Fig. 1From: Assessing the antigenicity of different VP3 regions of infectious bursal disease virus in chickens from South BrazilSchematic representation of VP3 fragments. Overlapping regions from the VP3 nucleotide sequence were PCR-amplified to generate three fragments of 390 bp (FA, FM and FP, 130 amino acids) and seven fragments of 150 bp (F1 to F7, 50 amino acids)Back to article page
