Microtubule assembly and disassembly at alkaline pH
Although it is now apparent that the intracellular pH may rise considerably above neutrality under physiological conditions, information on the effect of alkaline pH on microtubule assembly and disassembly is still quite fragmentay. We have studied the assembly/disassembly of bovine brain microtubule protein at alkaline pH in vitro. When microtubules are assembled to a new steady state at pH le...
متن کاملMechanisms of somatosensory neuronal sensitivity to alkaline pH.
Life for most species is best in a very narrow range of pH. Departures of tissue pH from this narrow range are guarded against by various neural and physiological defense mechanisms. In the past few years, we have gained a much better understanding of what the sensory bases of the defenses against acid insults are. Specifically, several ion channels (TRPV1, Caterina et al., 1997; ASIC3, Waldman...
متن کاملInteractions of monomolecular films of retinal at alkaline pH.
The surface properties of mixed monomolecular films of retinal and phospholipids were studied at a nitrogen/water interface. The subphase was glycine buffer pH 10.5 with an ionic strength of 0.1. Monomolecular films of retinal in the presence of amino acids were also measured. The area per molecule, at a surface pressure of 10 dyn/cm, A10, in the dark for 9-cis retinal and 11-ci‘s retinal are 4...
متن کاملHemoglobin electrophoresis at alkaline pH on agarose gels.
We describe a modified thin agarose-gel system for use in primary hemoglobin screening by electrophoresis. The system makes use of a Tris-EDTA-borate-buffered agarose gel (pH 8.8) and a sodium barbital electrophoresis buffer (pH 8.6). Separation is effected in 20 min at a constant potential of 250 V. Eight samples can be simultaneously separated and the patterns made visible in 47 min. There ar...
متن کاملOptical pH Sensor Based on Quinizarin for Alkaline pH Regions
The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...
