Hello,
I am looking to purify Coxsackievirus B3 (CVB3) and SARS-CoV 2 viruses by ultracentrifugation (Optima XPN from Beckman Coulter) and after several searches in the literature, I decided to use an iodixanol density gradient (OptiPrep). However, I find very different gradient protocols and ultracentrifugation settings and I am therefore lost. Could you tell me which gradient and ultracentrifugation settings would be the most adequate to purify CVB3 and SARS-CoV 2?
Thank you in advance for your answers.
