| Application: | Ovalbumin has been used: • as a medium for cell incubation in EliCell assay for the detection of released cytokines from eosinophil • to induce allergic inflammation and atopic dermatitis in experimental mice • as a component in control mixture for validating tandem mass spectral analysis • as a model protein antigen to evaluate the in vivo efficacy of a chitosan/interleukin (IL)-12 adjuvant system |
| Biochem/physiol Actions: | Albumin from chicken egg white serves as a natural adhesive. |
| Biochem/physiol Actions: | Differential scanning calorimetry indicates that chicken egg albumin denatures at 84 °C. Ovalbumin can be used as a carrier protein to conjugate to synthetic peptides for use as an immunogen. It has the following amino acids: 20 Lys, 10 Tyr, 6 Cys, 14 Asp, and 33 Glu which make it suitable for conjugation. |
