How can you use “potassium” in a sentence? Here are some example sentences to help you improve your vocabulary:
025 M potassium acetate, 9 mM calcium chloride-dihydrate, pH to 4.5 with glacial acetic acid) for 8 minutes, rinsed 3× two min/each in (0.
The procedure for the histochemical demonstration of actomyosin ATPase was employed as described by Goth and Samara [ 24 ] . Briefly, fixed sections were washed in rinse solution [18 mM calcium chloride in 100 mM tris (hydroxymethyl) aminomethane (Tris), pH 7.8] for 1 minute, preincubated either in 50 mM potassium acetate in 18 mM calcium chloride at pH 4.35 (for acid-stable myosin ATPase, type I slow twitch muscle fibers), or in 18 mM calcium chloride in 100 mM 2-amino-2-methyl-1-propanol at pH 10.
Cells were harvested in the late-exponential phase of growth by centrifugation and resuspended in 50 mM potassium phosphate buffer (pH 7.0), containing 1 mM dithiothreitol (DTT).
For post-tetanic γ oscillations, the slow depolarizations were mediated by tetanic stimulation-induced GABAergic depolarizing action [ 20 21 22 23 ] . This GABAergic depolarization is attributed to the tetanic stimulation-induced accumulation of intracellular chloride [ 24 ] and extracellular potassium [ 22 ] . For hyperthermic γ oscillations, heating causes a Na +/K +pump failure [ 8 ] , in turn resulting in the accumulation of intracellular Na +and Cl -, as well as extracellular K +, finally causing a slow membrane depolarization.
Resistance to polymyxin B is also imparted by the absence or masking of critical binding sites required for polycation-mediated permeabilization of the outer membrane [ 54 ] . Thus, attachment of polymyxin B to Yersinia enterocolitica is reduced by steric hindrance generated by the size and/or branched shape of the outer core region of its LPS macromolecule [ 55 ] . Additionally, resistance to cationic peptides can be due to cytoplasmic clearance of the antimicrobial peptide by an efflux pump; e.g., Yersinia resistance to polymyxin B caused by the RosA/RosB efflux pump/potassium antiporter [ 56 ] and Neisseria gonorrhoeae resistance to protegrin PG-1 via an energy-dependent efflux system termed mtr [ 57 ] .
