Whole cell lysates were prepared in RIPA buffer from BCL as previously described (Mostafa et al., 2014). Proteins were quantified using a Pierce BCA Protein Assay Kit (Thermo Scientific, #23225) and reduced with 2‐mercaptoethanol (Gibco, #21985023). RAD51C protein expression was assessed in BCL whole cell lysates by electrophoresing 25 µg of protein by 10% SDS‐PAGE, followed by western blotting. Membranes were blocked in 5% milk powder in TBS‐Tween (0.15 M NaCl, 0.05 M Tris pH 7.4, 0.05% Tween 20) for 1 hr and incubated overnight with 4 µg/ml monoclonal mouse anti‐RAD51C (2H11) antibody (Santa Cruz Biotechnology, #sc‐56214) or 250 ng/ml mouse anti‐alpha tubulin (B‐7) antibody (Santa Cruz Biotechnology, #sc‐5286) at 4°C. Antibody binding was detected with 1:10,000 dilutions of horseradish peroxidase‐conjugated goat anti‐mouse secondary antibody (Jackson Immunoresearch, #115‐036‐071) and Clarity Western ECL substrate (Bio‐Rad, #1705060). Immunoreactivity was visualized and quantified by scanning densitometry using an ImageQuant LAS 4000 and ImageQuant TL Software v8.1, respectively (GE Healthcare). Five independent experiments were performed, and RAD51C protein expression was normalized to that of alpha tubulin.

Primary antibodies were obtained from the DSHB, mouse anti-actin (JLA20) 1:1000, or from Torrey Pines Biolabs, rabbit anti-GFP 1:2000. Horseradish peroxidase-conjugated goat anti-mouse secondary antibody (Jackson ImmunoResearch Laboratories, Inc., West Grove, PA) was used at 1:5000 for actin blots. Horseradish peroxidase-conjugated goat anti-rabbit secondary antibody (Jackson ImmunoResearch Laboratories, Inc., West Grove, PA) was used at 1:5000 for GFP blots. All antibodies were diluted in blocking buffer. Blots were developed with Super-Signal West Pico Chemiluminescent Substrate (Thermo Scientific, Waltham, MA) and imaged with Amersham Hyperfilm ECL film (GE Healthcare Limited, Buckinghamshire, UK). Band intensity was quantified using ImageJ.

Total protein lysates were extracted and Western blot analysis was performed as previously described [88 (link)]. Following extraction, protein concentration was determined by the Bradford protein assay (Bio-Rad, Hercules, CA, USA). Proteins were resolved on 7% polyacrylamide gels and blotted onto a Protran BA83 cellulose nitrate membrane (Whatman, GE, Maidstone, UK), and reacted with an anti-P-gp monoclonal antibody (JSB-1, kindly provided by Dr. G. Scheffer, VU Medical Center, Amsterdam, The Netherlands). The membrane was then reacted with a horseradish peroxidase-conjugated goat anti-mouse secondary antibody (Jackson Immunoresearch Labs, West Grove, PA). The membrane was stripped off and finally reacted with an anti-α-tubulin antibody for evaluation of actual loading (Sigma Aldrich, St. Louis, MO, USA). Quantification of the protein bands was performed using the EZ-Quant software (EZ-Quant, Tel-Aviv, Israel).

Immunohistochemistry was performed according to previously described methods using a normal light microscope (magnification, ×400) (28 (link)). Paraffin-embedded tissues from surgery were deparaffinized and pretreated in a microwave.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Adenovirus containing mouse extracellular domain (GUCY2C1-429) with the influenza HA107-119 CD4+ T-cell epitope known as site 1 (S1) was described previously (Ad5-GUCY2C-S1).20 (link) Here, GUCY2C-S1 was cloned into pShuttle and subcloned into the E1 region of previously generated replication-deficient chimeric adenovirus (Ad5.F35) in which the Ad5 fiber was replaced by the Ad35 fiber22 (link) to generate Ad5.F35-GUCY2C-S1. All adenovirus vaccines used in this study were produced in HEK293 cells and purified by cesium chloride ultracentrifugation under Good Laboratory Practices by the Baylor College of Medicine in the Cell and Gene Therapy Vector Development Lab and certified to be negative for replication-competent adenovirus, mycoplasma, and host cell DNA contamination. In vitro GUCY2C-expression experiments (dose–response and time–course) were carried out in A549 (American Type Culture Collection (ATCC)) cells. Virus was added to the cultures at the indicated doses and culture supernatants were collected at the indicated time points. Relative GUCY2C levels were quantified in supernatants by western blot using 2 μg/mL MS7 mouse anti-GUCY2C monoclonal antibody23–25 (link) and 0.1 μg/mL horseradish peroxidase-conjugated goat antimouse secondary antibody (Jackson Immuno).

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.
