The time required to regrow this culture, prior shipping, is approximately 55 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+A:
Q: We CCMP1102 growing in our lab and I noticed that the shape of the cells is more of a square than a cylinder. They are growing at 2C, in F/2 media. The square shape is consistent, regardless of the age or growth phase of the culture. I am wondering if this is the normal shape for this strain or if something weird is happening.
A: The square shape is normal for this strain. It may be due to being in culture since 1982. I was documented in house as mostly single square shape cells with a few chains in December of 2000.
