Objective Phageparticle antigens were used as a model antigen to investigate the potential mechanism of cross presentation.
目的以噬菌体颗粒抗原为模式抗原，研究其交叉呈递的可能机制。

Both these are virulent phages, meaning that whenever a phageparticle attacks a bacterial cell that cell is inevitably killed.
它们都是烈性噬菌体，也就是说这种病毒颗粒一旦侵袭细胞，细胞就必然死亡。

In addition to at least one normal phage or virus component the particles comprise at least one additional factor that is not encoded by the genetic material of the chimeric particle.
