Unwanted Immunogenicity (ADA)
During preclinical studies or clinical trials, it is important to evaluate the immunogenicity of biotech products.
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, sample stability, and so on.
Texcell can also assess the seroneutralization capacity for positive samples.
