• Absolute Quantification of the Proteome
Proteomic quantitative methods include relative quantification and absolute quantification. Relative quantification, also known as comparative proteomics, refers to comparing and analyzing the relative changes in protein expression levels in different physiological and pathological states of cells, tissues, or body fluids. Absolute quantification of proteomics measures the absolute amount or concentration of each protein in the cell, tissue, or body fluid proteome.

• Isoelectric Focusing Electrophoresis to Determine Protein pI
Proteins are ampholytes and their charges come from the ionized groups on the side chains of amino acids. These groups can dissociate in solutions at certain pH values, resulting in a net charge on the protein. When a protein solution is at a certain pH, the tendency for the protein to dissociate into positive and negative ions is equal, making it a zwitterion with a net charge of zero. This pH is known as the protein's isoelectric point (pI).

• ATR FT-IR Method for Analysis of Monosaccharide Composition
ATR FT-IR method (Attenuated Total Reflection Fourier Transform Infrared Spectroscopy) is an effective technique for analyzing monosaccharide composition. This technique utilizes the infrared absorption characteristics of specific functional groups in monosaccharide molecules to identify and quantify monosaccharides.

• Arginine Modification Proteomics
Proteomic studies of arginylation focus on investigating a specific post-translational modification, arginylation, on proteins. Arginine, also known as guanidinoarginine, is a semi-essential amino acid that can be obtained through diet and endogenous synthesis in adults, but may need to be directly consumed from food or supplements in infants and certain health conditions. Arginylation refers to the covalent attachment of an arginine residue to another amino acid residue on a protein.

• Methylation Protein Detection
Methylation of proteins refers to the protein modifications that have undergone methylation. Methylation modification is crucial for cellular functions and signal transduction, involving the addition of methyl groups (CH₃) to specific amino acid residues of proteins. This modification can alter the function, location, stability, or interaction with other molecules of the protein. Methylation can affect the stability, activity, and interaction with other molecules of the protein.
