Negative staining of proteins is a versatile tool for structural biology. The sample preparation protocol is simple: the sample is embedded in a heavy metal stain that gives rise to increased specimen contrast. Thus, negative staining is a very convenient method to assess sample homogeneity, formation of macromolecular complexes, or quality of protein preparation. Conventional…
Chemical chaperones are necessary in protein experiments. From buffers to storage solutions, chemical chaperones silently make proteins happy and soluble. Read this article to appreciate the love that chemical chaperones bathe on your proteins and learn when to use them! A chemical chaperone is a molecule that promotes the favorable interaction of protein with water…
