## What is Plasmids X?

Plasmids X: Your ultimate plasmid editor!

A plasmid is a small circular DNA molecule commonly found in bacteria and some other microorganisms. It exists independently of the organism's chromosomal DNA and can replicate itself within the cell. Scientists frequently use plasmids in genetic engineering and biotechnology, as they are easily manipulated and serve as vehicles for introducing new genes into cells for various purposes including research and the production of useful proteins.

Whether you're an expert researcher or just starting in the world of molecular genetics, Plasmids X allows you to design, create, and analyze plasmids effortlessly.

Key Features:

Create Plasmids: Create plasmids from scratch! Just provide a sequence, in FASTA format or raw sequence, and the app will create a new plasmid and automatically add common DNA features. Alternatively, you can create a new plasmid from smaller DNA fragments from the library embedded in the app (this is a paid feature).

Import Plasmids: Import plasmid sequence and features from .dna and Genbank formatted files.

Edit Plasmids: Editing plasmids could not be easier! This function of the Plasmids X app allows you to add custom DNA features to an existing plasmid.

Powerful Analysis Tools: the Plasmids X app not only allows you to visualize your plasmids, it also enables you to perform critical in silico analysis such as sequence alignment, primer Tm estimation, PCR, and restriction enzyme digestion analysis on your plasmid in seconds! (Some of these are paid features.)

Share and Collaborate: Collaborate with your peers by sharing your plasmids with a tap! 

Whether you're conducting research in molecular biology and genetics or learning the very principles of genetics, the Plasmids X app is here to assist you.

### 1/5 — Horrible

*2024-05-23*

Doesn’t support .dna file and does no let you create a plasmid.

**Developer response:** Thank you for your feedback.  As of version 1.8.5, we support .dna files for importation.

If you need any assistance with the app please reach out to plasmidsapp@gmail.com for support.

### 1/5 — not what it seems

*2024-01-19*

Unfortunately, GenBank format import works very poorly (strips a lot useful information), manual re-annotation and correction are a hassle. Awkward graphics and not a very user-friendly interface.

### 4/5 — Great iPad alternative to SnapGene

*2022-11-14*

Hey, thanks so much for developing a plasmid app for iPad, this is great. My one gripe is that I can’t open files stored in OneDrive, and I need to copy them to be located on my iPad itself. I’d happily pay for this feature as a premium option if it were to become available.

**Developer response:** Thanks for using the app! I am glad that the app has been useful for you. Unfortunately, due to limited resources, I don’t have an immediate plan to add native cloud storage support to the app. You can however effortlessly import plasmids from many cloud storage apps that support iOS Files app integration. Plasmids X has access to the Files app interface for import/export operations.
