Reading the record for Ifnab from NCBI Gene and Ensembl.Still reading. A first read of a gene can take a while; this page waits up to 115 seconds for it, and its scripts then bring in the page, or a line saying what did not arrive.

Order door
The door to order for Ifnab opens with the record, which decides which product it carries. The order page itself is open now.
HGNC and MANE Select: not available for mouse. HGNC names human genes; MGI is the authority here, and MANE Select is defined for human transcripts only.

14 / Silencing this gene
From Ifnab to a sequence that silences it
The AUMsilence™ platform designs the sequences against the mouse 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.
The median is the middle sample of a tissue, so a gene expressed in a few cells of a mixed tissue reads low here and may still be the one your cell type needs. Nothing on this panel is adjusted or averaged across tissues; each figure is the source's own, and a tissue GTEx did not sample is absent from the chart.

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.

scale
Drawn 5' to 3' from each transcript's exons as placed on the reference assembly; exon 1 is the 5' exon on the transcript's own strand. Exon blocks are to scale with each other; introns are drawn at one fixed width whatever their length, so the map is not to scale along the chromosome. Numbers are exon ranks along the strand; a rank is omitted where the exon is too narrow to carry it.
A window on one transcript
One pixel of the map above stands for several bases, and a block too short to see is drawn wider than its own scale, so the map chooses a region and the sequence here chooses the window. Click an exon on a row of the map, or drag across a row; then set the exact start and end below.
These controls are ready in a moment.
No transcript is chosen.
Once a window is chosen this panel shows its length, its G and C count as a percentage of that length, the letters it is made of, the exons it falls in, whether it crosses a junction, and its antisense strand.

Lengths are spliced lengths, as each source states them. Exon ranks follow the strand: on a minus-strand gene exon 1 has the highest genomic coordinate. Reference assembly for mouse: GRCm39.
