Overview:

ApoB is a protein produced in the liver and intestine that provides structure to triglyceride (TG) carrying atherogenic lipoprotein particles. Each particle carries only one apoB protein. Thus, apoB is a direct measure of the number of atherogenic particles in the bloodstream. ApoB is also a surrogate marker for LDL particle concentration or LDL particle number since LDL comprises about 90% of the atherogenic lipoprotein particles.
