Explore gene expression levels in different mouse and human immune system cells. Start by entering a gene name (or alias) in the search bar to see a list of hits you can swipe through. Searching will display a "heatmap barcode" that shows how hot or cold expression of that gene is across different immune system cell lineages (B cells, T cells, Myeloid cells, etc). Toggle between 3 different datasets: mouse RNA-seq, mouse microarray, and human RNA-seq. Press down on a cell lineage icon to see the same expression data visualized as a bar chart. Use the settings menu in the top right to toggle between a log and linear axis. In the microarray data, low expression values are partially occluded. Back on the main "heatmap barcode" screen, if you instead press the "Show related genes" button, you'll see a "gene constellation" view. This shows its most correlated genes within certain population groups. By default, correlation is shown with respect to key populations — these are key populations across the entire immune system. Please reach out to immgen@gmail.com for feedback or feature requests! The data are generated by the Immunological Genome Project, an international consortium supported by the National Institutes of Health (NIAID). ## Key features - Gene expression heatmap barcodes - Visualize expression in cell lineages - Toggle between mouse/human datasets - Bar chart visualization - Gene constellation view - View correlated genes ## Recent user reviews (10 of 12) All indexed reviews: https://appshunter.io/ios/app/immgen/id378703882/reviews.md ### 5/5 — Crashes on latest OS *2018-10-09, version 2.4.0* Great app! But crashes and won’t open on new OS. ### 5/5 — Essential App for Immunologists *2017-08-28, version 2.4.0* Outstanding app. The ImmGen app is extremely useful at talks and meetings. Thanks for the update. Pleased to see that the app is still under active development. ### 5/5 — A must have for immunologist *2017-07-19, version 2.3.2* Great resource! ### 5/5 — Crash problem *2014-12-23, version 2.3.1* I also have a problem with the app crashing on an iPhone5S with iOS8.1.2. Haven't had this problem with previous iOS versions. Fantastic app that I use all the time so please fix ASAP! ### 5/5 — Crash with iOS8.02 *2014-12-17, version 2.3.1* Great app - Crashes with iOS8.02- doesn't even load Please Fix😥 ### 5/5 — Super handy! *2014-10-24* Really useful for looking up all those cell markers... ### 4/5 — Fixed *2013-01-02, version 2.2* I loved this app but It doesn't work anymore. No matter what I search for, it never finds anything. Edit: deleting and reinstalling fixes the search problem. It hasn't yet been updated for iPhone 5, but at least it works. ### 1/5 — Use to work *2012-05-07, version 2.0* This app use to be great now cannot find anything. Please fix! ### 1/5 — Doesn't work *2012-02-08, version 2.0* Where do we send feedback? I always get no hits even with "CD4" ### 5/5 — Fantastic *2012-02-01, version 2.0* Fantastic ## Frequently asked questions about ImmGen ### What kind of data does ImmGen show? ImmGen displays gene expression levels in different mouse and human immune system cells. It allows users to explore data from mouse RNA-seq, mouse microarray, and human RNA-seq datasets. ### How can I find gene expression information in ImmGen? You can find gene expression information by entering a gene name or alias into the search bar. This will bring up a list of hits and a heatmap barcode showing expression across various immune cell lineages. ### What are the different visualization options in ImmGen? ImmGen offers a "heatmap barcode" to show expression across cell lineages, and users can press on cell lineage icons to see the same data as a bar chart. It also provides a "gene constellation" view to show correlated genes. ### Can I adjust the axis display in ImmGen? Yes, you can toggle between a log and linear axis for expression data in the settings menu. Note that in the microarray data, low expression values may be partially occluded. ### What is the "gene constellation" view in ImmGen? The "gene constellation" view in ImmGen displays genes that are most correlated with the searched gene within specific population groups. This helps in understanding relationships between genes in the immune system. ### Is ImmGen available on multiple devices? ImmGen is supported on iPhone, iPad, and iPod devices. It is developed by Christophe Benoist and was last updated on July 4, 2023. ### What is the age rating for ImmGen? ImmGen has an age rating of 12+. This suggests it is suitable for users aged 12 and older, likely due to the scientific nature of the content. ### Does ImmGen have ads? No, ImmGen does not contain advertisements. It is a free application with no in-app purchases, focusing solely on providing gene expression data. ## Version history (last 5 releases) ### 3.2.0 — 2023-07-04 - New human RNA-seq data - Various small improvements ### 3.1.0 — 2022-12-08 - New RNAseq cell types - Updated RNAseq data ### 3.0.0 — 2022-12-08 - Added RNAseq dataset - Added "gene constellation" view for RNAseq data - Updated UI for a more modern feel ### 2.5.0 — 2018-10-11 - Updated to be compatible with iOS 12 ### 2.4.0 — 2017-08-27 - The FAMILY functionality has been restored. Tap the Family button to see which GO terms apply to your current gene. From there, you can tap blue GO terms to see all genes with that classification. - Still expect a few bugs using the population comparison. ## Related topics [aaaai](https://appshunter.io/ios/topics/aaaai) · [cytokine](https://appshunter.io/ios/topics/cytokine) · [bwslots](https://appshunter.io/ios/topics/bwslots) · [43 cnot](https://appshunter.io/ios/topics/43-cnot) · [immunitates](https://appshunter.io/ios/topics/immunitates) · [aai immunology](https://appshunter.io/ios/topics/aai-immunology) · [icommune](https://appshunter.io/ios/topics/icommune) · [blot interactive](https://appshunter.io/ios/topics/blot-interactive) · [snp tcpilotage](https://appshunter.io/ios/topics/snp-tcpilotage) · [qpcr](https://appshunter.io/ios/topics/qpcr) · [biocoded](https://appshunter.io/ios/topics/biocoded) · [aSMA gene name](https://appshunter.io/ios/topics/asma-gene-name) · [chronic lymphocytic leukemia](https://appshunter.io/ios/topics/chronic-lymphocytic-leukemia) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
