Methods The HPV16E7 gene was cut to three parts, amplified by PCR, and connected individually with BPVL1 on plasmid PUC. With PVL1393 as a transfect vector, the BPVL1/HPV16E7 recombinants were transfected to baculovirus which subsequently expressed the chimeric BPVL1/HPV16E7 protein in the SF－9 cells. The recombinant proteins were then purified by centrifuge, sonication, sucrose and CsCl ultracentrifuge, and were identified by SDS-PAGE, Western blot, ECL and TEM.

HPV16E7基因分3段经PCR扩增后分别克隆入连有BPVL1的质粒PUC形成BPVL1-HPV16E7；以质粒PVL1393为载体将BPVL1-HPV16E7基因转染杆状病毒并在昆虫细胞中进行表达；用超声粉碎和蔗糖超离、氯化铯梯度离心等方法纯化以及免疫印迹、ECL、透射电镜等方法鉴定表达产物。

Igniarius were carried out. It will be of scientific significance in researching and developing rare medicial fungi and be useful for searching new natural antitumor medicine.The crude polysaccharides of P. igniarius PIP30、PIP60、PIP80 and PIWE1-10、PIWE10-100、PIWE100 were obtained by ethanol precipitation and ultrafiltrate respectively after hot water extracting.
