Norgen’s EXTRAClean RNA Clean-Up and Concentration Micro-Elution Kit provides a rapid method for the purification, cleanup and concentration of up to 10 μg of RNA isolated using different methods including phenol/guanidine-based protocols, and from various upstream enzymatic reactions such as DNase treatment, labeling and in vitro transcription. The minimum recommended elution volume is 8 μL, which enables the concentration of small amounts of all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA). The RNA is preferentially purified from other reaction components such as proteins, RNases and nucleotides, without the use of phenol or chloroform. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including end-point or quantitative reverse transcription PCR, Northern blotting, RNase protection and primer extension, expression array assays and next generation sequencing.

This kit provides a rapid spin column method for the isolation and purification of genomic DNA from both Gram-negative and Gram-positive bacteria in milk samples. It can also be used to process challenging milk samples such as Mastitic milk for example. The kit is highly sensitive and can isolate DNA from a cell density of as little as 10 bacteria contained in 1 mL of milk. Genomic DNA is isolated in 45 minutes, free of inhibitors and ready for any number of downstream applications including PCR, qPCR and Southern Blot analysis, sequencing and more.
