The General Introduction of sgRNA Synthesis
CRISPR/Cas9 gene editing technology has revolutionized research across various fields, dramatically enhancing the efficiency of genome editing. Unlike traditional methods the direct delivery of ribonucleoprotein (RNP) complexes, formed by Cas9 and sgRNA, into cells is faster, less immunogenic, and has lower off-target effects while achieving higher editing efficiency.
At Synbio Technologies, we offer expert synthesis services for gene editing researchers. Synbio Technologies provides two sgRNA synthesis strategies: chemical synthesis and in vitro transcription.

Case Study
Our sgRNA Design Center designed 8 sgRNAs per gene for multiple genes in mice and conducted in vitro transcription within 2 days, producing 10-20 μg sgRNAs for rapid use in cytological experiments.
1. The gRNA DNA template was cloned into the pUC57 vector using blunt-end ligated and verified with Sanger sequencing. The comparison results were consistent with the designed sequence. As shown in Figure 1.

2. Electrophoresis in 2% agarose was performed on the sgRNA obtained by in vitro transcription and clear bands could be seen. This is shown in Figure 2.

3.One sgRNA sequence was verified: The selected sgRNA was reverse transcribed to obtain cDNA, sgRNA amplification primers were designed, and the DNA sequence of sgRNA was obtained through PCR. Then the DNA sequence was cloned into the pUC57 vector using blunt-end ligation and verified with Sanger sequencing. The resulting sequencing data verified that the sgRNA sequence was correct. This is shown in Figure 3.

FAQs
How can off-target effects of sgRNA be avoided?
- Using highly specific Cas9 variants.
- Precise design of guide sequences to minimize similarity to non-target sequences.
- Use bioinformatics tools to predict potential off-target sites and optimize them when designing sgRNAs.
How to improve the stability and activity of sgRNA?
The stability and activity of sgRNAs can be improved by chemical modifications (e.g., at the 2'-OH site). In addition, optimizing the design of sgRNAs to reduce off-target effects can also help improve their efficiency.
what things are important to consider when designing a sgRNA?
When designing a sgRNA, consider the target sequence specificity and ensure the presence of a suitable PAM sequence near the target site to minimize off-target effects. Additionally, stabilize the GC content, avoid strong secondary structures, and validate the sgRNA's efficiency and specificity experimentally.
