Jellyfish Green Fluorescent Protein (GFP) and its derivatives are still the most frequently used fluorescent proteins in biomedical research. Recently, additional green fluorescent proteins have been discovered in higher animals such as crustaceans and lancelets. These FPs share a common fold, but diverge widely in their primary sequence. Thus, they require novel, dedicated antibody research tools. Here is an overview about EGFP (the most commonly used GFP derivative), TurboGFP and mNeonGreen.

A collaboration between ChromoTek GmbH and Ludwig-Maximilians-University Munich (Germany) has yielded a novel nanobody that sheds new light on an important protein complex called INO80. This work was recently published in the high-impact journal Nature Structural & Molecular Biology (Knoll et al. 2018).

You may have noticed the recent publication “A peptide tag-specific nanobody enables high-quality labeling for STORM imaging” of Virant et al (2018) in Nature Communications doi: 10.1038/s41467-018-03191-2, where for the first time a peptide-tag specific Nanobody was applied in dSTORM imaging: The authors have described and discussed the performance of a BC2 peptide-tag specific Nanobody to image BC2 peptide tag fusion proteins in super resolution microscopy, i.e. dSTORM. This Blog features that BC2 peptide-tag specific Nanobody, which ChromoTek markets under the names Spot-Label® and Spot-Trap®. In addition, this Blog figures the significantly improved version of the BC2 peptide -tag, which is called Spot-Tag®.
