• Principle of O-Glycan Modification and Site Identification
O-glycosylation is the process by which sugar chains are added to serine (Ser) or threonine (Thr) residues on proteins through glycosylation reactions. This modification significantly influences protein function, stability, and cellular signaling. Understanding the principles of O-glycosylation and methods for site identification is thus crucial for biological research and its applications.

• X-Ray Powder Diffraction Analysis of Peptide Drug
Peptide drugs are biologically active molecules composed of multiple amino acids linked by peptide bonds. Typically, they consist of 10 to 100 amino acids with a relative molecular weight below 10,000. Most peptide drugs originate from endogenous or natural peptides, thus they have little to no side effects on the human body. Compared to protein drugs, peptide drugs also offer advantages such as good stability, high purity, low production costs, and low immunogenicity.

• Inactivated Vaccine Viral Inactivant Residue Testing
Inactivated vaccines are vaccines that are made by culturing and then inactivating the pathogenic microorganisms. They are a common type of vaccine. By culturing and inactivating bacteria, viruses, or rickettsiae, the vaccines lose their pathogenicity to target organs while preserving the immunogenicity of the antigens. They can stimulate the immune system to produce an immune response, thereby achieving the purpose of disease prevention and treatment.
