Pre-Designed siRNA Sets
GenCefe Biotech provides you with effective gene silencing tools! Our experienced design team has pre-designed over 50,000 siRNA sets for human, mouse, and rat, ensuring a gene silencing efficiency of over 70%.
New customers enjoy 20% off on first order!
Each set includes 3 individual siRNAs (6 nmol each) and comes with free control siRNAs.
Fast turnaround, starting from just 4 days!
3 individual siRNA: 6 nmol/siRNA
Positive Control, Negative Control, FAM-NC: 3 nmol/each
4 individual siRNA: 12 nmol/siRNA
Positive Control, Negative Control, FAM-NC: 3 nmol/each
We guarantee that when the cell transfection efficiency is > 80%, at least one pair of siRNA can achieve a silencing effect of > 70%. Otherwise, 2 pairs of siRNA will be re-synthesized for free after comprehensive analysis.

“We availed gene synthesis services form Gencefe for constructs of our propriety mammalian expression vectors and it matched 100% sequence we provided. Successfully we expressed several proteins and antibodies using the vectors we received from Gencefe.
In another instance, we were trying to clones chimeric protein gene and were facing challenges due to multiple G4S linkers, here again we availed the services of Gencefe, they have codon optimized the sequence, synthesized and cloned in pET21 a vector, we expressed the protein and expression was pretty high.
Based on the experience, I recommended few of friends in Industry and they also expressed satisfaction with their services, I hope the Gencefe maintain same quality and good services in future too”
