Custom gRNA Libraries in Precision Animal Breeding
BioVenic develops specialized gRNA libraries for farmed animals, covering genome-wide gene knockout gRNA libraries, transcription activation gRNA libraries, and custom pathway-focused gRNA libraries for particular metabolic pathways. Thanks to broadly distributed PAM sequences across genomes, gRNA libraries derived from gene editing technology have become a vital driving force for identifying critical gene functions, uncovering the pathogenesis of livestock diseases, and investigating complex metabolic networks. These resources support efficient, high-throughput screening of functional genes on a genome-wide scale. We further offer flexible customization of animal gRNA libraries targeting designated metabolic pathways to satisfy diverse project requirements from researchers in animal breeding and veterinary research.

Published work demonstrated the complete construction workflow for a porcine‑derived pooled guide‑RNA library for transcription factor screening. The procedure spans library design, pooled‑oligo synthesis, vector cloning, next‑generation sequencing quality assessment, and final lentivirus packaging. Four guide sequences were allocated for each target transcription factor, with target sites distributed across the upstream promoter region of transcription start sites. Sequencing evaluation confirmed full library coverage and relatively uniform read‑count distribution for individual guide components before cellular screening applications.
Drawing on such custom guide‑RNA library construction experiences, BioVenic carries out broad‑scale exploration of relevant technical solutions for precision animal breeding.

Frequently Asked Questions
What types of guide RNA libraries can you customize for livestock research?
We provide three major library solutions tailored to farm animals: genome-wide gene knockout libraries for loss-of-function screening, transcription activation libraries for gain-of-function phenotype research, and targeted pathway libraries focusing on specific metabolic or disease-related gene sets. Each gene is matched with multiple optimized guide sequences to guarantee editing success rates.
What complete service workflow is covered in your guide RNA library project?
Our full one-stop pipeline includes target guide sequence design, vector construction and mixed library amplification, plasmid extraction and purification, optional viral packaging (adenovirus/AAV/lentivirus for cellular delivery), and post-library screening supported by PCR and next-generation sequencing quality verification.
What viral delivery systems do you support for guide RNA library cell transduction?
We offer customized packaging services for multiple recombinant viral vectors including adenovirus, adeno-associated virus and lentivirus. Our precise preparation process ensures each viral particle carries only one unique guide RNA construct, supporting uniform high-throughput screening in animal cell models.
What research applications can guide RNA library screening support in precision breeding?
High-throughput library screening helps researchers identify key functional genes governing livestock growth traits, disease susceptibility and metabolic pathways. Knockout libraries generate loss-of-function mutants while activation libraries uncover genes that boost advantageous production phenotypes for new germplasm development.
How do you guarantee the integrity and quality of finished guide RNA libraries?
We adopt standardized design rules to select high-efficiency guide sequences, conduct strict quality control during vector amplification and purification, and deliver full NGS sequencing validation reports. The sequencing inspection confirms library diversity, uniform sequence abundance and eliminates invalid guide constructs for reliable screening results.
