Effective for testing lab reagents, equipment, and other lab supplies, which can be read visually for qualitative assessment … WebEGTA might activate the nuclease was that EGTA was removing an inhibitory cation which then allowed Ca2þ to bind to the nuclease. To control for this possibility, we tested the nuclease activity in con-centrations of Ca2þ that were up to 16 fold excess of the EGTA (Fig. 3, lanes 6–8). Under these conditions ... reciever for 16 speakers

WebNuclease SI requires Zn2+ (0.01–1.0 m M) for full activity ( 1, 6, 7 ). Other divalent cations, e.g., Co 2+ and Hg 2+, can replace Zn 2+, but enzyme activity is reduced. Mg 2+ is nonstimulatory at around pH 4. The metal ion requirement of nuclease SI changes at neutral pH, and the nuclease can be activated with Mg 2+ (optimum 20 m M) ( 38 ). reciever dallas cowboys
