Microarray RNA amplification & Labeling - Rhesus monkey brain tissue Biotin

Microarrays enable researchers to monitor the expression of thousands of genes simultaneously. However, the sensitivity, accuracy, specificity, and reproducibility are major challenges for this technology. Cross-hybridization, combination with splice variants, is a prime source for the discrepancies in differential gene expression calls among various microarray platforms. Removing (either from production or downstream bioinformatic analysis) and/or redesigning the microarray probes prone to cross-hybridization is a reasonable strategy to increase the hybridization specificity and hence, the accuracy of the microarray measurements.

Protocol tips
Check the cDNA Binding Buffer for precipitation before using it. If a precipitate is visible, redissolve it by warming the solution to 37°C for up to 10 min and vortexing vigorously. Cool to room temperature before use
Upstream tips
cDNA templates should be cleaned up
using phenol:chloroform followed by
ethanol precipitation. For ethanol
precipitation, add ammonium acetate to 2.5M, then add 2.5 volumes of absolute ethanol (-20°C).
