name
descriptionImmunoglobulins are made up of two identical heavy chains which define the immunoglobulin class (A, G, or M) and two identical light chains, kappa or lambda (κ or λ). Each light chain is bound to a heavy chain. This assay quantitates the absolute value of the IgMκ, IgMλ , IgGκ, IgGλ, IgAκ and IgAλ separately, along with their ratios (IgMκ/IgMλ, IgGκ/IgGλ, and IgAκ/IgAλ ).
