The total protein concentration was determined by the Bradford method (Coomassie Plus Protein Assay Kit, Thermo, Waltham, MA, USA), and IgG, IgA, and IgM concentrations by sandwich enzyme-linked immunosorbent assay (ELISA) kits (Human IgG, IgA, and IgM ELISA Quantitation Set, Bethyl Laboratories, Montgomery, TX, USA) [20 (link)]. Complements C3 and C4 were measured with a polyethylene glycol (PEG)-enhanced immunoturbidimetric method using an ADVIA 2400 Chemistry System analyzer (Siemens Healthcare Diagnostics, city?, NY, USA). Albumin determination used a bromocresol green solution (BCG) as a binding dye, and the albumin-BCG complex was measured as an endpoint reaction at 596/694 nm. The purity of the gamma protein was assessed by zone electrophoresis using a Hydragel 7 protein kit (Sebia, Evry, France) [22 (link)]. Sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE) under non-reducing or reducing conditions was run using a NuPAGE 4%~12% Bis-Tris Gel (Invitrogen, Carlsbad, CA, USA) and a PageRuler prestained protein ladder (Thermo). Separated proteins were stained with Protein Gel Fast Stain (Strong Biotech, Taipei, Taiwan) [22 (link)].

Metabolic Characterization of Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
The weight and blood glucose levels of the mice were measured after fasting for 6 h every 4 weeks. Blood insulin levels were estimated using an enzyme-linked immunosorbent assay kit (Cloud-Corp, Wuhan, China). Homeostatic model assessment of insulin resistance was evaluated using the following formula: (fasting blood glucose [mmol/l] × fasting serum insulin [mIU/l])/22.5. Glucose tolerance test assays were performed at the 23rd week as described previously: animals were injected (ip) at a dose of 1 g/kg after 6 h of fasting. Blood glucose levels were measured at baseline and at 15, 30, 60, and 120 min after glucose injection, and the area under the curve was calculated using the conventional trapezoid rule.
Levels of serum lipid triglyceride, total cholesterol, alanine aminotransferase, and aspartate aminotransferase were measured using an ADVIA 2400 Chemistry System Analyzer (Siemens, Tarrytown, NY).

The hepatic lipid triglyceride (TG) contents were quantified by using commercial TG kits (A110-1-1, Nanjing Jiancheng Bioengineering Institute) according to the manufacturer’s directions. To assess the lipid content in the plasma and evaluate liver function, the serum levels of TGs, total cholesterol (TC), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were evaluated in the animals. For the analysis, an ADVIA 2400 Chemistry System analyzer (Siemens, Tarrytown, NY) was employed, following the guidelines provided by the manufacturer.

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.
