Cathepsin B and L treatment of HPV16 increases binding. Reporter virus binding was compared in 293 cells incubated with 3H labeled HPV16 reporter-virions treated for various amounts of time with (A) 37 pM cathepsin B protease or (B) 37 pM cathepsin L protease. Amount of binding was quantified by scintillation counter for the presence of 3H. Statistics were analyzed by 1 tailed t-test and found to be significant at P < 0.05 for (A) and P < 0.10 for (B).
