Description

Amino Acid Sequence

Ser-Ile-Ile-Asn-Phe-Glu-Lys-Leu

Application

Ovalbumin (257-264) chicken has been used to trigger T cell activation in immunology studies.

Ovalbumin (257-264) chicken has been used:
• to sensitize mice to generate an asthmatic model
• in the stimulation of splenocytes
• for treating dendritic cells to be used as a positive control in cross-presentation studies

Packaging

1 mg in glass bottle

Biochem/physiol Actions

Ovalbumin (257-264) chicken is an antigenic peptide and triggers immune response. Administration of the ovalbumin peptide in pregnant mice helps in surpassing ear development anomalies.

SIINFEKL is a class I (Kb)-restricted peptide epitope of ovalbumin (OVA); the ovalbumin fragment is presented by the class I MHC molecule, H-2Kb.
