| 摘要 |
The invention relates to a method and reagent for the specific determination of the LDL fraction in the presence of other serum lipoproteins by adding a water soluble polymeric LDL-aggregating agent and a zwitterionic and/or non-ionic detergent. The LDL aggregate is determined in a direct turbidimetric measurement. Preferred LDL-aggregating agents are polyanions having a branched structure with acid groups, particularly branched alkane sulfonic acid groups as side branches. Preferred detergents are those known as "Zwittergent". |
