Diverse single-stranded nucleic acid binding proteins enable both stable protection and rapid exchange required for biological function by Michael Morse, Ben A. Cashen, Ioulia Rouzina, Mark C. Williams

“…These results are consistent with a general model in which protein oligomers containing multiple binding interfaces switch conformations to adjust protein:NA stoichiometry. These characteristics allow a finite number of proteins to protect long ssNA regions by maximizing protein–ssNA contacts while also providing a pathway with reduced energetic barriers to reorganization and eventual protein displacement when these ssNA regions are diminished.…”

Indocarbocyanine–Indodicarbocyanine (sCy3–sCy5) Absorptive Interactions in Conjugates and DNA Duplexes by Evgeny L. Gulyak, Vladimir A. Brylev, Mikhail Y. Zhitlov, Olga A. Komarova, Alexey V. Ustinov, Ksenia A. Sapozhnikova, Vera A. Alferova, Vladimir A. Korshun, Daniil A. Gvozdev

“…Their high molar absorption coefficients and lack of spectral overlap with biopolymers make them ideal as linker components for rapid assessment of bioconjugate stoichiometry. We recently found that the determination of the sCy3:sCy5 molar ratio in a conjugate from its optical absorption spectrum is not straightforward, as the sCy3:sCy5 absorbance ratio at the maxima tends to be larger than expected. …”
