title: Protein B: an important human IgA-binding reagent.
abstract: Protein B had a much higher affinity for human IgA than Jacalin, increasing the sensitivity and specificity of the measurement of total human IgA. Protein B, used as a capturing agent, greatly enhanced the measurement of antigen-specific IgA as compared to alpha chain-specific antibodies.
