High-quality mRNA is essential for gene expression studies, RNA sequencing, and RNA-based therapeutics. Oligo(dT)25 MagPoly beads provide a rapid and efficient method to isolate mRNA with high specificity from total RNA samples.
Oligo(dT)25 beads are magnetic polymer-coated beads functionalized with 25-base oligo(dT) sequences. These sequences selectively hybridize to the poly(A) tails of eukaryotic mRNA, enabling specific capture.
Workflow Overview:
Sample Preparation – Total RNA is prepared and free biotin or contaminants removed.
Binding – RNA is incubated with Oligo(dT)25 beads to hybridize mRNA to the oligo(dT) sequences.
Magnetic Separation – A magnet collects the bead-bound mRNA, separating it from unbound RNA.
Washing – Beads are washed to remove non-specific RNA.
Elution – High-purity mRNA is eluted for downstream applications or used directly on the beads.
High specificity – Selectively captures poly(A) mRNA, minimizing rRNA or tRNA contamination.
Rapid and easy – Magnetic separation streamlines the workflow.
Preserves RNA integrity – Gentle handling maintains mRNA quality.
Scalable and automation-friendly – Compatible with small-scale or high-throughput applications.
Gene expression studies (qPCR, RT-PCR, microarray)
RNA sequencing and transcriptomics
cDNA synthesis and molecular cloning
RNA therapeutics and vaccine development
Conclusion
Oligo(dT)25 MagPoly beads provide a fast, reliable, and high-specificity method for mRNA capture, making them ideal for research, diagnostics, and therapeutic applications where high-quality mRNA is required.
