DyNAVacS

DyNAVacS facilitates design and optimization of DNA vaccine constructs by providing modules for expression vector selection, codon optimization, CpG motif engineering, sequence signal enhancement, restriction enzyme mapping, primer design, and vector information to improve antigen expression and immunogenicity.

Key Features:

• Expression Vector Selection: Assists selection of suitable expression vectors for delivery and expression of DNA vaccine constructs.
• Codon Optimization: Performs codon optimization to tailor coding sequences to the host's translational machinery for improved gene expression.
• CpG Motif Engineering: Enables engineering of CpG motifs within constructs to stimulate innate immune responses.
• Sequence Signal Enhancement: Incorporates additional sequence signals to improve translation efficiency of the encoded antigen.
• Restriction Enzyme Mapping: Provides restriction enzyme mapping to support precise cloning and DNA sequence manipulation.
• Primer Design: Designs primers spanning user-specified sequences to facilitate PCR amplification and related molecular biology workflows.
• Vector Information: Supplies information on vectors currently used in generation of DNA vaccines to inform construct design choices.

Scientific Applications:

• DNA vaccine development for infectious diseases and cancer: Expedites design and integration of construct features required for DNA vaccines intended for prophylactic or therapeutic applications against infectious diseases and cancer.
• Construct optimization for expression and immunogenicity: Supports optimization of coding sequences and immune-stimulatory motifs (e.g., CpG) to enhance antigen expression and influence immunogenic outcomes, including cell-mediated and humoral responses.

Methodology:

Server-side processing is implemented using Common Gateway Interface (CGI) scripts written in PERL running on an Apache HTTP server.
