Abstract
This unit describes an ELISA for the quantitative measurement of IgD levels in human serum. The ELISA is highly specific and sensitive, with a minimum detectable concentration of 30 pg/ml and more than 10,000-fold specificity for IgD over all other human immunoglobulins. Linear dilution characteristics enable measurement of IgD concentrations ranging over 5 orders of magnitude. These factors are vital for the IgD assay, since IgD makes up only a small proportion of the total immunoglobulins present in normal sera, and IgD serum concentrations are known to vary widely between individuals.
