Antibody Binding vs. Aptamer Binding The immune system has developed very effective screening methods for eliminating antibodies that bind even weakly to self targets such as serum albumin and IgG. Aptamer selection is done outside the body, on the bench which provides many advantages but implicit… Read More »How We Avoid Self-Recognition with Aptamers
Did you see our poll on LinkedIn? If not, check it out here! Our answer to this poll will be short and sweet: Sugars are molecules that have a generic formula of CnH2nOn. They can be described as polyhydroxy compounds containing one ether bond. Most… Read More »Can Aptamers Bind to Sugar Molecules?
The use of the traditional SELEX method for aptamer development has led to the identification of aptamers that bind to a wide diversity of targets. However, there has been limited success with aptamers in therapeutic and diagnostic applications. A key advantage of aptamer development over… Read More »Announcing The Future of Aptamers: Neomers
The clear winner of our poll on antibody specificity was that antibodies have evolved to ignore HAS/IgG. I struggle with this, as I think it is too simple. Really, the way that antibodies rearrange to detect foreign antigens is open; there are no barriers to… Read More »Why Do Antibodies Perform Better in Matrices than Aptamers?
Designing aptamers for specific targets needs to be done in a way that ensures you are selecting the aptamers that bind to your target while easily getting rid of those sequences that do not. Typically, this is done by immobilizing the target so that aptamers… Read More »How We Avoid Immobilizing Targets with FRELEX
The relationship between structure and function is pretty obvious in a lot of engineering projects. Clearly the same is true for aptamers. The functionality of an aptamer is based entirely on it’s structure. In this series of blogs we are going to reveal how we… Read More »Aptamer Structure Prediction
This blog starts with a portrait of Claude Louis Berthollet (1748 – 1872), who was the first to demonstrate and elaborate on the concept of chemical reversibility. As an aside, it should be noted that he accompanied Napoleon to Egypt and, along with Joseph Fourier,… Read More »How Does Chemical Reversibility Impact Commercial Aptamer Diagnostics
This is the first of several blogs we will share on our new Neomer process. The image above can be compared to a dilemma in traditional aptamer selection: are the aptamers that are enriching the product of the selection process (I would vote for the… Read More »How We Overcome Process Bias with Neomers
The phoenix of mythology arises from the ashes of its predecessor. This seems like a very intriguing phenomena, but strikes me as difficult to control in a commercial application. Yet, we keep getting asked whether this is necessary for aptamers to work. Do aptamers need… Read More »Why We Avoid Denaturation of Aptamers for Commercial Applications
