Single tube reaction for amplification and labeling
Generates sufficient aRNA for standard microarray analysis from as little as 20 ng of total input RNA
Superior 3’/5’ transcript ratios demonstrating efficient in vitro transcription
3’/5’ ratios significantly better, as Enzo kit completes transcript through the 5’ end

The BIOARRAY™ Low Input RNA Amplification with Biotin Labeling System provides an optimized protocol and reagents for the production of biotin-labeled antisense RNA (aRNA) from total cellular RNA samples in less than 24 hours for array analysis. This kit has been improved to yield sufficient aRNA quantity for most microarray platforms (10 µg minimum) with total RNA input of as low as 20 ng and up to 500 ng. Entire amplification reaction can be performed in a single tube and the biotin-labeled aRNA can be purified using either magnetic beads or purification columns. The BIOARRAY™ Low Input aRNA Amplification and Biotin Labeling System has been optimized for superior performance with reduced variability and improved reproducibility and data quality. The complete system is composed of reagents for cDNA synthesis and in vitro transcript labeling.

Figure 1: Quality assessment of aRNA obtained using BIOARRAY™ Low Input RNA Amplification and Biotin Labeling System. The 3’/5’ ratios, on an Affymetrix U133a array, for housekeeping gene Actin obtained using Enzo kit are much lower than the ones from the competitor’s indicating higher quality of aRNA obtained using Enzo kit.
