Preservation Plates Preservation Plates (Nucleic Acid / Blood) Another Option for Bioresource Storage Containers Watson’s Preservation Plate (PVP) has been developed in order to enable storage and transportation of such bioresources as nucleic acids (DNA / RNA / oligonucleotide) and blood under room temperature and pressure.Simply place such samples onto paper chips, then dry, the preservation is completed. Space Saving It is very compact and space saving in comparison with preserving in tubes samples of liquid condition. Marking space on the plate and compact body make sample storage management easier. Recover Samples Directly on PCR Plate Paper chips can be put directly into the solution to start PCR or in situ hybridization. Reduce Contamination Risk Compared to the traditional way of repeated samplings from the same tube, Preservation Plate (PVP) can reduce contamination risk by using different wells on the PVP and / or changing the PVP sheet itself dependent on the sample (Note: Only 96 well PVP can be cut easily with scissors). Prevent Sample Deterioration Sample deterioration is prevented as the PVP requires no repetition of freezing and melting. No Reagent or Salt Used Please find a suitable plate type for different bioresourses and sample volumes. Rich Selection Paper chips do not contain any reagents or salt so it does not choose type of eluent to be used when you recover samples. 【Sample Volume】 5 µL / sample ⇒ 96 Well 50 µL / sample ⇒ 3 Well 200 µL / sample ⇒ 1 Well 【Sample type】 Nucleic Acid(DNA, RNA, oligonucleotide, plasmid, RNA probe, genomic DNA etc.) ⇒ Nylon paper chip Blood, throat swab, feces etc.⇒ Cellulose paper chip Preservation Plate Lineup Dramatic savings per chip！ Made from Polypropylene: it is easy to cut！ Convenient well layout to match your 96 well plate！ Lower cost per well.

After 4 months of preservation under normal temperature. There is always a risk of contamination with RNase based on operator error which may influence the outcome of your experiment. Using PVP the samples remain in the same condition for every ISH providing you have preserved samples in a suitable amount for each experiment. The preservation period is more than 4 months under normal temperature. 2.DNA Preservation and Sequence Analysis Target DNA can be preserved and used for analysis in a later day. PVP with nylon paper chips is recommended for long chain samples like genomic DNA or high value samples. After sufficient drying, is possible to preserve samples for several months. (Preservation period may vary depending on the level of purification.) Preservation Plate has been developed from the study reslut of MEXT’s Intellectual Cluster Formation Project <Tokushima Region Noji group (The University of Tokushima)>.
