First published:September 21, 2022
Our ability to study microcirculation longitudinally is restricted by the short in vivo life of injectable fluorescent dyes. Wang et al. describe a method that enables longitudinal visualization of blood plasma in mice after a single injection of AAV viruses, expressing fluorescent secretory albumin-fusion proteins in the liver.

Hall et al. demonstrate luminescence reporter expression from transfected mRNA in the regenerative planarian flatworm Schmidtea mediterranea. This study paves the way for developing additional transgenic techniques in planarians and provides a means to investigate post-transcriptional regulation of gene expression in this previously genetically intractable organism.

Engineered fast-dissociating antibody fragments for multiplexed super-resolution microscopy

First published:September 20, 2022
Zhang et al. establish a versatile mutagenesis strategy to efficiently increase the dissociation rate of antibodies without compromising binding specificity. Engineered fast-dissociating antibody fragments enable high-density IRIS multiplexed super-resolution imaging, which overcomes the intrinsic sparse labeling problem caused by spatial interference between multiple antibodies in other super-resolution approaches.

First published:September 20, 2022
de Kraker et al. present SpecSeg, a user-friendly and versatile open-source toolbox for calcium imaging data acquired with miniscopes or multi-photon microscopes. It selects regions of interest (ROIs) around neurons and neurites, performs neuropil correction and signal extraction, and matches ROIs in sequential recordings.
