Title: An immunoenzymatic procedure for human apo B-containing particles quantification using monoclonal antibodies. Author: Bustos P, Calvo C, Ulloa N, Quiroga A, Sepulveda J. Journal: Hybridoma; 1998 Aug; 17(4):395-401. PubMed ID: 9790075. Abstract: The present report describes a new monoclonal antibody-based enzyme immunoassay (ELISA) for the quantification of apolipoprotein (apo) B-containing particles in plasma. Native low-density lipoprotein (LDL) and a reference serum were utilized to prepare the standard curve. Three different antibodies to apo B-100--4A6E3, 6A10B10, and 2D9--all produced in our laboratory, were examined. The apparent affinity constants of the monoclonal antibodies (MAbs) 4A6E3, 6A10B10, and 2D9 were 2.9 x 10(9), 1.74 x 10(9), and 0.63 x 10(8), respectively. The standard curve was generated for an apo B-LDL range of 0.1 to 4.0 microg/ml. Evaluating the concentration of apo B-containing particles in plasma may allow for a more accurate assessment of the risk of coronary artery disease.[Abstract] [Full Text] [Related] [New Search]
