14 Silencing this gene

From SPANXC to a sequence that silences it

The AUMsilence platform designs the sequences against the human transcripts on this page. Six decisions are yours before it does. What is written under each is AUM's guidance; the timings and the concentrations are in the usage guide below.

01
Choose the region
A knockdown oligonucleotide can sit in the 5' untranslated region, the coding sequence or the 3' untranslated region, and all three are used. The coding sequence and the 3' untranslated region are the usual first choices for an RNase H design; the 5' end near the start codon suits a steric block. The map above shows where each region sits on the isoforms it draws.
02
Cover the isoforms you mean
An exon every isoform carries silences the whole gene; an exon only some isoforms carry silences those and spares the rest. Decide which you want before a sequence is chosen, and check the reference transcript (MANE Select in human; RefSeq Select and Ensembl canonical in mouse and rat) is the one your cells express.
03
Think across species early
The orthologs panel says whether mouse and rat carry the same gene. Whether one oligonucleotide can serve two species is a sequence question, settled at design by matching the candidate against each transcript, not by the protein identity shown there.
04
Check expression in your model
A transcript that is not expressed in your cells cannot show knockdown. Confirm the gene is expressed in the cell type and condition you will use, from your own data or a reference atlas, before the order. The expression panel above gives GTEx's median per tissue for a human gene; for mouse and rat it says that no atlas is on this page yet.
05
Run the controls
A scramble control of the same chemistry, a positive control against a gene known to knock down in your cells, untreated cells, and a mock condition where a transfection reagent is used. Read knockdown at the RNA level first, then at the protein; the usage guide gives the timing and the concentrations to start from.
06
Pick the product
AUMsilence sdASO needs no transfection reagent and works in the cells that resist one. AUMsilence toASO is the transfection-optimised version of the same design, and AUMsiRNA is the siRNA route. The selection guide compares them.
