Assignment of Additional Anticapsular Antibody Concentrations to the Neisseria meningitidis Group A, C, Y, and W-135 Meningococcal Standard Reference Serum CDC1992

Abstract
We assigned additional enzyme-linked immunosorbent assay antibody concentrations (immunoglobulin G [IgG], IgM, and IgA, and total) to the Neisseria meningitidis standard reference serum CDC1992 for groups Y and W-135 to 12 Centers for Disease Control and Prevention quality control sera. These assignments will supplement previous assignments and will aid in the evaluation of present and developing vaccines.
