The invention relates to a monoclonal antibody specifically recognizing lipocalin-type prostaglandin D synthase, a hybridoma producing the monoclonal antibody, methods for detection of L-PGDS or diseases by the monoclonal antibody, and a kit for detection of L-PGDS by the monoclonal antibody. The mandrel has a top surface and an outer surface comprising a plurality of ridges and contoured surfaces extending to the ridges. The support includes first and second regulators of the contact member in widthwise and thickness directions, respectively, with a gap therebetween. The adhesive is received in the bonding groove of the second connecting part, then the first connecting part is received in the bonding groove. The body portion being positioned between said leading portion and said trailing portion.
