Abstract:

The associative behaviour of bovine liver glutamate dehydrogenase has been studied by gel chromatography at neutral pH in 1 ᴍ guanidinium chloride and 1 ᴍ sodium chloride. In guanidinium chloride both the elution volume and the elution profile of the enzyme are independent of protein concentration, whereas in sodium chloride they are strongly dependent on it. In NaCl the enzyme behaves as expected according to the well established random association model, whereas in guanidinium chloride it appears to have completely lost the self-associative property. Furthermore, since the elution volume of

Abstract:

Recombinant pig growth hormone (rPGH) was solubilized from inclusion bodies by using the cationic surfactant cetyltrimethylammonium chloride (CTAC). The solubilizing action of CTAC appeared to be dependent on the presence of a positively charged head group, as a non-charged variant was inactive. Relatively low concentrations of CTAC were required for rapid solubilization, and protein-bound CTAC was easily removed by ion-exchange chromatography. Compared with solubilization and recovery of rPGH from inclusion bodies with 7.5 M-urea and 6 M-guanidinium chloride, the relative efficiency of solubi

Abstract:

The secondary structure of recombinant streptococcal Protein G' was predicted and compared with spectropolarimetric data. The predicted secondary structure consisted of 37 +/- 4% alpha-helix and 30 +/- 5% beta-sheet, whereas the values obtained from c.d. data were 29 +/- 2% alpha-helix and 41 +/- 3% beta-sheet. An alpha-helix-beta-sheet/turn-alpha-helix motif is conjectured to comprise the Fc-binding unit. The c.d. spectra in the near u.v. and far u.v. show that the Protein G' molecule is stable to heating at 100 degrees C and to extremes of pH (pH 1.5 to 11.0). The protein retained biological

AbstractA series of guanidinium chloride derivatives have been synthesized by condensation of 1,3-diaminoguanidine monohydrochloride with heteroaromatic formaldehydes in good yields. All compounds were characterized by nuclear magnetic resonances and infrared spectroscopies, and the molecular structures of four compounds were determined by single crystal X-ray diffraction. The optical properties of these guanidinium chloride derivatives with fluoride anions were investigated, showing selective color changes from colorless to yellow or orange, red-shifted in the ultraviolet/visible absorption s

Abstract:

Trimethylamine-N-oxide (TMAO) and guanidinium chloride (GdmCl) are both highly studied molecules in the field of protein folding/unfolding. Thermodynamic studies have shown that TMAO, an organic osmolyte, is a strong stabilizer of the protein folded state, while GdmCl is known to be one of the most effective protein denaturants. Although TMAO and GdmCl are well studied the mechanism by which they stabilize and denature proteins, respectively, is not well understood. In fact there are few studies looking at their effects on hydrophobic interactions. In this work we determine the effect of TMAO

Abstract:

The preparation of intact ribonucleic acid is difficult because of the action of nucleases, which are liberated upon tissue homogenisation. In many cells, high concentrations of the ribonucleases are reserved in the secretory granules and upon disruption of the cell, they get mixed with the RNA and lead to its degradation. Guanidinium chloride and thiocyanate are potent chaotropic agents that reduce hydrophobic interactions and disrupt protein tertiary structures, disassociate proteinnucleic acid complexes and disintegrate cellular structures. Guanidinium thiocyanate is especially strong protein denaturant because both the cation and anion disrupt the hydrophobic bonds between the amino acid side chains. RNA usually binds to proteins within a cell and this agent disassociates the nucleoprotein complex, without disrupting RNA structure. Thus RNA can be obtained by using these agents, after homogenisation and low-speed centrifugation and precipitated with ethanol. The protocol below explains the stepwise isolation of total RNA from cells and tissues using TRIzol reagent which is the mono-phasic solution of phenol and guanidine thiocyanate.
