Abstract
Development of vaccine strategies against human papillomavirus (HPV), which causes cervical cancer, is a priority. We investigated the use of virus-like particles (VLPs) of the most prevalent type, HPV-16, as carriers of foreign proteins. Green fluorescent protein (GFP) was fused to the N or C terminus of both L1 and L2, with L2 chimeras being co-expressed with native L1. Purified chimaeric VLPs were comparable in size (∼55 nm) to native HPV VLPs. Conformation-specific monoclonal antibodies (Mabs) bound to the VLPs, thereby indicating that they possibly retain their antigenicity. In addition, all of the VLPs encapsidated DNA in the range of 6–8 kb.

Supplementary Figure 1: CsCl banding patterns observed for the fusion constructs. Two bands observed for GFP-L1 and L1-GFP constructs with the lower band fluorescing under UV (GFP). Three bands were observed for L1:GFP-L1 and L1:L2-GFP. (DOC 834 kb)

Supplementary Figure 2: Agarose gel stained with ethidium bromide, showing the banding of 6-8-kb DNA incorporated into the GFP fusion VLPs. A greater amount of DNA with a broader size range (6-8kb) was observed for GFP-L1 and L1-GFP. DNA of smaller size was observed in the L1:GFP-L2 and L1:L2-GFP VLPs. The fluorescence in the wells represents the GFP fusion VLPs. (DOC 114 kb)
