Abstract

A reagent assay having a tubular member having a cross-section. The assay further has a first porous alginate plug shaped having the cross-section within the tubular member and containing a first reagent and a second porous alginate plug shaped having the cross-section adjacent the first porous alginate plug within the tubular member and containing a second reagent.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A reagent assay, comprising:
 a tubular member having a cross-section;   a first porous alginate plug shaped having the cross-section within the tubular member and containing a first reagent; and   a second porous alginate plug shaped having the cross-section adjacent the first porous alginate plug within the tubular member and containing a second reagent.   
     
     
         2 . A method of modifying alginate, comprising:
 providing a sample of porous alginate; and   mixing in the alginate a reagent that is encapsulated by one or more pores in the alginate.
