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.

For other uses, see Precursor (disambiguation) . A protein precursor, also called a pro-protein or pro-peptide, is an inactive protein (or peptide) that can be turned into an active form by posttranslational modification. The name of the precursor for a protein is often prefixed by pro.Examples include proinsulin and proopiomelanocortin.ike other proteins that contain a signal peptide, their name is prefixed by pre. They are thus called pre-pro-proteins or pre-pro-peptides. The signal peptide is cleaved off in the endoplasmic reticulum. An example is preproinsulin.
