September 24, 2016: NEW LINES AVAILABLE! New lines expressed in cardiac, venous, endothelial and smooth muscle systems are now available. Rhodopsin based effectors expressed under control of acta2, HCN4 and αMHC promoters, as well as new GCaMP8 lines expressed under control of αMHC and cdh5 promoters are our latest additions. Visit our mouse production page for more information on these and other upcoming lines.
October 16, 2015: New lines available! We have two new lines ready for distribution. acta2-RCaMP1.07 expresses a red calcium indicator in smooth muscle cells. HCN4-GCaMP8 expresses a green calcium indicator in the SA node and AV node. Additionally, other mice previously created in the Kotlikoff laboratory have been added to CHROMus and can be obtained through Jackson Labs. Visit our mouse production page for more information on these and other upcoming lines.
January 8, 2015: A new year and great progress is being made. We have founders from 6 transgenic constructs and are now analyzing their expression patterns. We’ve added a lacZ tag to the rhodopsin based constructs to allow for easy detection.
