Gene Universal

Gene Universal now offers high-quality, sequence-verified single-stranded DNA (ssDNA), ideal for maximizing the editing efficiency of your CRISPR-mediated gene knock-in, in-vitro transcription, and other experiments. With high editing efficiency and lower off-target integration, ssDNA is considered the optimal CRISPR Homology Directed Repair (HDR) template for creating gene knock-ins to develop transgenic animal models and cell lines.

Advantages of leveraging ssDNA as CRISPR-mediated gene knock-in HDR Templates.

Lower cellular toxicity

Reduced off-target integration

High efficiency

Increased editing accuracy

Applications Of ssDNA Synthesis

1. CRISPR-mediated gene knock-in, replacement, or correction

Double Stranded Breaks (DSBs)

Guide RNA (gRNA)

Protospacer Adjacent Motif (PAM)

Non-Homologous End-joining (NHEJ)

Homology Directed Repair (HDR)

2. In vitro transcription

Transcription initiates DNA-based gene expression, converting DNA segments into RNA, particularly mRNA, through RNA polymerase enzymes. In vitro transcription (IVT) utilizes RNA polymerases (T7, T3, or SP6) and DNA templates to transcribe RNA molecules. Templates for IVT include double-stranded DNA fragments, circular plasmid DNA, and single-stranded donor oligonucleotides (ssODN) or single-stranded single-stranded DNA (ssDNA).

Other application areas
