NOTE: 1  It is a good idea to label each equation. 2  This value of x can be substituted into equation [1] or [2], or into the expression for y: y = 2x â 1. 3  Choose the one that is easiest!  As a check, substitute the values back into each of the two starting equations.
Paraprotein. A paraprotein is an immunoglobulin or immunoglobulin light-chain that is produced in excess by the clonal proliferation of plasma cells. Detection of paraproteins in the urine or blood is most often associated with benign MGUS, where they remain silent, and multiple myeloma.araprotein.

Based on the type of the plasma cells, either whole immunoglobulins of IgG or IgM class are produced or just light or heavy chains are synthesised. The presence of paraproteins manifests itself in serum electrophoresis as a narrow and high peak in the band of Î³-globulins. If only light chains are synthesized, it is called Bence-Jones protein. Bence-Jones protein is filtered into urine, but the dipstick method for proteinuria is not sensitive to it.
