Popis: We have previously shown that Staphylococcus aureus contains molecules that bind CD14 and induce cellular responses. We have partially purified this activity and named the product active fraction (AF). Here, we further explore the chemical characteristics of AF. We show that 1) the activity is sensitive to base and hydrofluoric acid hydrolysis; 2) AF binds to Mono Q, indicating that it is negatively charged; 3) most activity in AF runs as a large species in aqueous buffer, but a small proportion runs with a size of
