Capture moieties are usually be applied by systems which get in touch with the membrane, or noncontact systems which use capture moieties as beads or streams of liquid; the capture moieties are usually be applied as a strip or line across the membrane. The terms upstream and also downstream are utilized in describing the side flow assay strips to refer to the loved one placements of areas on the strip. The sample and optional elution reagent are added at one end of the strip as well as circulation downstream to the other end of the strip. Elution Reagent or Elution Barrier Offers Neutralization In some elements of the innovation, the elution reagent or buffer can supply the neutralization of the decomplexation reagent that is needed for removal of the decomplexation reagent from the downstream portions of the strip. For instance, the elution barrier can have reagents that react with the decomplexation reagents for neutralization.
