Fig. 2From: Evaluation of two viral isolates as a potential biocontrol agent against the Egyptian cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae)a Agarose gel of 0.8% in TAE represents genomic DNA (137.9 kb) purified from occlusion bodies of nucleopolyhedrovirus isolates Spli-6 and Spli-7. b Partial amplification of polh gene by PCR using gene-specific primers. Spli-6 and Spli-7 isolated genomic DNA were used as a template for polh amplification for each PCR product separately. M1 represents 1-kb ladder. M2 represents 100-bp DNA ladderBack to article page
