Recombinant Protein & peptide Antigen Production Service

Antigen Production Service Introduction

Our antibody development services can accept antigens provided by our customers and can also help customers produce antigens. Obtaining high-quality antigens is the key factor to successfully develop antibodies. Sino Biological can provide peptide antigens and protein antigens. Protein antigens have integrit conformation. When the protein in sample is in its natural conformation, it is preferred to immunize with a protein antigen, such as the development of neutralizing antibodies.

If it is difficult to express the proteins or other specific detection requirements is needed, peptide antigens are economical and practical choices, such as the species-specific detection of the same protein. In addition, Sino Biological can also provide diversified immunization methods such as DNA, cells, and insect viruses to solve the protein expression problems and immunogens are closer to natural proteins.
