ChromoTek’s Nanobody helps LMU scientists in their quest to understand a giant protein complex

Posted by Christian Linke-Winnebeck on Sep 20, 2018 3:42:47 PM

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).

GFP- Nanobodies and RFP- Nanobodies conjugated to quantum dots

Posted by Christoph Eckert on Jul 12, 2018 8:39:33 AM

Chromotek’s GFP- binding protein, an anti- GFP Nanobody, is a very small and effective tool for binding and visualizing GFP-tagged proteins. In their recent publication, Modi et al. successfully functionalized quantum dots with the GFP- Nanobody (QD GFP- Nanobody). Thus, they created a small GFP- specific label with a very strong fluorescent signal.

TurboGFP: Properties, Sequence, MW, origin

Posted by Christoph Eckert on Jul 3, 2018 1:23:20 PM

TurboGFP is a bright green fluorescent protein used to study protein function, localization and dynamics in cells. Nanobody based research tools allow reproducible biochemical analysis including mass spectrometry and enzyme activity measurements of TurboGFP fusion proteins.

First Peptide-tag specific Nanobody applied in super resolution microscopy (SRM)

Posted by Klaus Herick on Mar 2, 2018 11:02:00 AM

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®.

On-bead digestion protocol: From immunoprecipitation with nanobodies to MS analysis

Posted by Christoph Eckert on Sep 15, 2017 3:52:48 PM

What makes on-bead digestion favorable?

Just pull down your protein of interest with immobilized nanobodies, also termed VHHs or single domain antibodies. Then follow the on-bead digestion protocol (see below) and submit the digest to your core facility for effective mass spectrometer analysis of (co-) precipitated proteins.

The best anti-GFP antibody for immunoprecipitation: GFP-Trap

Posted by Christoph Eckert on Sep 7, 2017 1:05:34 PM

Life science laboratories apply green fluorescent proteins (GFP) to study protein localization, interaction and dynamics in fluorescence microscopy. Immunoprecipitation (IP), mass spectrometry (MS), co-immunoprecipitation (Co-IP) and/or affinity purification investigate more aspects including posttranslational modifications (PTMs), DNA binding, and protein-protein interaction. Here, we compare two different antibody systems for immunoprecipitation of GFP-fusion proteins: GFP-Trap and anti-GFP IgG antibody

mNeonGreen: A green fluorescent protein that is not a GFP variant

Posted by Christoph Eckert on Jul 19, 2017 8:20:46 AM

Recently a new bright monomeric yellow-green fluorescent protein has been published, which is called mNeonGreen. This protein has already been frequently used for mainly microscopic applications in both wide-field microscopy and super resolution microscopy. What is mNeonGreen all about?
