stranded DNA, 55 °C to anneal the DNA segments and 72 °C to extend the DNA segments. Following electrophoresis of the reaction products in 1.5% agarose gel, a single band of approximately 500 base pairs was visualized for PCRs containing 1-1.5mM MgCl₂.
