Microbial Preservation Plates

Microbial strains such as E.coli and yeast can be dry-preserved on a paper chip coated with a preservation agent.
Samples can be sealed individually with an accessory protection seal to prevent contamination and inactivation.
This enables compact and efficient preservation at room temperature – it is no longer necessary to use deep freeze or dry ice for transportation.

How to Use

Preservation Method

1.Let the paper chip absorb a liquid sample.

A: For a liquid sample
B: For a sample from agar

2.Dry the sample.

*Reduced pressure drying is recommended.

Recommended dry time
[96 well] 60 minutes or more
[1/3 well] 90 minutes or more

3.Seal the plate with the protection seal and store it in room temperature.

Recovery Method

1.Peel off the protection seal and place the paper chip into a container.

Push the paper chips by tweezers etc.

Pick up the paper chip from tweezer hole.

Cut out the necessary size of paper chip.

2.Put the solution into the container and stir.
In the case of agar, rub the paper chip onto agar.

Preservation Plate has been developed from the study reslut of MEXT’s Intellectual Cluster Formation Project .
The verification experiments have been implemented under advice of Dr. A. Yokota and Dr. M. Kurahashi of Institute of Cellular and Molecular Biosciences, the university of Tokyo.
This project is supported by METI’s New Cooperation Measure Subsidy.
