Ionic Strength Dependence of Formation Constants, Protonation and Complexation of Asparagine with Thallium (I)
Poster Feb 13, 2007
Mehdi Vadi and Zolikha Zare
The stability constants of the complexes between thallium(I) ion and L-asparagine were determined potentiometrically at various ionic strengths of I=0.1, 0.3, 0.5, 0.7 and 0.9 mol.dm-3 and 20°C. The sodium perchlorate solution was used to maintain the ionic strength. The parameters based on these formation constants were calculated and the dependence of protonation and the stability constants on ionic strength are described by a Debye-Huckel type equation.
We utilized paired synthetic crRNAs coupled with our synthetic tracrRNA in cells transduced with lentiviral Cas9 to perform a functional knockout on hsa-miR-221. This three-part system (crRNA, tracrRNA and Cas9) has demonstrated efficient gene editing when used with only one guide RNA, but the goal was to use two crRNAs to remove the entire stem-loop.READ MORE
