InvivoGen provides human IgA antibodies that have been generated by recombinant DNA technology. These IgA antibodies are chimeric monoclonal antibodies composed of the constant domains of the human IgA2 molecule and variable regions of different origins. They have been selected for their ability to efficiently neutralize the biological activity of selected cytokines. The neutralizing activity of these IgA antibodies was determined using InvivoGen’s HEK-Blue™ Cytokine cells. Some of these IgA antibodies can also be used for flow cytometry.
