...Motoharu Kawano; Jinyeon Hwang Abstract Guanidine and imidazole are important functional molecules that constitute the side chain of basic amino acids (arginine and histidine); these molecules are capable of interacting with mineral surfaces. However, little information is available about...

... assessed three methods of DNA preservation (air-drying, freezing with or without seawater, and Guanidine lysis buffer treatment with or without EDTA (Ethylenediaminetetraacetic acid)). Our study produced the following results: 1) there were no significant differences in DNA preservation when samples were...

...S. E. Kesson; J. R. Holloway Abstract Three fluid compositions in the C-O-H-N system, each with nominal mole fraction of H 2 O = 0.25, were used for comparative determinations of the solidus of synthetic albite at 4.4kbar. The fluids were generated by the decomposition of guanidine nitrate CH 5 N 3...

... the growth of gram-positive bacteria, gram-negative bacteria, fungi, and yeasts (Asadi et al. 2021 ; Peng et al. 2021 ). The guanidine group was easily protonated to be positively charged, so PHMB could be adsorbed on the negatively charged bacterial cell membranes, and then destroy the cell membranes...

..., while in the case of “quartz spheres” some DNA isolates contained more than one specimen. DNA was extracted using either a DNeasy kit (Qiagen) or the guanidine method described by Tkach and Pawlowski (1999) . PCR amplifications were performed on a total volume of 50 μl with an amplification profile...

... were carefully separated and the solid phase was dried at 120 °C. X-ray diffraction and scanning electron microscope examinations showed no evidence of impurities in zircon. Water was converted to CO 2 for the isotopic analyses using guanidine hydrochloride (NH 2 ) 2 CNH*HCI (reagent quality...

... specimens of C. szymborska was extracted using guanidine lysis buffer ( Pawlowski, 2000 ); two extractions were carried out with four specimens each. The DNA isolate numbers and collection sites are given in Table 2 . The PCR amplifications of the SSU and LSU rDNA were performed using several primer...
