Weekly quizQuestion: What do you see at the numbers in the sensorgram? SPR Database Members of the Georgetown University (Washington D.C.) have made a Surface Plasmon Resonance Database by collecting technical details from Materials and Methods sections of peer reviewed publications. The goal of SPRD is to assist users of SPR technology with future experimental planning and optimization processes. More information can be found at the SPR Database website . GST-capture kit Based on the novel and easy-to-use click coupling immobilization technique, XanTec launches a GST (glutathione S-transferase) capture kit for site-specific immobilization of GST fusion proteins to be used in SPR assays. More information can be found at the Xantec website ProteOn XPR36 sensors XanTec offers now the sensor chip for the ProteOn XPR36 system from Bio-Rad. Both 2D and 3D hydrogel surfaces are available. More information can be found at the XanTec website COVID-19 research To meet the rapidly increasing demand for COVID-19-related research tools, Forté Bio presents many tools that can be used in your research including how the Octet systems have been used in recent publications. More information can be found at the Forté Bio website.[pause] With regular maintenance your instrument is in perfect order. In addition you make the best, clean and degassed buffers. But what about the proteins you use? Are they of the best quality? And this new batch is the same as the previous, you are sure of that? Is your protein affected by the buffer and immobilization conditions used? Your assay problems might be caused by poor protein quality!Luckily there is an easy and fast way to check the integrity of your proteins. Nanotemper Technologies provides various instruments to check your protein quality, all using a minimum of sample. . Nicoya, a leading provider of advanced analytical instruments for the biotechnology and pharmaceutical industries, today announced the launch of Alto, the world’s first fully-automated, high-throughput benchtop surface plasmon resonance (SPR) system. As the first-ever SPR instrument to integrate digital microfluidics (DMF), artificial intelligence (AI), and nanotechnology, Alto provides high quality, label-free interaction analysis. Surface Plasmon Resonance (SPR) seems to be difficult for many people. Judging on the literature many of you are struggling to get nice sensorgrams with easy to fit curves. However, SPR is straightforward when you know what you are doing. Consequently, you have to learn how SPR works, how to perform an experiment and how to analyze it. So what are the key parts of a proper SPR experiment? Ryan Denomme of Nicoya publishes a nice blog about SPR and related topics. For instance about preserving precious sample by optimizing preconcentration and immobilization or what the difference is between SPR and LSPR. Definitely worthwhile to check this blog! In SPR experiments, low responses are preferred over high responses. This is because high responses in general are affected by mass transport and non 1:1 interactions. But how low can you go?This depends in the first place on the instrument you have chosen. The signal should be above the noise level of the baseline. The curves should be easily recognisable and replicates should overlay. SPRpages book The book contains more additional information and figures compared to the SPR-Pages. In addition, the book can serve as a reference next to your SPR machine. By buying this book you directly support the SPRpages. Goto the SPRpages book This well designed program helps you to clean and analyse your sensorgrams in minutes. Reference subtraction, double referencing, DMSO compensation, almost with one mouse click. Version 2c of Scrubber extends the program with kinetic models for simple binding (association and dissociation rates) and a model for mass transport limited binding. The SPR-Simulation program is a standalone application to simulate kinetic interaction curves. The program draws the curves after the input of the kinetic rate constants, the analyte concentration and the association and dissociation times. Other features are the simulation of equilibrium sensorgrams, mass transport, decaying surfaces and plotting an overlay over an imported sensorgram figure. The KD assistant is a small program to assist with the optimization of kinetics runs. The program can calculate the maximal analyte concentration to be used from one manual analyte injection. The input consists of the initial binding rate (slope), the response of the analyte injection and the analyte concentration. The program deals also with the capturing level of the ligand and adjusts the analyte concentration accordingly. Goto Software The SPR-forum is dedicated to the combination between SPR and biomolecular interactions. There are many questions asked and answered so browse through the topics. Feel free to post your questions about the technology, instruments or experimental set-up. The BiaMethodWriter is a program to write the automation methods in a more interactive way. This program uses pop up menus and dialog boxes to define the values of the parameters. Remembering these odd parameters is not necessary any more.It works for the control software with the Biacore 2000/3000. Is not compatabile with the new T200 control software. Your help is appreciated!. Give your feedback about this website, tips for better experiments or report interesting links. Maybe you have nice tips for every body or you can contribute in a more substantial way to the SPR-pages.Check out the forum for questions and answers. Look at the many books, suppliers, machines, software and other links!?Did you look at the FAQ and download pages? You will find a lot of interesting stuff there.
