Description

Ova Peptide (257-264) Tfa is a synthetic peptide fragment derived from ovalbumin, a key protein in egg white. This compound is of significant interest in immunological research and pharmaceutical development due to its role as a defined antigenic epitope. It is primarily utilized by research institutions and biotechnology companies engaged in vaccine development, allergy studies, and fundamental immunological research to investigate T-cell responses and immune modulation mechanisms.

Application

• Immunological Research: As a model antigen for studying T-cell activation, epitope mapping, and immune response pathways in vitro and in vivo.
• Vaccine Development: Used in the research and development of peptide-based vaccines, particularly for studying antigen presentation and efficacy.
• Allergy Studies: Serves as a defined allergen epitope for investigating the mechanisms of egg allergy and developing diagnostic tools or therapeutic interventions.
• Biomarker Research: Employed in assays to detect and quantify specific immune cells responsive to this ovalbumin fragment.
• Pharmaceutical Intermediates: Acts as a key intermediate or reference standard in the synthesis and quality control of more complex immunotherapeutic agents.
• Cell Culture & Assay Development: Used to stimulate immune cells in culture systems for functional assays and high-throughput screening.
