SEQguard™ Dino Preserve

Transport medium for purified RNA, enabling ambient temperature shipment to Plasmidsaurus for RNA-seq analysis.

SEQguard Dino Preserve is a transport medium optimized in partnership with Plasmidsaurus. It enables ambient temperature shipment of purified RNA samples for sequencing via the Plasmidsaurus pipeline.

SEQguard Dino Preserve is supplied as a solution in vials containing 150 μl liquid. Each 150 μl vial is sufficient to stabilize 24 purified RNA samples when used according to Plasmidsaurus’ usage guidelines.

FAQ and Support

At present, this guidance is based on Plasmidsaurus RNA-seq processing, as this is the context in which the product has been evaluated. If alternative downstream methods are used, performance should be validated independently.

RNA stability is also influenced by the quality of sample extraction and purification. High-quality RNA preparations (i.e., low RNase contamination and minimal metal ion presence) are associated with improved stability over time in SEQguard, whereas lower-quality preparations may result in faster degradation.

RNA should be eluted in a low-EDTA TE buffer (10 mM Tris, 0.1 mM EDTA), such as IDTE buffer (IDT, pH 7.5).

Samples can be submitted to Plasmidsaurus in either nuclease-free water supplemented with SEQguard Dino Preserve (mixed at the same ratio recommended for IDTE buffer: 24 μL RNA with 6 μL SEQguard Dino Preserve) or in IDTE buffer (10 mM Tris, 0.1 mM EDTA, pH 7.5).

Submission in IDTE buffer is recommended, as the addition of EDTA to a final concentration of up to 0.1 mM has been shown to improve RNA stability at elevated temperatures. Samples submitted in nuclease-free water will still be processed.

Ambient temperature: RNA in SEQguard has been shown to maintain high quality for Plasmidsaurus library preparation for 7 days, often longer. However, shipping times should still be minimized. Typical transit times are routinely acceptable without issue.
+4°C: Provides longer stability than ambient temperature.
−20°C: Suitable for storage over weeks to months.
−80°C: Suitable for long-term storage (effectively indefinite).
