TCS BIOSCIENCES LTD, CHANGE NOTICE: CCI 136

To: Customers purchasing Selectrol^®

It is our intention to change the source strain of the product listed below. The details of the change and the reason for it are given below..

If you have any difficulties or concerns accepting the change, please contact us immediately.

Product: Yersinia enterocolitica 1st generation derivative from NCTC^® 12982

Product code: MM80

Proposed Change Date: 01.12.2024

Change Details:

Storage conditions for this strain will be changed to -30°C to -15°C from -20°C to +8°C.

Reason for Change:

As part of our on-going shelf-life work we have recently completed a series of shelf life studies for MM80.

The results showed when stored at fridge temperatures (2-8°C) there are insufficient colony forming units to support the stated shelf life.

This strain will therefore be labelled for freezer storage (-30°C to -15°C) only.

Considerations:

All vials of MM80 despatched from 01 December will be labelled as described above.

We recommend that any existing stock of MM80 at customer facilities is transferred to freezer storage if it is currently refrigerated.
