• Name: Biotin-Ova (323-339)
• Synonyms: Biotin-ISQAVHAAHAEINEAGR-OH
• Brand: Biosynth
• Description: Biotin-Ova (323-339) is the N-ter biotinylated version of Ova (323-339). Biotin-Ova (323-339) can be used in the analysis of antigen-specific T cells. Ovalbumin protein:Ova (323-339) is an epitope of interest of the egg white albumen, which is widely used in allergy research. Ovalbumin is a glycoprotein that is sufficiently large and complex to be mildly immunogenic. Indeed, it has been demonstrated that Ovalbumin contains B-cell epitopes which are recognized by specific IgE antibodies and CD4 T cell epitopes restricted by the MHC I-Ad molecule in mice and by HLA-D molecule in human.Applications of Ova (323-339):Ova (323-339) allows to study bindings of class II MHC-peptide and T-cell activation in PBMCs by ELISPOT assays. In fact, this method quantifies peptide epitope specificity and IFN-γ releasing effector cells. It has been shown that Ova (323-339) was responsible for 25-35% of T-cell response of isolated BALB/c mouse. An investigation has demonstrated that Ova and Ova (323-339) induced similar lung inflammation and a Th2-like dominant immune response in mouse model.Sequence: Biotin-ISQAVHAAHAEINEAGR
