BIOARRAY™ Amplification & Labeling Systems

Optimized for routine GeneChip® analysis

Enzo’s BIOARRAY™ RNA Amplification & Labeling kits offer labeling solutions for biotin-based gene expression microarrays. Due to greater biotin incorporation and brighter signal, BIOARRAY™ RNA labeling is the best choice for routine GeneChip® analysis.


BIOARRAY™ Single-round RNA amplification and biotin labeling system

Improved data quality and array analysis through greater biotin incorporation:

Biotin-labeled antisense RNA (aRNA) is generated from total cellular RNA samples in less than 24 hours. Incorporation of two biotin nucleotides yields brighter signal, improving data from microarray experiments.

  • Convenient workflow with a flexible 4-16 hour transcription time and reagents supplied in a ready-to-use format.
  • Decrease experimental variation, and standardize data derived from microarrays.
  • Maintain the value of legacy data by the continued use of the gold standard for GeneChip® visualization.
  • Enables correlation of results from experiment-to-experiment, project-to-project and lab-to-lab.
  • Production of large amounts of biotin-labeled RNA targets by in vitro transcription from bacteriophage T7 RNA polymerase promoters is available separately with our BioArray HighYield® RNA Transcript Labeling Kits.

Analyze Limiting Quantities of Total RNA

Analyze limiting quantities of total RNA with the BIOARRAY™ Low Input RNA Amplification and Biotin Labeling System for transcript analysis

  • Generates sufficient aRNA for standard microarray analysis from as little as 20 ng of total input RNA.
  • Entire amplification reaction can be performed in a single tube.
  • Superior 3’/5’ transcript ratios demonstrating efficient in vitro transcription.
  • Biotin-labeled aRNA can be purified using either magnetic beads or purification columns and reagents

BIOARRAY™ 3´-OH Terminal Labeling is the recognized benchmark standard for biotin-labeling of DNA

The kit is considered the gold standard end-labeling system for use with Affymetrix® DNA SNP (single nucleotide polymorphism), resequencing and prokaryotic microarrays. This method uses Bio-ddUTP and terminal deoxynucleotide transferase to catalyze the addition of a single biotin-ddUMP (2’,3’-dideoxyuridine 5’-monophosphate) to the 3’-OH terminus of an amplified and fragmented target DNA molecule.

As little as 20 ng total RNA input produces sufficient amounts of aRNA for microarrays

Figure 1: Universal Human Reference RNA ranging from 20ng to 500ng was amplified in triplicate using BIOARRAY™ Low Input RNA Amplification and Biotin Labeling System. The lowest amount of input (20ng) generated enough labeled aRNA for microarray analysis.
