A growing team of groundbreaking scientists around the world are now sharing their lab notebooks online
Hello Open World! In this very first post I will give an overview of my current and future research on malaria. I would like to sincerely thank everyone here (particularly Matthieu and Mandeep) for welcoming me so warmly. ABSTRACT: A major challenge for the elimination of malaria is Plasmodium falciparum asymptomatic infections, the hidden infectious Read More …
Purification of proteins for a pull down experiment between XIAP and various type I and type II receptors. XIAP is known to bind to the kinase RIPK2. RIPK2 is one of the few kinase proteins that shows overlap of reactivity to some of the compounds that we’ve been looking at in the context of ALK2 Read More …
To understand what proteins do, scientists often test the consequence their absence has on a cell. A common method uses a cells regulatory machinery to disrupt gene expression with complementary RNA molecules, known as RNA interference. Here I used small interfering RNAs (siRNAs) to deplete NSD3 and test the effect this has on epithelial cell identity in Read More …
In my last post, I developed a low-throughput 19F NMR screening assay against USP5 Zf-UBD, where ligand binding of a ubiquitin peptide was detected by perturbations in the resonance of a fluorinated tryptophan at the binding pocket. I recently screened the first batch of compounds that Ivan Franzoni and Renato Freitas, post-docs at the University Read More …
With previously optimized conditions, the linearity range for HDAC11 was obtained and the Km for the substrate was calculated. The data is posted on Zenodo.
I provide herewith my first post – A short overview of my current projects. Research at the SGC-UNC involves the preparation of active chemical probes for understudied protein kinases with the ultimate goal of designing potent small molecule inhibitors as treatment for diseases such as cancer. Kinases play critical roles in cellular signaling which controls important Read More …
Hello again! In previous posts I talked about how we were using a co-culture system to grow our leukemic cells. Although this is a great way to maintain cells, it can complicate some analyses where we cannot distinguish mouse (stroma) from human (AML) cells. We wanted to determine H3K27me3 levels (the mark that EZH2 is Read More …
In nanoBRET assay, a fluorescently labelled tracer binds to the ATP-binding pocket of ACVR1/ALK2. This binding brings the tracer into the proximity (<10nm) of Nano-Luciferase which is fused to the C-terminus of ACVR1/ALK2. Bioluminescence resonance energy transfer (BRET) occurs where the energy released by Nano-Luciferase is transferred to the fluorophore via intermolecular forces. Nano-Luciferase and Read More …
The experimental set-up and results covered in this post can be found here: 10.5281/zenodo.1253365. Recently, I helped run some Western blots for Rachel Harding, a fellow postdoc and open notebooker at SGC (read more about her work here: http://labscribbles.com/), for a publication on a toolkit to enable people to more easily purify and study HTT (you Read More …
After the disappointment of looking through ~13000 crystal drop images over the past couple of weeks and finding pretty much nothing in most of them and nothing that actually diffracted nicely in the rest, it was incredibly heartwarming and hugely inspiring to attend the FOP family and friends conference in Manchester last weekend. FOP Friends is Read More …
