O-GlcNAcylation and phosphorylation engage in well-documented signaling crosstalk, sometimes competing for identical or nearby residues on the same substrates33,61,62,63,64,65. None of the NF-L O-GlcNAc sites we identified is a validated phosphosite, but NF-L is known to be phosphorylated at ...
Normally, if the difference in electronegativity is larger than 1.7, then it is more ionic than covalent; equals 1.7, 50% covalent 50% ionic; smaller than 1.7, more covalent than ionic. Thus, you can also use this as a guideline to judge whether a binary compound (like NaCl) is ionic ...
The 384-well format assay coupled with WST/1-mPMS was applied to high-throughput screening and evaluation of compound potency. The Michaelis constant (Km) value was assayed in a buffer at final volume of 40 µL (100 mM HEPES, pH 7.4;100 mM NaCl; 2 mM MgCl2; 0.1 mM DTT; 0.5 mM ...
