Treatment of human sera with protein A reduced the amounts of immunoglobulin G (IgG), IgA, and IgM detected by radial immunodiffusion. This treatment also decreased the amount of herpes-specific IgG and IgM detected by radioimmunoassay, whereas it increased and even unmasked the amount of herpes-specific IgA detected. Comparison of protein A-treated sera with untreated sera indicated that herpes simplex virus type 1 IgG was responsible for more than 92 to 99% of the serum neutralizing activity.
用蛋白A处理人血清会减少通过放射免疫扩散法检测到的免疫球蛋白G(IgG)、IgA和IgM的量。这种处理还会降低通过放射免疫测定法检测到的疱疹特异性IgG和IgM的量,而它会增加甚至揭示出所检测到的疱疹特异性IgA的量。将用蛋白A处理的血清与未处理的血清进行比较表明,1型单纯疱疹病毒IgG占血清中和活性的92%至99%以上。
