Look, no label! Microscale thermophoresis makes use of the intrinsic fluorescence of proteins to quantify the binding affinities of ligands and discriminate between binding sites. This method is suitable for studying binding interactions of very small amounts of protein in solution. The binding of ligands to iGluR membrane receptors, small-molecule inhibitorss to kinase p38, aptamers to thrombin, and Ca(2+) ions to synaptotagmin was quantified.

Alkaline phosphatase (ALP) is a nonspecific phosphatase, and its interaction with substrates mainly depends on the recognition of phosphate groups on the substrate. Previous enzymatic research has focused mainly on the enzymatic reaction kinetics of the inorganic small molecule p-nitrophenol phosphate (pNPP) as a substrate, but its interaction with biomacromolecule substrates has not been reported. In current scientific research, ALP is often used for molecular cloning, such as removing the 5' termini of nucleic acids.

The COVID-19 pandemic has underscored the urgent need for antiviral agents capable of targeting a broad range of coronaviruses, including emerging variants of SARS-CoV-2. While vaccines have been pivotal, the search for drugs that can prevent viral entry into host cells remains crucial, especially against evolving viral forms and other coronaviruses. In this study, we investigated natural products as a source of antiviral agents, focusing on their potential to block the spike protein's receptor-binding domain (RBD).

Background: A loss-of-functional mutation (W1183R) in human complement factor H (CFH) is associated with complement-associated hemolytic uremic syndrome; mice carrying a similar mutation (W1206R) in CFH also develop thrombotic microangiopathy but its plasma von Willebrand factor (VWF) multimer sizes were dramatically reduced. The mechanism underlying such a dramatic change in plasma VWF multimer distribution in these mice is not fully understood.
Objective And Methods: To determine the VWF and CFH interaction and how CFH proteins affect VWF multimer distribution, we employed recombinant protein expression, purification, and various biochemical and biophysical tools.

The serine/threonine kinase CK2 (formerly known as casein kinase II) plays a crucial role in various CNS disorders and is highly expressed in various types of cancer. Therefore, inhibiting this key kinase could be promising for the treatment of these diseases. The CK2 holoenzyme is formed by the recruitment of two catalytically active CK2α and/or CK2α' subunits by a regulatory CK2β dimer.
