Project Name	Content
Antibody Purification Services	We provide various antibody purification methods such as protein A/G affinity purification, antigen affinity purification, etc.
Antibody Pairing (Custom ELISA Assay Development)	Antibody pairing is critical for the development of ELISA kits. Our antibody staff have extensive experience developing clinical assays and can provide comprehensive enzyme-linked immunoassay kit development services, including detection sensitivity verification, linear range verification, repeatability verification, specificity verification, and thermal stability (37 °C or 25 °C thermal stability) verification. We have successfully developed a small molecule detection kit with a detection sensitivity of 0.1 ppb.
Antibody Sequencing Services	Gxene Biotech uses the most advanced Orbitrap Fusion Lumos mass spectrometer and powerful antibody sequencing data processing software, combined with gene sequencing and bioinformatics database, established a new generation of antibody sequencing platform to achieve fast and accurate analysis of antibody primary structure, thus ensuring the sequencing accuracy of each antibody.
Antibody Modification Services	Immunological testing usually involves the modification of antibodies. Our scientists can provide high-quality antibody labeling services, including fluorescent molecular markers (FITC, FAM, etc.), vector coupling (agarose beads, magnetic bead coupling, etc.), enzyme labeling (HRP, AP, etc.).
Antibody & Antigen Binding Kinetics Study	We are able to provide our clients with BIAcore-based antibody affinity verification services for the development of vaccine assays that can be used to assess the immunogenicity of antigens in animals in vitro. In addition, it can solve the problem of difficulty in selecting different antibodies against the same antigen in the process of vaccine development and the determination of antibody affinity in the rapid detection method.
