Sex determination in neonate mice
Mouse (Mus musculus) tail tissue placed into equal volumes of Buffer A and Buffer B and incubated at 75°C for 5 minutes, followed by deactivation at 95°C for 10 minutes. Taq DNA Polymerase (MDX008) and X- and Y- chromosome-specific gene were added, amplified and the PCR products loaded onto an agarose gel. A single band is seen in five of the nine reactions (Lanes 1, 3, 5, 7 and 9) correspond to the XX (female chromosomes) and a doublet in the other four (Lanes 2, 4, 6, and 8) correspond to the XY (male chromosomes). The PCR product sizes were checked and corresponded exactly to a visual determination of the sex of the individual mice.
Tissue Extract-PCR Buffers, MDX004
Convenient, fast and efficient method for the extraction of DNA from a variety of mammalian tissues in a single tube, without the need for multiple washing steps for use directly in a PCR reaction.
Description
Tissue Extract-PCR Buffer offers a convenient, fast and efficient method for the extraction of DNA from a variety of mammalian tissues, particularly from rodent tail or ear samples. The DNA extractions are performed in a single tube, without the need for multiple washing steps, greatly reducing the risk of sample loss and contamination, and can be used directly in a PCR reaction.

FAQs: Tissue Extract-PCR Buffers
Yes, if it is not properly deactivated through the heat denaturation step, it could quickly degrade the polymerase during the PCR step.
Yes, the lysate can be used directly in a qPCR reaction, we recommend using the inhibitor-tolerant or Specimen-specific™ mixes.
Yes, the tissue extract can be stored at -20°C in the short term but for long term storage, we recommend purifying the DNA and re-suspending it in a standard buffer.
The Tissue Extract-PCR Buffers has been tested with cell cultures, tissues (tail, ear, kidney, liver, blood and FFPE), buccal swabs, stool samples, gram positive bacteria and hair follicles.
Depending on the sample type, it is possible to omit the centrifugation step after the extraction reaction, however pelleting the debris will result in a more reliable PCR.
