Check if the same lab product or an alternative is used in the 5 most similar protocols
MVs were isolated from differentiating chondrocytes by differential centrifugation as described earlier.(9 (link)) A drop (5 µL) of each MV solution in Tris-buffered-saline was spotted on freshly cleaved mica substrates (Ted Pella, Redding, CA) and allowed to stand for 5 min. Next, 5 µL of glutaraldehyde solution (8% in H2O, Sigma-Aldrich, St. Louis, MO) was dropped onto the samples. The substrates were stored inside a desiccators at room temperature for 24 h. AFM images of dried samples were recorded in air by means of an 5500 atomic force microscope (Agilent Technologies, Santa Clara, CA) equipped with an open-loop probe working in non-contact (AAC) mode. Silicon-nitride cantilevers having a nominal resonance frequency of ~190 kHz (NanosensorsTM, Neuchatel, Switzerland) were used. Tridimensional AFM images were generated by PicoView software (Agilent Technologies). AFM images were used to gather information about the morphology, height, volume and number of MVs in each sample. AFM phase images were also recorded on samples prepared without the use of glutaraldehyde.

Selected area (electron) diffraction (SAED) and HRTEM images were obtained on a JEM-2100F (JEOL Ltd., Japan). Scanning electron microscopy (SEM) images were obtained from an S-3000 N scanning electron microscope (Tokyo, Japan).

Traditional electrochemical measurements were performed using a CHI-630A (CH Instruments Co.) with a three-electrode system at room temperature.

PZMP3-1 used the XRD pattern to determine the crystal structure present. The angular range of the diffractometer was 5–50° (2θ), the step size was 0.01°, the scan speed was 15°/min, and tube pressure (40 kV) and tube flow (40 mA) were present. Using an SEM (S-4800, Japan), the morphological characteristics of PZMP3-1 were documented. We used the Cressington 208 HR Sputtering Coater with sputtering gold samples. We dissolved the polysaccharides with distilled water and dried the test samples dripping on the mica carrier surface at ambient pressure of 70°C. A 5500 atomic force microscope (Agilent) was used to create the AFM images (30 (link)).

The morphology and biomechanical properties of the YSE2-FAT1shRNA and Colo680N-FAT1shRNA cells and the corresponding controls were detected by AFM, as previously described (19 (link)). Briefly, AFM images were acquired in the tapping mode and in contact mode using Si3N4 tips (NSC19, 0.68 N/m normal spring constant; Schaefer Technologie GmbH, Langen, Germany) and gold-coated tips (CSC 38; Schaefer Technologie GmbH), respectively. AFM measurements were performed in aqueous solution at room temperature, using a 5500 atomic force microscope (Agilent Technologies, Inc., Santa Clara, CA, USA). The spring constants of the cantilevers used for AFM force spectroscopy were ~0.1 N/m. Adhesion and elasticity maps were obtained by recording 16×16 force-distance curves on areas of a given size (2×2 µm), calculating the adhesion force and elasticity modulus for each force curve and displaying these values as gray and colorized scale pixels, respectively. These maps qualitatively and quantitatively demonstrated the viscoelasticity of individual cells at the nanoscale level.

Atomic Force Microscopy Surface Roughness Measurement

Check if the same lab product or an alternative is used in the 5 most similar protocols
Atomic force
microscopy (AFM) measurements were performed with a 5500 Atomic Force
Microscope (Agilent Technologies) using an arrowshaped cantilever
(PointProbe Plus ZEISS Veritekt Microscopes - Contact Mode Low Force
Constant - Reflex Coating (PPP-ZEILR), Nanosensors, tip diameter <
10 nm). All images were recorded in the intermittent contact mode
with constant force. The experiments were performed in a glovebox
with argon flow to minimize contact to air. An area of 5 μm
× 5 μm was chosen for all measurements. For data processing,
the software MountainsSPIP (Digital Surf/Image Metrology) was utilized.
The calculation of the arithmetic mean deviation of the surface roughness
(called average surface roughness, Sa,
for simplicity) was done according to EUR 15178N. The maximal surface
roughness (Sm) is the difference between
the highest and the lowest point on the sample surface within the
region of interest.

For nanocrystal thin films, the
colloidal solutions are purified once more with ethanol, centrifugation,
and redissolving in chloroform. Filtered solutions are dropped on
clean substrates and spin coated to form a single monolayer (approx.
15 nm thickness). Films are soaked for 30 s with TBAI solution in
methanol (20 mg/mL) to remove surface ligands and subsequently spin-washed
three times with pure methanol. For thicker films, the deposition
cycle is repeated on top of a previous layer. The thickness is measured
with an Agilent 5500 Atomic force microscope in tapping mode.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
