Please feel free to try out our lab’s protocols. The links below will redirect to Google Docs with the relevant protocol.

If you use our methods, please cite our specified publications and any earlier work they build upon. And please don’t create scientific ‘scavenger hunts’ in your Materials and Methods section—describe everything thoroughly so that it can be reproduced!
