Abstract:
1. An affinity-chromatography strip having a planar surface and a longitudinal axis, said strip comprising: (a) a first location having a first movably immobilized flowable component comprising a first bio-reagent and a biopolymer; (b) a second location having a second immobilized component comprising a second bio-reagent; and (c) optionally a third location having a third immobilized component comprising a third bio-reagent; wherein said first and second locations are spaced at a first distance along the longitudinal axis and said third location, when present, is spaced at a second distance along said longitudinal axis from said second location; and wherein the flowable component, when entirely immersed in a buffer solution optionally comprising a fourth bio-reagent, forms a discrete volume at the first location that:
