Distearoyl phosphatidylcholine (DSPC), distearoyl phosphatidylethanolamine methoxy(polyethylene glycol) conjugate (DSPE-PEG2000), cholesterol, and indocyanine green dye (ICG) were purchased from Sigma-Aldrich Co. (St. Louis, MO). scVEGF-PEG3400-DSPE conjugate was prepared by site-specific conjugation of DSPE-PEG3400-maleimide (Nektar Therapeutics) to [C4]-monothiol-scVEGF (SibTech, Inc. Brookfield, CT), using a four-fold molar excess of DSPE-PEG3400-maleimide and 10 min incubation at room temperature. Phospholipids C was purchased from Wako Diagnostics (Richmond, VA). Omniscan (GE Healthcare, gadodiamide injection) was used as a T1 contrast agent, and Feridex I.V.® (Bayer HealthCare Pharmaceuticals Inc., ferumoxides injectable solution) and nanomag®-D-spio (micromod Partikeltechnologie GmbH, Rostock, Germany) were used as T2 contrast agents. All other solvents or chemicals were of reagent grade.

Lipid Extraction and Quantification

Lipids were extracted from a section of liver at 4 °C overnight in 20 × 2:1 chloroform:methanol solution. An equal volume of phosphate-buffered saline (PBS) was added to the chloroform:methanol and mixed vigorously for 2 min and then spun for 15 min at 4 °C at 3000 rpm in a Sorvall™ Legend™ XTR Centrifuge TX-1000 (Thermo Scientific). The bottom layer containing the lipids in chloroform was extracted, and the chloroform was left to evaporate in the fume hood. The lipids were re-suspended in 1 mL of Isopropanol 10% Triton X-100. Cholesterol and triglyceride assays were performed as just described. Phospholipids were measured using a phospholipid-specific enzymatic assay from Wako (Phospholipids C).

Lipoprotein Separation and Analysis

We sterile-filtered the samples after incubation and applied 350 μl to the FLP for fractionation. We achieved separation using high-resolution SEC that consisted of three Superdex 200 increase columns (Cytiva) in-tandem (2 (link)) operating at a flow rate of 0.3 ml/min in STB. We monitored the lipoprotein distribution in real time using a Dionex Ultimate 300 (Thermo Fisher Scientific) equipped with a flow cell integrated between the last Superdex columns and the fraction collector. The Dionex acquired signal by sampling at 2 Hz with an excitation wavelength of 560 nm and an emission wavelength of 583 nm. We obtained the plasma signal at a sensitivity setting of 1 and CSF signal at a sensitivity setting of 8. We eluted samples with five single column volumes of buffer (~120 ml) and collected 1-ml fractions that we sealed and stored at 4°C until ready for analysis. For plasma, we determined phospholipid content enzymatically (Phospholipids C, Wako) on individual fractions as previously described (2 (link)).

Comprehensive HDL Composition Analysis

HDL chemical composition was measured using commercially available enzymatic kits, in the microplate reader Power Wave XS (BioTek®, Winooski, USA). Total proteins (Pierce™ BCA Protein Assay Kit, Thermo Scientific, Rockford, USA), TC (CHOD-PAP, total cholesterol, Roche Diagnostics® reagents, Mannheim, Germany), FC (Free Cholesterol E, Wako Chemicals, Richmond, USA), PL (Phospholipids C, Wako Chemicals, Richmond, USA), TG (TG, GPO-PAP, Roche Diagnostics® reagents, Mannheim, Germany) and ApoA-I (TINA QUANT APOA1 V2, Roche Diagnostics® reagents, Mannheim, Germany) were measured, while CE was calculated according to the following formula: (TC-FC) x 1.67 [12] . The relative content of ApoA-I (HDL-ApoA-I) or lipids in HDL was calculated based on their proportion to the total mass of HDL, calculated as the sum of FC, PL, TG, CE, and total proteins. HDL molar concentration was estimated based on particle total mass and molecular weight [12] .

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
