Caspase cleavage of GFAP produces an assembly-compromised proteolytic fragment that promotes filament aggregation
Brain samples were homogenized in SDS lysis buffer (50 mM, Tris-HCl (pH 7.4), 5 mM EDTA, 2%
(w/v) SDS, 1 mMPefabloc SC (Sigma- Aldrich) and Complete™ Mini protease inhibitor mixture
(Roche Applied Science, Mannheim, Germany) using a Geno/Grinder tissue homogenizer.
Residue change of pyridaben in apple samples during apple cider processing
10mL ethyl acetate was added and the mixture was placed on a Geno/Grinder mechanical
shaker (SPEX SamplePrep, USA) for 5 min at 1200 strokes min -1. A total of 4 g of anhydrous
MgSO 4 and 1 g of NaCl were added and vortexed with an XW-80A Vortex.
Simultaneous determination of residues in pollen and high-fructose corn syrup from eight neonicotinoid insecticides by liquid chromatography–tandem mass
Analyst software version 1.4.1 from AB SCIEX was used for data acquisition andprocessing; 1500 ShaQer from SPEX SamplePrep (Metuchen, NJ, USA) was used formixing samples in the QuEChERS extraction procedure.
Quantitative analysis of neonicotinoid insecticide residues in foods: implication for dietary exposure
The ShaQer 1500 from SPEX SamplePrep (Metuchen, NJ, USA) was usedfor mixing samples in the QuEChERS extraction procedure. The tube was subsequentlyshaken for 30 seconds in ShaQer at 1500 strokes per minute.
Y-chromosomal analysis identifies the skeletal remains of Swiss national hero Jo rgJenatsch (1596 - 1639)
Samples were taken during the exhumation by two experienced researchers, with all
necessary precautions. After UV radiation to decontaminate the surface, the samples were
pulverized with a cryogenic mill (6770 Freezer/Mill®, SPEX SamplePrep).
Proteomic Analysis of Liver in Rats Chronically Exposed to Fluoride
Livers were washed in an ice-cold buffer (100 mM Tris, 1 mM EDTA, 1 mMphenylmethylsulfonyl fluoride (PMSF), pH 7.4), and rapidly frozen in liquid nitrogen. The frozentissue was homogenized in a cryogenic, model 6770 Freezer Mill (Spex, Metuchen, NJ, USA).
Hydrogen Uptake of High-Energy Ball Milled Nickel-Multiwalled Carbon Nanotube Composites
Purified MWCNTs (0.8 g) were mixed with Ni (0.5 g) with size less than 150 μm in an
argon-filled glove box and put in a hardened steel crucible. Milling was carried out in a
high-energy ball mill (SPEX 8000 Mixer) for 8 hrs at room temperature.
A simple approach for superior performance of lithium/sulfur batteries modified with gel polymer electrolyte
Apowder (≥99.5%, Sigma-Aldrich) was added into a 7 mL polyethylene vial, to which was added deionizedwater until 20 approximately 6% solid content, followed by shaking with a stainless steel ball
having a diameter of 5 mm for 2 h on a 5100 Mixer Mill® machine (SPEXCertiPrep).
Katanax® Fusion Fluxer
Quantitative Analysis of FeMo Alloys using Lithium Tetraborate Fusion Technique by X-Ray Fluorescence Spectrometry
Essentially, the fusion procedure consists of heating a mixtureof sample and flux at high temperatures (1273 C for lithium tetraborate) employingan automated fusion equipment (Katanax K2).
Characterization of heavy minerals in the Athabasca oil sands
Ashed solids were prepared into fused beads for X-ray fluorescence (XRF) analysis
using a Katanax™ fuser with a platinum crucible and pan. The fused beads were analyzed with
a Bruker S4 Explorer XRF equipped with a wavelength dispersive spectrometer (WDS).
