Assessment of polymeric immunoglobulin A and M via detection of the joining chain

Nienke Oskam, Jim B. D. Keijser, Marij Streutker…·Theo Rispens

This paper develops sensitive ELISAs to quantify J-chain-containing IgA and IgM, revealing that 10% of circulating IgA is polymeric and enabling high-throughput analysis of polymeric IgA responses.
