Dear Sir/Madam, With reference to Catalogue number # E1186h.We at Quorum Innovations, Sarasota, FL purchased Human Filaggrin ELISA Kit. Half of kit was saved for repeated use.The problem is that small eppendorf tubes for detection reagent A,and detection reagent B are similar.They got mixed up after first use.Is there a diagnostic test based on colour reaction to identify which eppendorf is detection reagent A,and other as detection reagent B.

Hi, How many days it will take if I order E1186h (Filaggrin ELISA kit) from US using express shipping service, Thanks
