Qiagen launches new genomic analysis kit

QIAGEN : 22 January, 2008  (New Product)
Qiagen has launched the REPLI-g FFPE Kit to support the genomic analysis of fixed tissue samples.
The new REPLI-g FFPE Kit, the latest development in Qiagen’s whole genome amplification portfolio, eliminates problems associated with DNA fragmentation and damage caused by formalin fixation. The kit uses a novel DNA processing reaction, allowing the advantages of multiple displacement amplification (MDA), a key technology in the amplification of genomic DNA, to be extended to highly degraded DNA samples derived from FFPE tissue.

Isolation of sufficient genomic DNA from formalin-fixed, paraffin-embedded (FFPE) tissue is often difficult due to the low amount of DNA available. The REPLI-g FFPE Kit allows amplification of precious sample material while maintaining locus representation, enabling unlimited downstream analyses to be performed. Highly uniform whole genome amplification directly from formalin-fixed, paraffin-embedded (FFPE) tissue can now be performed without the need for prior DNA isolation.

The REPLI-g FFPE Kit provides uniform amplification resulting in scalable and standardised DNA yields. Following lysis of the tissue section, the DNA is processed using novel buffers and enzymes that ligate fragmented DNA. The long DNA strands created by the ligation reaction are amplified using proven REPLI-g technology.

A two-hour amplification reaction typically yields 10g DNA, whereas 40g can be obtained after eight hours incubation. Once amplified, the DNA is suitable for immediate use in most downstream genotyping assays without further purification.
