Peptide-based Cancer Vaccine Development Services

Welcome to Alfa Cytology, your trusted partner in the quest for innovative cancer therapies. Our peptide-based cancer vaccine development services represent a cutting-edge approach to cancer treatment, harnessing the power of peptides to stimulate targeted immune responses against cancer cells. With a focus on precision and efficacy, we strive to revolutionize cancer therapy through personalized vaccine solutions.

Overview of Peptide-based Cancer Vaccine

Peptide-based cancer vaccines employ tumor antigen epitopes but face limited immunogenicity. Adjuvants boost immune responses. These vaccines elicit focused immune responses, targeting key epitopes (immunodominance). Both CD8+ and CD4+ T cell epitopes are needed for activating cytotoxic T lymphocytes (CTLs) and helper T cells. Peptide length impacts vaccine efficacy, with short peptides as minimal CD8+ T cell epitopes, often inducing CTL tolerance. Longer peptides cover more HLA types, fostering sustained, potent anti-tumor responses.

The production of peptide-based vaccines involves various expression platforms, including Escherichia coli (E. coli), plants, yeasts, insect cells, and mammalian cells. Each platform has its advantages and limitations, with mammalian cell-expressed proteins closely resembling natural tumor antigens. Moreover, the fusion of small antigens with carrier proteins, such as heat shock proteins (HSP) and keyhole limpet hemocyanin (KLH), can enhance immunogenicity
