Anti-Drug Antibodies

It is important to evaluate the immunogenicity of biotech products during preclinical studies or clinical trials. Using a custom approach we can develop and validate a specific sandwich ELISA for measuring total and specific immunoglobulins.
During the validation, we evaluate the assay cut-off point, sensitivity, intra-/inter-assay variability and sample stability.

Texcell also assesses the seroneutralization capacity for positive samples, such as using cell-based assays.
