The temperature for shipping is 4 degrees, and the storage buffer is Sf-900 II SFM and 2% FBS. For long term storage, the BV stock could be freezed in -80 degrees. However, if you store your viral stock at -80 degrees, the viral titers can decrease as much as 10% with each freeze/thaw cycle. For routine use, baculoviral stocks should be aliquotted and stored at 4 degrees and be protected from light. Baculovirus can be stored at 4 degrees for at most 6 months.
