Ancillary Reagent Kit Available  

DY008, DuoSet ELISA Ancillary Reagent Kit 2 -

This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and recombinant human Regenerating islet-derived protein 3 alpha (Reg3A). The suggested diluent is suitable for the analysis of most cell culture supernate, serum, and plasma samples. Diluents for complex matrices, such as serum and plasma, should be evaluated prior to use in this DuoSet.

Background: Reg3A

The Reg family constitutes a subset of the calcium-dependent C-type lectin superfamily. These small, secreted proteins have been implicated in a range of physiological processes including acting as acute phase reactants, lectins, survival/growth factors for insulin-producing pancreatic beta-cells, neural cells, and epithelial cells of the digestive system. Studies also indicate a role for Reg family members in tumor formation and indicate their potential for use as biomarkers of carcinogenesis.

Reg3A also named lithostathine 3 and pancreatitis-associated protein 2, belongs to the Regenerating gene family of C-type lectins. Reg3 is overexpressed during the acute phase of pancreatitis.
