Longterm persistence of proteolytic activities in frass of Blattella germanica increases its allergenic potential
{{output}}
Chromogenic microplate assays in 96 wells were used to determine the stability of enzyme activity in frass of Blattella germanica (Blattodea: Blattellidae). Frass samples were exposed to controlled conditions [temperature 15-35 °C and/or 53-100% relative humi... ...
