Plasma biochemistry analyses of glucose (GLU), total cholesterol (TC), triglycerides (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), total protein (TP), blood urea nitrogen (BUN), and creatinine (CRE) were performed using an autoanalyzer (JCA-BM2250, JEOL Ltd., Tokyo, Japan) according to the manufacturer’s protocol. The plasma non-esterified fatty acid (NEFA) concentration was measured using a Wako NEFA-C test commercial kit (Wako Pure Chemical Industries, Inc., Tokyo, Japan). Commercial kits were used for measurement of plasma MDA concentration (NWK-MDA01), SOD activity (NWK-SOD01) and GPx activity (NWK-GPX01, Northwest Life Science Specialties, LLC, Vancouver, Canada). Plasma LDH isozyme pattern was confirmed by a QuickGel LD Isoenzyme kit (Helena Laboratories, Texas, USA) with an Edbank III analysis software (Helena Laboratories, Texas, USA).

Pre-prandial blood was collected from jugular vein into heparinized plastic tubes. These samples were immediately centrifuged at 1,700 × g for 10 min at 4°C to obtain plasma, and the samples were stored at −80°C until use. Plasma GLU, TG, total cholesterol (TC) concentrations and plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT) activities were measured using autoanalyzer (JCA-BM2250, JEOL Ltd., Tokyo, Japan) with the manufacturer’s reagents at Monolis Inc., Tokyo, Japan. Plasma non-esterified fatty acid (NEFA) concentrations were measured with a commercial kit (NEFA-C test, Wako Pure Chemical Industries, Ltd., Tokyo, Japan). Plasma INS and ADN concentrations were measured with a commercial kit (Cat Insulin ELISA kit, Shibatagi Co., Ltd., Gunma, Japan; Mouse/Rat Adiponectin ELISA kit, Otsuka Pharmaceutical Co., Ltd., Tokyo, Japan), respectively. Statistical analysis for plasma parameters was performed by Mann–Whitney U-test (p < 0.01).

Heparinized plasma was separated from the collected blood by centrifugation at 3000 ×g for 10 min. Plasma concentrations of alanine transaminase (ALT), aspartate aminotransferase (AST), total cholesterol (T-CHO), phospholipid (PL) and triglycerides (TG), and glucose in both the plasma and urine were measured using an automatic analyzer (JCA-BM 2250; JEOL Ltd., Tokyo, Japan). Plasma levels of insulin (Morinaga Institute of Biological Science Inc., Yokohama, Japan) and adiponectin (Otsuka Pharmaceutical Co. Ltd., Tokyo, Japan) were quantitated with ELISA kits.

We carried out a clinical-biochemical test using serum collected from ICR females at 13 weeks of age. The mice consumed experimental diets for 7 weeks. Blood collection, separation of serum, and analysis was performed as previously described [20 (link)]. In brief, we collected 200 μl of blood from the retro-orbital sinus using a Pasteur pipette (Thermo Fisher Scientific Inc., Waltham, MA). The collected blood was transferred to a microtube containing Coagulant Wako solution (Wako Pure Chemical Industries Co, Osaka, Japan) and serum was separated by centrifuging twice (600–2500×g for 5–15 min). We measured total protein (TP), urea nitrogen (UN), albumin (ALB), total cholesterol (T-CHO), HDL-cholesterol (HDL-C), triglyceride (TG), and LDL-cholesterol (LD-C) in the serum with an automatic clinical-biochemistry analyzer (JCA-BM2250, JEOL, Ltd., Tokyo, Japan). Number of subjects: CD, 7; PR, 7; FA, 6.

Heparinized plasma was separated from the collected blood by centrifugation at 3000×g for 10 minutes. Plasma levels of glucose, as well as electrolytes including sodium, potassium and chlorine in heparinized plasma, were measured using an automatic analyzer (JCA‐BM 2250; JEOL, Tokyo, Japan). Plasma insulin was measured using a rat insulin ELISA kit (Morinaga Institute of Biological Science, Yokohama, Japan). The plasma 8‐iso‐prostaglandin F concentration was determined by a Plasma 8‐iso‐prostaglandin F ELISA kit (Cayman Chemical, Ann Arbor, MI, USA).

Serum Lipid Metabolite Profiling

Check if the same lab product or an alternative is used in the 5 most similar protocols
Serum lipid metabolites and enzyme activities were measured. Glucose (GLU), TG, total cholesterol (T-Cho), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein, blood urea nitrogen (BUN), and creatinine (CRE) were determined using a biochemical auto analyzer (JCA-BM2250, JEOL Ltd., Tokyo, Japan) with the manufacturer’s reagents. Oxidized LDL was determined using a Dog Oxidized low-density lipoprotein ELISA (Kameyama Biomedical Company, WA, USA). This ELISA kit uses a mouse monoclonal antibody for all of malondialdehyde (MDA)-LDL, Nepsilon (carboxymethyl) lysine (CML)-LDL, and detects advanced glycosylation end product (AGE)-LDL; it cannot distinguish between them. We constructed a calibration curve by plotting the average optical density for each calibrator on the horizontal (X) axis against the concentration on the vertical (Y) axis, and drawing the best-fit curve to generate a four parameter logistic (4-PL) curve-fit.

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.
