Sorry for an off-topic question. We began experiencing a sudden reduction in stability of baculovirus stock stored at 4C, like the titer drops more than 5 fold in 3-5 month. The only difference compared with previous preparations is a switch from Gibco SF900-II to a media from Lonza (Insect-XPRESS).
Could it be due to the media switch, or something else? What is the best way to store baculovirus? Thank you Alexander Aleshin Sanford-Burnham Medical Research Institute Infectious & Inflammatory Disease Center 10901 North Torrey Pines Road La Jolla, California 92037
