Inflammation is involved in many fields including cosmetology, drug discovery (including RNA-based vaccines), and diagnostic index development, as well as being linked to almost every disease such as HIV, cancers, or neurodegenerative diseases. For this reason, analysis of the inflammasome is a major concern. Immunoassays are a classic and affordable method to quantify the corresponding proteins secreted by cells during inflammation. Nevertheless, there are well-known drawbacks and limitations raising key questions about the sensitivity, reproducibility and even the universality of the results. We can’t all use mass spectrometry, but fortunately, ELISA tests and multiplexing have evolved. Let’s discover how much.
As with this painted representation of (surrealist!) DNA, to a certain extent, molecular cloning is an art.
Unfortunately for newcomers, or fortunately for experts, it’s required for many downstream applications including protein production and cell engineering to develop cell-based assays. ORF expression is also a major tool for understanding a protein function via overexpression study.
In short, to develop the potential of cell biology research, it’s often a question of adopting a “smart molecular biology” approach. Along the way though, it’s unlikely that you’ll be able to avoid using cloning vectors and other related molecular cloning tools.
However… luckily, fast and simple cloning is possible! Mainly thanks to the smart kits and systems that I’ll explain more about in this post. And for your complete peace of mind, there are also ORF expression clones…
The innate immune system is the body’s crucial first defense against viral infections and it is dependent upon a group of pattern recognition receptors. cGMP-AMP Synthase (cGAS) responds to the presence of DNA in the cytosol by producing 2’,3’cGAMP. Cyclic GAMP in turn binds to STING leading to TBK1-mediated IRF3 activation and the production of type 1 IFN.
Understanding the STING cell signalling pathway and the role cGAMP plays in a number of important areas, such as infection, cancer, inflammation & senescence, relies on cGAMP measurement. Good news – Arbor Assays have just released a new cGAMP EIA kit, read on to learn more!
