Have you heard of #ANGEL?
Not this 😇, but ALFA Nanobody-Guided Endogenous Labeling #ANGEL - the new approach published by Wang et al. in @natchembio.nature.com Build on our ALFA® System, it enables direct fluorescent readout of #CRISPR knock-ins.

ALFA nanobody-guided endogenous labeling - Nature Chemical Biology
Small peptide tags (like ALFA) cause minimal disruption of proteins, but they typically lack fluorescence, which would enable knockin screening. Now, antigen-stabilizing fluorescent protein-fused nano...
