Abstract:
An apparatus for conducting a membrane flow-through assay, comprising:a plate for carrying a cartridge having a membrane with a binding member for binding an analyte of interest,a base being movably coupled to the plate for supporting the plate and for allowing the plate to move about at least one axis,an agitator coupled to the plate and being positioned within the base for moving the plate in a selected motion about the axis, anda vacuum pump capable of generating a negative pressure and being positioned within the base in fluid communication to the plate for allowing the negative pressure to be applied to a cartridge for drawing a fluid sample through a membrane of the cartridge,whereby action of the agitator and the vacuum pump can allow a fluid to diffuse through substantially the entire membrane.
