NASBA Band Visualization on PAGE

Check if the same lab product or an alternative is used in the 5 most similar protocols
Samples to be visualized on PAGE were mixed with three volumes formamide supplemented with 20 mM EDTA and then heated for 5 min to 90°C. Samples were then loaded and run into 8% PAGE (19:1 Acrylamide:bis). Post staining of the gels was performed using 100 mL of 1× WB (140 mM KCl, 1 mM MgCl2, 10 mM NaH2PO4 pH 7.2, 0.05% Tween-20) supplemented with 20 nM TO1-Biotin, and Mango NASBA bands were imaged on a GE AI600RGB imager as described elsewhere (Yaseen et al. 2019 (link)). Alternatively, gels were stained with 1× SYBR Safe stain otherwise under the same conditions.

Western Blot Analysis of Protein Expression

BMECs were washed thrice with PBS and lysed in cold radioimmunoprecipitation assay lysis buffer containing a protease inhibitor cocktail (P8340, Sigma-Aldrich, St. Louis, MO, USA) on ice for 30 min. Lysates were centrifuged at 12,000× g for 15 min. Protein concentration in the supernatant was measured by the Bradford assay method. Proteins were then boiled for 10 min and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). For gel electrophoresis, 15 µg of total protein extracts was separated on 12.5% SDS-PAGE gel and then transferred to an Immuno-Blot polyvinylidene fluoride (Millipore, Temecula, CA, USA) membrane through wet transfer apparatus (BioRad, Hercules, CA, USA) for 1.5 h, at a 300 mA constant current. The membrane was incubated for 1 h with 5% non-fat dairy milk, washed thrice for 10 min, and the primary antibodies were probed overnight at 4 °C. The membranes were washed and probed with horseradish peroxidase (HRP) goat anti-rabbit IgG antibody and HRP goat anti-mouse IgG antibody for 1 h at 25 °C. Thereafter, chromogenic-enhanced chemiluminescence was performed. An AI600RGB imager (GE, Fairfield, CT, USA) and ImageLab 6.1 software (BioRad, Hercules, CA, USA) were used to reveal and analyze the chemiluminescence signal.

Immunoblot Analysis of Adult Brain Tissue

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunoblot samples of adult brain tissue and hippocampal slice cultures were sonicated in cold lysis buffer (Sigma-Aldrich; St. Louis, Missouri). Protein content was determined and equal amounts of protein were denatured in sample buffer and separated on gradient gels for subsequent transfer to nitrocellulose. Blots were incubated in blocking solution containing 5% milk or BSA for 1 h. Primary antibody staining utilized antibodies against cathepsin B (1:100, Calbiochem), GluR1 (1:1000; Millipore) and anti-αII spectrin (1:100, Santa Cruz), as well as against actin 20–33 (1:500, Sigma) and an antibody to gephyrin’s C-terminal (1:250) made against the sequence VELHKGEVVDVMVIGRL described in Kawasaki et al. (1997) (link). Anti-IgG-alkaline phosphatase conjugates and anti-IgG-horseradish peroxidase conjugates were used for the secondary antibody step, and antigen staining and image development involved the chemiluminescence protocols using the GE Amersham AI600RGB imager. Immunostained bands were scanned at high resolution to determine integrated optical density with BIOQUANT software (R & M Biometrics, Nashville, Tennessee).

Investigating EphA2 and EphA3 Downregulation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The downregulation of EphA2 and EphA3 was investigated as described previously.43 (link) Western blots for testing the presence of receptors were also performed as described previously.9 (link) Three independent experiments were performed for each QUAD version and the EphA2 and EphA3 receptors. Density of immunoreactive bands was measured on an AI600 RGB imager (GE). Data from 3 independent experiments were normalized to the corresponding β-actin and analyzed in Prism GraphPad.

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.
