Viral Vector Constructs & Packaging 

Cellecta provides expertly engineered lentiviral, retroviral, and AAV vectors to support genetic engineering, functional genomics, and screening studies. Backed by over 18 years of experience, hundreds of successful custom projects, and more than 600 peer-reviewed publications, our vector constructs and packaging services have been used by many of the leading academic, biotech, and pharmaceutical researchers worldwide.

Ideal for a Range of Applications

  • Stable cell line development
  • Functional genomics and CRISPR screening
  • Inducible gene activation and repression
  • Gene knockdown and RNAi studies
  • Pathway analysis and reporter assays
  • Stem cell and immune cell engineering
  • Antibody or CAR construct delivery
  • Difficult-to-transfect cell types (e.g., primary or suspension cells)

Extensive Vector Catalog & Custom Construct Services

  • Diverse backbones for expression of sgRNA, shRNA, and cDNA
  • Custom sgRNA and shRNA constructs targeting any genetic elements
  • Verified vector designs, plasmid prep, sequencing confirmation, and functional titering
  • CRISPR sgRNA-only, all-in-one, dual-guide, and inducible formats
  • Variety of fluorescent and antibiotic selection markers, as well as vector barcoding
  • Pre-made sgRNA and shRNA non-targeting, non-specific, and lethal controls
  • Validated vector designs based on years of in-house and published use

High-Quality Functional Lentiviral Packaging Services

  • VSV-G pseudotyped particles for broad cell-type transduction
  • Functionally titered virus—based on actual transduction (not p24 or DNA copy number)
  • Obtain defined numbers of functionally titered viral particles to ensure effectiveness
  • Clean viral concentration with LentiFuge™ Viral Concentration Reagent—outperforms PEG
