We are very proud of Andrew, Ben, and Jacob for publishing their method for fluorescent immunostaining of living lymph node tissue. Most available methods to label structures in tissue are intended for samples that have been fixed (i.e. killed). We showed that it is possible to get beautiful and informative images of tissue structure while the tissue is still alive, without perturbing key functions such as T cell activation. Check out their work in the Journal of Immunological Methods or on our Publications page.
