Patent ID: 7060452

Claim:
A method for determining the effect of a therapeutic agent on altering net cholesterol mass flux comprising the steps of: a) obtaining a first serum sample from a subject; b) determining the net cholesterol mass flux mediated by a first serum sample by a′) providing cholesterol containing cells; b′) quantifying a first cellular cholesterol mass for said cholesterol containing cells; c′) exposing said cholesterol containing cells to a serum sample for a period of time sufficient enough to allow cholesterol flux to occur; d′) quantifying a second cellular cholesterol mass for said cholesterol containing cells after the exposure to said serum sample; and e′) comparing said first and second cellular cholesterol mass, wherein an alteration of said second cellular cholesterol mass compared to said first cellular cholesterol mass indicates the capacity of the said serum sample to cause net cholesterol mass flux; c) administering an effective amount of said therapeutic agent to said subject; d) obtaining a second serum sample from said subject after the administration of said therapeutic agent; e) determining the net cholesterol mass flux mediated by the second serum sample by the assay according to steps a′) through e′); and f) comparing said first and second net cholesterol mass flux, wherein an alteration of said second net cholesterol mass flux compared to the first net cholesterol mass flux indicates the capacity of said therapeutic agent to influence net cholesterol mass flux.
