Protein Expression Analysis in HCT-116 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
HCT-116 cells were collected and lysed in radio immunoprecipitation assay (RIPA) lysis buffer (Sigma-Aldrich) containing protease inhibitors and phosphatase. Protein concentration of the lysates was quantified using the bicinchoninic acid Protein Assay Kit (Jiancheng Bioengineering Institute, Nanjing, Jiangsu, China). The proteins were separated by 10% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) at 110 V for 2 h and then transferred onto a polyvinylidene fluoride membrane (Millipore, Boston, MA, USA) at 60 V for 2 h. After blocking with 5% nonfat milk at room temperature for 1 h, the polyvinylidene fluoride membranes were incubated with anti-Bcl-2 (1:1,000; Abcam, Cambridge, UK), anti-Bax (1:1,000; Abcam), anti-p-Akt1 (1:1,000; Abcam), anti-P-ERK (1:1,000; Abcam), and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) (1:1,000; Abcam) primary antibodies overnight at 4°C. The polyvinylidene fluoride membranes were washed with tris buffered saline tween (TBST) and incubated with a horseradish peroxidase–conjugated secondary antibody at room temperature for 45 min. Visualization was performed with a chemiluminescent detection kit (Millipore). The densitometry of the bands was analyzed using Gel-Pro 6.3 software (Media Cybernetics, Inc., Bethesda, MD,USA).

Proteins were extracted from more than 106 harvested BMSCs according to the kit protocol (KeyGen Biotech, China). [46 (link)] BMSCs were digested in a lysis buffer cocktail and centrifuged at 12000 g for 15 minutes at 4 °C to get the supernatant as the total protein. 10% sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) was used for electrophoresis of protein (20 μg) with loading buffer and then blotted to a polyvinylidene fluoride (PVDF) membrane (Millipore Co., USA). Membranes were blocked with 5% skimmed milk in Tris-buffered saline tween 20, TBST, and then incubated overnight at 4°C with primary antibodies; anti-IHH, anti-P53, anti-P16, anti-PI3K, anti-p-PI3K, anti-Akt 1, anti-p-Akt 1, anti-NF-κB, anti-p-NF-κB-p65, anti-STAT3, anti-p-STAT3, anti-4EBP1, anti-p- 4EBP1, anti-p70S6K, anti-p-p70S6K and anti-β-actin (1:1000), all from Abcam, USA. The membranes were incubated for 1hour at RT with secondary antibody conjugated with horseradish peroxidase. Finally, TBST-washed membranes were treated with enhanced chemiluminescent (ECL) for detection (Bio-Rad, USA). Image Lab detection system (Bio-Rad, USA) was used for protein bands imaging and analysis.

Immunohistochemical Analysis of Ectopic Endometria

Check if the same lab product or an alternative is used in the 5 most similar protocols
Rats’ ectopic endometria fixed in a 4% neutral paraformaldehyde solution, were washed, dehydrated, waxed, and embedded. Slides, soaked in a wash buffer over-night, were rinsed with running water and dried. After being immersed in 100 pg/ml polylysine for 30 min at 37°C, the slides were inserted into a clean glass shelf overnight at 37°C. A microtome was used to cut 4-μm-thick serial sections, and 5 of these sections were selected to sit for 1 h at 56°C and then over-night at 37°C. Before staining, the sections were placed in a 60°Cwarm case for 1 h. Sections were then dewaxed in xylene and rehydrated, followed by microwaving in 10 mM sodium citrate buffer (pH 6.0) for antigen retrieval. The sections were washed three times with PBS (0.01 mmol/L, pH 7.4) for 3 min. The immunohistochemistry S-P method was conducted according to the manufacturer’s instructions (Maixin-Bio Corporation, Fuzhou, China). The dilution ratio of anti-VEGF, anti-VEGF-2 and anti-p-Akt1(Abcam) was 1:200. The dilution ratio of anti-Akt1, anti-mTOR(Abcam), and anti-p-mTOR (Cell Signaling Technology) was 1:100.

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.
