Pancreas tissue was dissected from P0 and P4 animals into fixative (2% glutaraldehyte in 0.1 M Cacodylate buffer (Na(CH3)2AsO2·3H2O), pH7.2), cut into ~1 mm3 sections, and placed at 4 °C overnight. Tissue was washed 3x with 0.1 M Cacodylate buffer, post-fixed with OsO4 in 0.1 M Cacodylate buffer for 30 min and washed three times with 0.1 M Cacodylate buffer. The samples were then dehydrated through 60%, 70%, 80%, 95% ethanol, 100% absolute ethanol (twice), propylene oxide (twice), and were left in propylene oxide/Eponate (1:1) overnight at room temperature in sealed vials. The next day the vials were left open for 2–3 hours to evaporate the propylene oxide. The samples were infiltrated with 100% Eponate and polymerized at ~64 °C for 48 hours. Ultra-thin sections (~70 nm thick) were cut using a Leica Ultra cut UCT ultramicrotome with a diamond knife, picked up on 200 mesh copper EM grids. Grids were stained with 2% uranyl acetate for 10 minutes followed Reynold’s lead citrate staining for 1 minute. Electron microscopy was done on an FEI Tecnai 12 transmission electron microscope equipped with a Gatan Ultrascan 2 K CCD camera.

Nanoparticle Characterization Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Dynamic light scattering (DLS) and ζ potential (ZP) measurements were performed on a Brookhaven 90 Plus/BI-MAS Instrument (Brookhaven Instruments). DLS measurements were obtained by performing 5 runs at 30 s per run, and the ZP values were obtained by measuring 10 runs involving 30 cycles per run. TEM images were obtained with an FEI Tecnai T12 transmission electron microscope at an accelerating voltage of 120 keV, and images were taken with a Gatan Ultrascan 2K CCD camera. NPs dispersed in water at an optimal concentration were drop-cast onto glow-discharged, 300 mesh carbon–Formvar coated grids and allowed to dry before imaging. HPLC analysis was performed by Agilent 1100 Series with UV detector at 220 nm, using a 2.6 μm-C18-100 A° Column and a flow rate of 0.9 mL /min, sample injection volume was 10 μL. Solvents were 0.1% TFA in Water (Solvent A) and 0.1% TFA in Acetonitrile (Solvent B) and the gradient elution method was: 0 min = 75 % Solvent A and 25 % Solvent B, 2 min = 66 % solvent A and 34 % solvent B, 6 min = 39.6 % solvent A and 60.4 % solvent B, 6.01 min to 10 min = 0% solvent A and 100 % solvent B, 10.01 min of 75 % (A) and 25% solvent B. Standard curve was made by measuring the area under PTX peak (at 5 min) at different PTX concentrations.

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.
