CCMP908 was cryopreserved on Apr 6 1999 using 10% DMSO as a cryoprotectant.
The time required to regrow this culture, prior shipping, is approximately 24 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 strain starter cultures (2x15ml) and only starter cultures can be shipped within 24h of ordering (see aquaculture express ordering on the CCMP home page).

Q+A:
Q: I am interested in purchasing a start of Tetraselmis chuii. I have looked it up in your system and three strains listed as Tetraselmis sp. come up but none specifically identified as chuii. I am still on the search for a heterotrophically adaptable strain as it turns out that our current strain (maculata) does not seem to be readily adaptable. I suppose I have two questions; 1: Do you have a Tetraselmis chuii strain, 2: if so what kind of lead time would you need if I was to decide to order a start?
A: Any culture listed as sp. has yet to be identified down to the species. As a repository we depend on the depositor to provide all relevant information. That being said, we have a Tetraselmis that is regularly sold to aquaculture facilities, CCMP908. It does grow heterotrophically in our axenic testing under dark discipline.
