![]() ![]() Freeware products can be used free of charge for both personal and professional (commercial use). Type IIS enzymes, which are used for Golden Gate assembly, can be displayed using a pre-defined enzyme setįreeware programs can be downloaded used free of charge and without any time limitations. In a sequence trace file, the “A” trace can be displayed with stripes to support researchers with color vision disabilities. A SnapGene collection now supports batch edits of multiple files for flipping sequences, importing features or primers, detecting features or primers, performing BLAST searches, and specifying entries in the Description Panel. When importing features from another SnapGene file or detecting common features, the match threshold can be adjusted between 80-100% When adding references to the Description Panel, a variety of reference types are now availableĪdjustable Threshold for Feature Detection: When a SnapGene collection stores related files in the DNA Files, Protein Files, and Miscellaneous Files areas Like features and primers, individual enzymes can now be shown or hidden using check boxes A DNA or protein sequence window can be split to show two different views, or two versions of the same view Enzyme sites and other annotations in a linear map are now allowed to overlap, thereby reducing map height while preserving legibility Updates include an improved layout for linear maps, an optional split view for sequence windows, more versatile controls for enzyme visibility, and links between related folders in different areas of a SnapGene collection. Also referral discount codes have been discontinued (hence the strikethrough text above.- Version 5.1 provides enhanced flexibility for displaying and annotating sequences. UPDATE (): SnapGene is changing their licensing scheme (no permanent licenses anymore, only yearly subscription fees). If you are considering to purchase a license, you get a 10% discount when using my email address ( as a discount code. Among them is Addgene, a very useful nonprofit distribution channel for DNA constructs (. ![]() Many companies and labs have started to use SnapGene (many of them based on our recommendations). For example, if you want to isolate an insert that can be excised only with a restriction enzyme that cuts also within your insert as shown in the image: Despite two additional BssHII cuts within the sequence, it is possible to isolate the 1985-bp-long BssHII-SalI fragment. This is exactly the type of work that computers are ideal for! Sometimes, you also want to do a partial digest on purpose. two enzymes, which both cut your DNA at multiple sites. However, this requires manually calculating all possible fragment lengths, which can be quite some work if you have used e.g. Then you get typically a complex pattern, from which you very often can deduce (with some effort), whether your construct is OK or not. This comes in handy when you do an analytical digest and you did not add enough enzyme. However, Snapgene has still not implemented a feature that we would like to have: partial restriction enzyme digests. The program is able to read all files within that folder and you can perform actions on the collection (e.g. Support for collections: A collection is simply a folder with SnapGene files.However, I can see that this would be useful for wet lab scientists who quickly want to get some work done without spending hours on writing a Biopython script or learning the syntax of EMBOSS commands. For me, this feature is not essential since I do most of my protein sequence work with BioPython or EMBOSS. SnapGene focuses on implementing features fast and the documentation often lags behind. Support for protein sequences: This is still experimental and many options are grayed out (at least on my version).I tried it out and it's fairly easy to deploy. If you want to publish your constructs online, this would be a nice way to go. Since I last wrote about the SnapGene software ( ), many good things have happened: Snapgene is a software for the wet lab molecular biologist, who does lots of cloning work (construct design and annotation). ![]()
