CCMP1051 was cryopreserved on Dec 28 2017 using 15% DMSO as a cryoprotectant.

The time required to regrow this culture, prior shipping, is approximately 14 days. If interested, please contact the CCMP for the cryopreservation methods (freezing and/or thawing protocols).

Note that aquaculture strains are always maintained as actively growing cultures, even if also cryogenically stored. Therefore, aquaculture strains (see aquaculture express ordering on the CCMP home page) can be shipped immediately upon request.

Q:       We are going to buy 1 liter from the strain:  CCMP1051 Thalassiosira weissflogii (Grun.) Fryxell et Hasle.  What are the conditions to maintain axenic the strain and what nutrients and concentration?

A:       CCMP 1051 is kept axenic by sterile technique under a Laminar Flow hood.  Click here for the L1 media recipe.

Q:       If I put 2 vials in the freezer, would that keep for 2 months without cell quality interruptions?

A:       Without following a cryopreservation protocol that includes a -80C freezer, liquid nitrogen vapor  and a cryoprotective agent I wouldn't recommend freezing cultures. Ice formation disrupts lipid bilayers and will destroy the viability of the culture.      

Q:       We were wondering if you may have nutritional profile?

A:       I am afraid that is not information that we have.
