Direct Peptide Reactivity Assay (DPRA) test for skin sensitization

In Chemico skin sensitization assay Direct Peptide Reactivity Assay test is becoming the gold standard test in cosmetic applications for skin sensitization testing.The DPRA test is part of the OECD guideline n°442 and is used to determine the sensitizing potential of...

Vaccine development

VACCINE DEVELOPMENT   Immunogenic epitope sequences need to be identified. This is why peptide libraries are used for vaccine development, they allow the peptide sequences of an antigen to be screened in order to better understand the immunogenic character of...

« Solubility test included »

Peptides are delivered as powder. Solubilization conditions depend on the properties of sequences and can be quite well predicted (c.f. link below). Nevertheless it is not an exact science and a real solubility test remains the best approach to avoid losing a sample....
