Traditional lentiviral systems, derived from HIV-1, excel in gene delivery. However, their native envelope proteins limit their infection range and stability in serum. Pseudotyping involves molecular substitution to combine the lentiviral core with envelope proteins from various viruses, yielding engineered particles with enhanced stability, targeted tropism, and efficient transduction. Key Advantages of Pseudotyped LentivirusesSafety: Non-replicative, suitable for BSL-2 laboratory environments.Payload Capacity: Capable of delivering large gene sequences (approximately 8kb).Broad Tropism: Effectively infects a wide range of dividing and non-dividing cells.Long-term Expression: Provides persistent expression through genomic integration.Creative Biogene’s Service OfferingsProfessional Consultation and Strategy DesignAnalysis of Target Requirements: Evaluating target cell types and receptor expression.Envelope Protein Recommendations: Suggesting the most suitable envelope proteins from a library of over 50 options.Parameter Optimization: Custom strategies for envelope protein modification.Vector System Planning: Selecting the appropriate lentiviral backbone based on specific research needs.
