Structural Analysis of MBQ-167 Crystals

Optical microscopy with polarized light was used to evaluate the morphology and crystal quality of the resulting MBQ-167 crystals. Optical micrographs were collected within a Nikon Polarizing Microscope Eclipse LV100N POL, equipped with a Nikon DS-Fi2 camera and NIS Elements BR software (v. 4.30.01). Using a small amount of paratone oil the single crystals for each form were mounted in MiTeGen micro loops. Crystal structures were determined from diffraction data collected using a Rigaku XtaLAB SuperNova single microfocus Cu-Kα radiation (λ = 1.5417 Å) source equipped with a HyPix3000 X-ray detector in transmission mode (50 kV and 1 mA). An Oxford Cryosystems Cryostream 800 cooler was used to collect the data at 300 and 100 K. Data was analyzed using the CrysAlisPRO software (v. 1.171.39.46). All crystal structures of MBQ-167 were solved by direct methods using SHELXS. The refinement was made using full-matrix least squares on F2 within the Olex2 software (v. 1.2). (Dolomanov et al., 2009 (link)) All non-hydrogen atoms were anisotropically refined.

Immunohistochemical Analysis of CLIC1, CLIC4 and CA125

The paraffin embedded TMA slides were deparaffinized by washing in xylene followed by rehydration. Antigens were retrieved by treating the slides with citrate buffer (pH 6.0) and endogenous peroxidase activity was quenched by 3% H2O2. Subsequently the TMAs were incubated with 3% BSA to prevent nonspecific antibody binding. After blocking, the TMAs were incubated with monoclonal antibodies against CLIC1 (1:450, ab77214), CLIC4 (1:100, ab183043) and CA125 (1:250, ab110640) overnight at 4 °C, followed by further incubation with HRP labeled anti-rabbit, anti-mouse or anti-goat secondary antibody as appropriate. TMAs were then treated with di-aminobenzidine, counter stained with Mayer’s hematoxylin, dehydrated and mounted in crystal mount medium. The TMA slides were then subjected to blind, unbiased analyses by co-author RD. The tissue staining was scored as 0, 1, 2 or 3 based on their intensities. 0 was considered negative while 1, 2 and 3 were considered positive. Scoring was performed by an expert pathologist in a blinded manner (RD). Images of tissue cores were obtained using a Nikon DS-Fi2 camera and were analyzed using NIS Elements software (version 4.13).

Thermal Analysis of Fatty Acid-Polyethylene Glycol Mixtures

This method was conducted as previously reported in the literature,17 ,19 (link) using a hot stage (Linkam Scientific Instruments Ltd., LTS 420) coupled with a polarized light microscope (Nikon Eclipse LV100N POL). The physical mixtures (~60 mg) were evenly distributed onto a microscope slide and equilibrated at 20 °C prior to heating (5 °C/min) to 150 °C. Afterward, the molten mixtures were cooled to 25 °C at a rate of 20 or 2 °C/min, for fast- and slow-cooling profiles, respectively. The thermal stability of both FFA and PEG under these conditions has been discussed in previous work.16 The hot stage was calibrated measuring the melting point of water. Optical micrographs were recorded using a Nikon DS-Fi2 camera and NIS Elements BR software version 4.30.01. Once the CSDs were obtained, the microscope slides were stored in a desiccator as described above before further solid-state characterization was conducted. Every composition was prepared and characterized in triplicate.

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.
