Using analytical means to analyze products in all aspects from the perspective of physics and chemistry, whether it is to characterize reference products at different stages, evaluate different batches of products, or used for comparative research on biosimilar drugs or improved biological drugs, it will meet the requirements of scientific standards and international regulations.

What we can do:

Peptide level: amino acid sequence analysis, n/c-terminal sequence analysis, amino acid modification analysis, N-sugar site /o sugar site analysis, disulfide bond, peptide map / peptide spectrum

Protein level: complete molecular weight, desaccharide molecular weight

Subunit level: reducing molecular weight, desaccharide reducing molecular weight

Preparation level (advanced structure): UV spectrum, fluorescence spectrum, Raman spectrum, DSF, circular dichroism

Physical and chemical properties: protein content (extinction coefficient study), amino acid composition analysis, glycosylated protein, sialic acid content, sugar type (n glycoside /o glycoside), free sulfhydryl content, size heterogeneity, charge heterogeneity
