We have found that Mg++ supports IgM complex binding to mouse lymphocytes but not to macrophages. In contrast, Ca++ supports IgM complex binding to macrophages but not lymphocytes. IgG complex binding to both lymphocytes and macrophages is divalent cation independent. These findings allow one to distinguish IgG from IgM binding and macrophage from lymphocyte IgM complex binding by their differential divalent cation requirements. ...

TY - JOUR. T1 - Effects of divalent cations on voltage-gated Ca2+ channels and depolarization-induced [Ca2+]i transients of freshly isolated pyramidal cells of the rat dorsal cochlear nucleus. AU - Harasztosi, Cs. AU - Rusznák, Z.. AU - Kovács, L.. AU - Szucs, G.. PY - 2001/12/1. Y1 - 2001/12/1. N2 - The effects of divalent cations on voltage-activated Ca2+ channels and depolarization-evoked cytoplasmic [Ca2+] elevations were studied in pyramidal neurones isolated from the dorsal cochlear nucleus of the rat. Ca2+ currents were recorded using the whole-cell configuration of the patch-clamp technique. 10 μmol·1-1 Cd2+ exerted a greater blocking effect on the high-voltage activated (HVA) currents than on the low-voltage activated (LVA) ones (decrease to 26.6 ± 2.5% and to 87.8 ± 2.1%, respectively). The blocking effect of 200 μmol·1-1 Cd2+ was more pronounced and the difference between the effect on the HVA and LVA currents became smaller (decrease to 11.7 ± 2.1% and to 32.4 ± 2.7%, ...
Biological membranes contain as a basic structural unit a phospholipid bilayer. Phospholipid membranes in the form of bilayer films (BLM) are currently used as experimental models for transport phenomena of the biological membranes. In particular, bilayers made of acidic phospholipids, present the advantage to investigate the bioelectrical phenomena across the biological membranes. This class of phospholipids by having a fixed charge might bind ions that play an important role on many physiological processes. It is known that Ca++ and other alkaline cations change the electrostatic potential of the negatively charged bilayer membranes either absorbing to the phospholipids or accumulating in the aqueous diffuse double layer, and this potential change may induce conductance variation (1). Cd++ another divalent cation has been shown to exert influence on the permeability of some anaelectrolytes across BLM made of negatively charged phospholipids, but not on the zwitterionic phospholipids (2). We ...
0-6.0), phosphate (pH 6.0-7.0), Tris-HCl (pH 7.0-9.0), and glycine-NaOH (pH 9.0-10.0) under standard conditions. The pH was adjusted at 50°C. Formation of the transketolase apoform and reconstitution of the holoenzyme Apo-transketolase was obtained by removing the. cofactors THDP and divalent cation through dialysis for 24 hours against Tris-HCl buffer pH 7.5 containing 10 mM EDTA. After removing EDTA NCT-501 price by dialysis, different divalent cations were tested as possible cofactors in the transketolase reaction using Assay I and 1.25 mM X5-P and R5-P, respectively. The effect of metal ions and EDTA, ATP or ADP on TKT activity was measured under standard conditions (Assay I) in the presence of Ca2+, Co2+, Cu2+, Mg2, Mn2+ and Ni2+ at 1 mM final concentration in the reaction mixture. The remaining percentage activities were determined by comparison with no metal ion added. To investigate the effect Trichostatin A cost of EDTA, EDTA salt solution was incubated with TKT for 4 minutes. The ...

Dear, I have a question about medium used in tissue cultruing. Im currently doing functional assays using RPMI 1640 medium, in which ligand binding on cells may occur. I would like to know if I want some divalent cation present in the medium to test the nature of binding, anyone can tell me what chemical compound(s) I should add into the medium to provide the divalent cation, like Ca++? or other kind of medium can be used instead of RPMI. Thank you in advance. Regards Eddie ...

cAMP-gated channels were studied in inside-out membrane patches excised from the apical cellular pole of isolated olfactory receptor cells of the rat. In the absence of divalent cations the dose-response curve of activation of patch current by cAMP had a KM of 4.0 microM at -50 mV and of 2.5 microM at +50 mV. However, addition of 0.2 or 0.5 mM Ca2+ shifted the KM of cAMP reversibly to the higher cAMP concentrations of 33 or 90 microM, respectively, at -50 mV. Among divalent cations, the relative potency for inducing cAMP affinity shifts was: Ca2+ , Sr2+ , Mn2+ , Ba2+ , Mg2+, of which Mg2+ (up to 3 mM) did not shift the KM at all. This potency sequence corresponds closely to that required for the activation of calmodulin. However, the Ca(2+)-sensitivity is lower than expected for a calmodulin-mediated action. Brief (60 s) transient exposure to 3 mM Mg2+, in the absence of other divalent cations, had a protective effect in that following washout of Mg2+, subsequent exposure to 0.2 mM Ca2+ no ...
Divalent cations are important in the folding and stabilization of complex RNA structures. The adenine-sensing riboswitch controls the expression of mRNAs for proteins involved in purine metabolism by directly sensing intracellular adenine levels. Adenine binds with high affinity and specificity to the ligand binding or aptamer domain of the adenine-sensing riboswitch. The X-ray structure of this domain in complex with adenine revealed an intricate RNA-fold consisting of a three-helix junction stabilized by long-range base-pairing interactions and identified five binding sites for hexahydrated Mg2+-ions. Furthermore, a role for Mg2+-ions in the ligand-induced folding of this RNA was suggested. Here, we describe the interaction of divalent cations with the RNA-adenine complex in solution as studied by high-resolution NMR spectroscopy. Paramagnetic line broadening, chemical shift mapping and intermolecular nuclear Overhauser effects (NOEs) indicate the presence of at least three binding sites for ...

Prokaryotic and eukaryotic proteins cluster separately but probably function with the same polarity by similar mechanisms. These proteins are secondary carriers which utilize the pmf and function by H antiport (for metal efflux). One member, CzcD of Bacillus subtilis, has been shown to exchange the divalent cation (Zn2+ or Cd2+ ) for two monovalent cations (K+ and H+ ) in an electroneutral process energized by the transmembrane pH gradient (Guffanti et al., 2002). Another, ZitB of E. coli (TC #2.A.4.1.4), has been reconstituted in proteoliposomes and studied kinetically (Chao and Fu, 2004a). It appears to function by simple Me2+:H antiport with a 1:1 stoichiometry.. Montanini et al (2007) have conducted phylogenetic analysis of CDF family members. Their analysis revealed three major and two minor phylogenetic groups. They suggest that the three major groups segregated according to metal ion specificity: (1) Mn2+ , (2) Fe2+ and Zn2+ as well as other metal ions, and (3) Zn2+ plus other metals, but ...
We have shown that the E172Q and E172C mutations of L247T α7 nicotinic receptors eliminate receptor stimulation by the presence of permeable divalent cations. ACh dose responses of E172Q/L247T α7 nAChRs were inhibited by the presence of Ca2+, Ba2+, or Sr2+, and E172C/L247T α7 nAChRs were insensitive to the presence of these ions. E172Q/L247T α7 nAChRs did not display the high level of basal activity that is a characteristic of L247T α7 receptors and were not activated by the antagonist DHβE. E172C/L247T α7 receptors were blocked by the thiol-modifying reagent MTSET, indicating that E172 is accessible to permeant ions. These data support the conclusion drawn from a chimera of α7 nicotinic receptors and 5-HT3 receptors that E172 is essential for the modulation of α7 receptors by Ca2+ and other permeant divalent cations (19). The data are also consistent with a model of α7 receptors based on the crystal structure of AChBP (6) that places E172 near the inner surface of the vestibule, where ...
