GFP -Trap® - use your fluorescence fusion as tag for biochemical studies.Curiously GFP, the most widely used labeling tag in cell biology, is rarely used for biochemical analyses. This may be due in part to limited GFP antibody availability and specificity as well as co-eluted heavy and light antibody chains that interfere with subsequent analyses.Our GFP-Trap® is a high quality GFP-binding protein coupled to a monovalent matr…
RFP -Trap® - use your fluorescence fusion as tag for biochemical studies Curiously RFP, a widely used labeling tag in cell biology, is rarely used for biochemical analyses. This may be due in part to limited RFP antibody availability and specificity as well as co-eluted heavy and light antibody chains that interfere with subsequent analyses. Superior results in a fraction of the time The ChromoTek RFP-Trap® overcomes these pro…
GFP/RFP-Booster – enhance your fluorescent fusion protein ChromoTek’s Booster are very small, highly specific GFP- or RFP-binding proteins covalently coupled to the superior fluorescent dyes from ATTO-TEC. With our Booster you can: • Reactivate • Boost • Stabilize the signals of your fusion proteinsDirectly stain your protein of interest in fixed cells and benefit from the high specificity an small size that are perfect for su…
Chromobodies® - Your perfect reagents for cellular research including High-Content Analysis. Chromobodies are fluorescent nanoprobes suitable for real time analyses of endogenous cellular structures and processes in live cells. Chromobodies® are a novel species of extremely small intracellular antibodies. They are based on the antigen binding domain (VHH) derived from heavy chain antibodies of camelids genetically fused to a f…
Fusion of proteins to Glutathione S-Transferase (GST) of Schistosoma japonicum is a common technique to increase solubility and expression level of a protein. Furthermore, GST-tagged fusion proteins are often used in protein-protein interaction studies. Both approaches require highly specific tools to isolate and detect GST fusion proteins. GST-Trap The GST-Trap is a highly specific and robust GST-binding protein coupled to ma…
DNA methylation was the first epigenetic modification identified and has been intensively studied for more than half a century. By now it is clear that Dnmt1, the major eukaryotic DNA methyltransferase, faithfully maintains genome-wide methylation patterns and plays an essential role in the epigenetic network controlling gene expression and genome stability during development. However, the molecular mechanisms that ultimately…
Proliferating cell nuclear antigen (PCNA) is a homotrimeric ring-shaped protein that encircles DNA and acts as a loading platform for multiple, transiently interacting factors participating in various DNA transactions. PCNA plays a key role in DNA replication, repair, cell cycle regulation, and post-replicative transactions like DNA methylation and chromatin remodeling. All these cellular processes are regulated by a complex n…
Being able to visualize endogenous cellular structures in live cells is key for many high content analyses. The two Chromobodies® of the ChromoTek’s Cell Organelle Toolbox offer a new way to investigate key compartments of the cell non-invasively. Lamin-Chromobody® The new Lamin-Chromobody® is a major breakthrough especially in High-Content Analysis (HCA) as apoptosis assays thus far rely on static endpoint assays. The nucle…
RNA polymerase II features a large carboxyl-terminal repeat domain (CTD) that consists of the consensus heptapeptide Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7. Differential phosphorylation in this CTD orchestrates accessibility for various co-factors of the transcription complex. Using the phosphorylation specific antibodies it is now possible to determine specific phosphorylation states. In addition to phosphorylation specific antib…
F2H®-Kit Basic for effortless imaging of interactions between GFP- and RFP-tagged proteins of interest and domains thereof in live mammalian cells. The Fluorescent Two- Hybrid (F2H®) Technology is a fast and simple way to study protein-protein interactions (PPIs) by conventional fluorescence microscopy. Its direct optical readout is optimal for high-content analysis (HCA) and screening for PPI inhibitors.F2H® Principle: F…
