Precise introduction of point mutations, deletions, or insertions into your DNA sequence with full sequence verification. HIGHLIGHTS OF SITE-DIRECTED MUTAGENESIS self directed mutagenesis enables precise introduction of specific DNA mutations, including point mutations, insertions, or deletions. It is widely applied in protein functional site studies, enzyme activity optimization, DNA element functional analysis, and gene therapy research. Tsingke provide professional and cost-effective site-directed mutagenesis services, accurately introducing desired mutations into any gene template at any number of sites, significantly enhancing experimental efficiency and reducing research costs. SERVICE DETAILS OF SITE-DIRECTED MUTAGENESIS Length Turnaround time (Calendar Day) Vector Deliverables < 1.5 kb 7-10 Customer-specific (1) 1 tube of lyophilized plasmid DNA (about 1~4 μg/tube); (2) QC files: Sequencing map (.abl file); Target sequence (.seq file); COA Report (elec tronic); (3) Any ...

siRNAs are 21-23 nt duplexes that guide RISC to cleave target mRNA. Tsingke provides conventional and modified siRNA from µg to kg scale. HIGHLIGHTS OF sirna duplex MS molecular weight detection with an error margin of less than 0.1% HPLC purity detection ensures purity levels greater than 90%; A high modification rate is achieved, and stable groups such as Ps, 2-F, 2-OMe, and FAM are incorporated into the siRNA oligonucleotides to ensure suitability for downstream applications. Leverage Tsingke's comprehensive industry chain advantages to provide fast and cost-effective services; Multi-channel synthesizer with μg to kg level synthesis capabilities, synthesizing over 100,000 siRNA oligos annually.
