Treatment of GLRaV-2 with glutaraldehyde: Preparations of purified GLRa V-2 were treated with 0,2% glutaraldehyde as described by Francki & Habili (1972), except that 0.1 M Tris-HCl buffer pH 7.6 with 0.01 M MgS04 was used.
Antisera production: Rabbits were immunised by four intramuscular injections, 2 weeks apart, with 0,5 mL preparations of purified GLRaV-2 mixed 1:1 with complete (first injection) and incomplete (all subsequent injections) Freund's adjuvant. Blood was collected 2 weeks after the last injection.
Mice (outbred, Swiss white) were immunised as described for rabbits. Preparations of 0,1 mL purified virus mixed with adjuvant were subcutaneously injected at three
week intervals. Blood was collected from the inferior vena cava (Campbell, 1984). Antisera was mixed with glycerol (1: 1) and stored at 4°C.
