Provided herein are methods, systems, and compositions for detecting one or more HDL-associated proteins (e.g., ApoC3; ApoC3 and ApoA1; ApoC3 and SAA1/2; or proteins in Biomarker Panels 1-30) in a sample from a subject with, or suspected of having, cardiovascular disease (CVD) or other HDL related disease. In certain embodiments, such methods, systems, and compositions are used to determine the approximate risk of CVD (or other disease) for a subject, and/or the approximate cholesterol efflux capacity (CEC) of a sample.

HDL-associated protein biomarker panel detection

The present invention provides methods, kits, and compositions for purifying HDL molecules from a sample (e.g., blood sample) using HDL tagging molecules comprising an HDL lipophilic core binding peptide (e.g., portion of ApoA1) and an affinity tag. The present invention also provides methods, kits, and compositions for detecting non-fragmented ApoA1 with mass spectrometry. The present invention further provides methods, kits, and compositions for tagging HDL molecules in a sample with detectably labeled ApoA1 molecules such that the ratio of detectably labeled ApoA1 molecules to native ApoA1 proteins may be determined.

Compositions and methods for purification and detection of HDL and APOAI

Provided herein are compositions, systems, and methods for extracting and detecting at least one HDL-associated protein (e.g., ApoA1) from a sample (e.g., plasma or serum sample). In certain embodiments, a strong organic acid and hydrophilic organic solvent are mixed with the sample; after centrifugation, the supernatant is transferred to a second container where it is mixed with a non-polar organic solvent; after centrifugation, the lower aqueous layer is transferred to a third container; and then at least a portion of the transferred aqueous layer is subjected to a detection assay such that at least one HDL-associated protein is detected.
