Fig 1. Enveloped virus infectivity recovery after lyophilization.

Fig 1

Chikungunya virus and Herpesvirus type 1 were freeze dried with/without different stabilizers using two different protocols (LP1 and LP2). After seven days at different temperature storage (-20°C, +4°C, +20°C), infectivity of each virus formulation were determinate by TCID50 assays. Chikungunya virus infectivity after storage at -20°C, +4°C, +20°C. Herpesvirus type 1 infectivity after storage at -20°C, +4°C, +20°C.* TCID50/ml >108.
