The identification of protein modification sites and the identification of heterogeneity are the key links in the quality control of modified proteins, especially the analysis of PEGylation sites and identification of PEGylation heterogeneity are related to the pharmacokinetics, pharmacodynamic properties and stability of protein drugs. pegylation of proteins https://www.creative-proteomic....s.com/pronalyse/pegy

Circular dichroism (CD) spectroscopy is a fast, simple, and accurate method for studying protein structures in dilute solutions. The structural analysis was performed using the circular dichroism of proteins and the difference in absorption of left and right circularly polarized light by asymmetric molecules. circular-dichroism-near-uv https://www.creative-proteomic....s.com/pronalyse/circ

Bile acids formed by synthesis in the liver are termed primary bile acids. In the liver, synthesis of bile acids and bile salts is initiated with the conversion of cholesterol esters to cholesterol. The primary bile acids are conjugated with taurine or the amino acid glycine before secretion via bile into the intestine, where they function as detergents to solubilize dietary fats. Conjugation increases water solubility, preventing passive re-absorption once secreted into the small intestine. bile acids analysis feces https://metabolomics.creative-....proteomics.com/prima

Since its discovery in the 19th century, PC has been regarded primarily as a structural lipid. However, more recent evidence strongly suggests that PC has other roles. 1) PC can help boost cognitive function; 2) PC can aid in liver repair; 3) PC can help protect against medication side effects; 4) PC can help ease symptoms of ulcerative colitis; 5) PC can promote lipolysis; 6) PC can help dissolve gallstones. phosphatidylcholine assay method https://lipidomics.creative-pr....oteomics.com/phospha
