Product Information
Description: 3′-Sialyl-Lewis-a tetrasaccharide (Sialyl Lewis A; SLeA) is a carbohydrate-type antigen that can serve as a tumor marker. 3′-Sialyl-Lewis-a tetrasaccharide is involved in the migration and adhesion of tumor cells. 3′-Sialyl-Lewis-a tetrasaccharide has been used to inhibit the binding of 5B1 antibody to Sialyl-Lewisa -polyvalent biotinylated sLea-PAA.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
