采用金葡菌固相抗体技术特异地吸附水样中的ｆ２噬菌体获得较好的效果。先用滤料物理吸附ｆ２噬菌体，然后用３Ｘ肉汤洗脱，再用金葡菌固相抗体特异地吸附洗脱液中的ｆ２噬菌体。结果，当金葡菌固相抗体与洗脱液的体积比＝１：１０，样品中ｆ２噬菌体的浓度为１０４～１００时，吸附率可达８０％～１００％，并使ｆ２噬菌体浓缩近５０倍，为进一步ＰＣＲ检验提供了条件。本法操作简便、灵敏度高、特异性强、金葡菌固相抗体可冷冻干燥，便于长期保存。
The use of Staphylococcus aureus solid-phase antibody technology specifically adsorbed f2 phage in water samples to obtain better results. The f2 phage was physically adsorbed with the filter material and then eluted with 3X broth. The staphylococcus aureus solid phase antibody was used to specifically adsorb f2 phage in the eluate. As a result, when the volume ratio of Staphylococcus aureus solid-phase antibody and eluate was 1:10 and the concentration of f2 phage in the sample was 104-100, the adsorption rate could reach 80% -100%, and the concentration of f2 phage was nearly 50 Times, provided the conditions for further PCR test. This method is simple, high sensitivity and specificity, Staphylococcus aureus solid-phase antibody can be freeze-dried, easy to long-term preservation.
