MagMAX™ DNA 多样品 Ultra 试剂盒的 DNA 结合珠

We have optimized protocols for extracting DNA from buccal swabs, whole blood, blood cards (Whatman FTA), oral rinse, saliva, and urine samples. In addition, the kit can be used to process vaginal microbiota samples (e.g., ThinPrep, Surepath) for gDNA extraction from yeast, bacteria (Gram positive/negative), viruses, and protozoa with the addition of additional enzymatic steps.

On rare occasions, the sample may turn cloudy after adding the Multi-Sample DNA Lysis Buffer. The sample will clear up when isopropanol is added. This will not have any impact on the yield or quality of the DNA.

Heparin is not recommended as an anti-coagulant since it can cause inhibition of PCR reactions. Instead, we strongly recommend collecting blood samples in EDTA or sodium citrate.

We recommend transferring the lysate to a new MagMAX Express-96 Deep Well Plate (Cat. No. 4388476). This option eliminates contamination risks and saves time. To transfer lysates, set a multi-channel micropipetor to ˜300 µL and transfer one row at a time. Each well should contain 200-250 µL after transfer.

Buccal swabs can be shipped at 25 degrees C or below. Exposure of the swabs to high temperatures (over 30 degrees C) during shipment has been associated with poor performance in the workflow. To prevent degradation, ensure that buccal swabs are completely dry before shipment. Place the swabs in a paper envelope for storage after collection - paper envelopes are permeable and allow the swabs to dry effectively.
