Only one arm needs to be unique (default is both arms):  
Allow overlapping probes (default is non-overlapping):

Padlock probes

Application Description

Padlock is a method to design probes for in-situ sequencing.

Accepted Input

You need to input Ensembl gene (e.g., ENSG00000232810) or transcript identifiers (e.g., ENST00000700026). For gene identifiers use "gene_id" as attribute and "transcript_id" for transcript identifiers. Gene symbols are currently not supported. Alternatively, you can also input a FASTA sequence with a header like ">Input" followed by the actual sequence. For FASTA input, you need to specify whether the sequence is present in the genome (default) or absent.

Sample Data

The "Show Example" button loads an example reference genome with matching Ensembl gene identifiers.
