PlasmidsX is a plasmid editor for iPhone, iPad and Mac. Open your constructs, see them as clear circular and linear maps, read every base with its annotations, and plan restriction digests, all on your device. MAPS AND SEQUENCE • Circular and linear plasmid maps with features, primers and restriction sites. Tap any feature to see its details. • A sequence view with both strands, translations, feature tracks and enzyme sites • Find sequences, select a range by its coordinates and copy exactly what you need ANNOTATE AND ANALYZE • Add, edit, sort and search features and primers • A primer library shared by all your plasmids • Find open reading frames • Restriction analysis with the commercially available enzymes from REBASE, aware of Dam, Dcm and CpG methylation • Digest & Gel: pick enzymes and see the fragments on a virtual agarose gel • Saved versions of every plasmid, so you can go back YOUR LIBRARY • Import GenBank, FASTA, SnapGene (.dna) and ApE files from Files, Mail or any other app • Export FASTA and images of the map and the sequence, or print them • A Home Screen widget with your recent and favorite plasmids • Built for iPhone, iPad and Mac, with keyboard shortcuts, pointer support, Dark Mode, Dynamic Type and VoiceOver PLASMIDSX PRO Viewing, importing, annotating and analyzing are free. A PlasmidsX Pro subscription adds: • Sequence editing: type, paste, cut and delete bases, reverse complement, set the origin • Cloning: restriction and ligation, Gibson Assembly, Golden Gate, Gateway and PCR • Alignment of sequencing reads to your plasmid • BLAST searches and sequence downloads from NCBI • GenBank and SnapGene export PlasmidsX Pro is an auto-renewing subscription, billed monthly or yearly. Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically unless you cancel it at least 24 hours before the end of the current period, and your account is charged for the renewal within the 24 hours before the period ends. You can manage or cancel your subscription in your Apple Account settings. PRIVACY PlasmidsX has no account, no ads and no tracking. Your plasmids stay on your device. Data leaves your device only when you ask: a BLAST search sends your query sequence and contact email to NCBI, and a download from NCBI sends the accession number, your contact email and, if you set one, your NCBI API key.

Japality Primer

Features
Read full description

Japality Primer helps you design PCR primer pairs directly on iPhone and iPad. Paste a DNA sequence or FASTA input, review core sequence metrics, and generate ranked primer candidates with adjustable design constraints. The app is built for fast iteration in molecular biology and bioinformatics workflows. Features: • Paste raw DNA or FASTA sequence input • Automatic sequence cleanup and validation • View sequence length, GC content, approximate melting temperature, and reverse complement • Design local PCR primer pairs on device • Adjust target Tm, product size range, primer length range, and number of returned pairs • Review ranked primer candidates with quality scoring • Use offline demo sequences for quick testing Japality Primer is intended as a research and productivity tool for primer exploration. Results should be reviewed and validated experimentally before laboratory or publication use.
