A Step Towards Quantitative Lipoprotein Density Profi領(lǐng) Analysis: Applied Rayleigh Scattering Ultracentrifugation and imaging techniques of human blood serum are precise and information-rich methods for obtaining information about an individuals lipoprotein particle content. The information derived from lipoprotein separations via an ultracentrifuge plays a key role in the area of preventative medicine in regards to atherosclerosis. Two of the most critical lipoprotein characteristics, diameter and density, are well preserved with the proper isopycnic gradient. Currently, lipoprotein particles are stained, ultracentrifuged, and profiled through image analysis. This particular technique is helpful in determining particle density and can be correlated loosely with particle concentration. The need to completely quantify lipoprotein concentrations is imperative in assessing risk factors accurately. 麥奇克ZxinS3500系列激光粒度分析儀
