A promising direction is actually a improvement of SiR-actin/SiRtubulin-like fluorogenic dyes [19] but with low-affinity binding. This would pave the way for tracking native cellular proteins with minimal disturbance of target protein functioning because of transient interactions using a dye and absence of a bulky protein tag. Above all, the versatility concerning target molecules should be improved. Studies ought to concentrate on establishing a a lot more prevalent way of staining protein structures, lipid membranes, or nucleic acids with all the same or a slightly different strategy. Furthermore, the transient tags with enhanced and greater signal-to-noise ratio are needed, so that you can follow the all-natural dynamics of cellular structures with minimal photodamage.Author Contributions: M.M.P., A.S.G., K.A.L. in addition to a.S.M. were involved in writing, evaluation and editing of this article.
