SPLIT RNA Extraction Kit
The SPLIT RNA Extraction Kit enables a fast and highly efficient extraction of RNA that is free of genomic DNA contamination. The RNA can be recovered as total RNA or split into two fractions, large RNA and small RNA, facilitating the analysis of e.g., mRNA and miRNA from the same sample. Thus the RNA obtained is ideal for seamlessly preparing libraries for Next Generation Sequencing of total RNA or its large and small fractions or any other demanding downstream application. The SPLIT RNA Extraction Kit for Blood enables concomitant depletion of globin mRNAs from human blood samples in low volumes (50 – 250 µl).
SPLIT Rapid Viral RNA/DNA Extraction Kit is available for fast and easy extraction of viral RNA from fluid samples (e.g. for SARS-CoV-2 analysis).
The SPLIT RNA Extraction Kit contains reagents for the isolation of total RNA or the large RNA fraction from 48 samples, or small and large RNA fractions from 24 samples.
