The present invention provides a kind of safe and reliable and economic methods to prepare improved dialysis liquid formulation to extracorporeal treatment, pass through blood filtration process, the method of the object of the relevant pathological states of Beta-Amyloid, it include KLVFF peptides or its variant including preparation, because of capture and adhesive, with a kind of carrier, the composition and dialysate constituents are mixed thus. The process using compact, cheap, easy standard dialysis machines that remove in vitro Beta-Amyloids without allow be discharged Beta-Amyloids return to patients body when, without the performance and characteristic intricately assessed, dialysis membrane, the health status risk without making object.
