Description
The ExcelTaq™ 5X Blood Direct PCR Master Mix Kit is designed for amplifying targeted DNA directly from whole blood, eliminating the need for a lengthy DNA isolation process. ExcelTaq™ Blood Direct PCR Master Mix Kit is a unique blend of 5X concentrated mixture containing all the essential components of a PCR reaction. The ExcelTaq™ Blood Direct PCR Master Mix Kit also contains the PCR-friendly loading and tracking dye solution Orange G. The inclusion of Orange G tracking dye allows for a more convenient post-PCR gel electrophoresis analysis. ExcelTaq™ 5X Blood Direct PCR Master Mix Kit is capable of tolerating the presence of PCR interfering/ inhibiting substances in blood. The ExcelTaq™ 5X Blood Direct PCR Master Mix Kit is ideal for high-throughput screening of blood samples for high reproducibility. ExcelTaq™ 5X Blood Direct DNA PCR Master Mix Kit includes a pair of Positive Control Primers (CCR5) that are compatible with primate blood samples.
