Anti β actin ac 15

Manufactured by Abcam
Sourced in United States

Anti-β-actin (AC-15) is a mouse monoclonal antibody that recognizes the beta isoform of the actin protein. It can be used as a loading control in Western blotting applications to detect the ubiquitously expressed beta-actin, which is often used as a reference for data normalization.

Raw264.7 cell lines were cultured in DMEM (Gibco) supplemented with 10% FBS, 100 U/ml penicillin, 100 μg/ml streptomycin and 10 μg/ml gentamycin. One day prior to treatment, 1 x 106 cells/well were seeded on a 6-well plate. Cells were treated with 0, 0.2, 0.4, 0.8 mg/ml of lidocaine for 2 h and subsequently stimulated with LPS for 10 min. Cells were washed with cold PBS, lysed with NP–40 lysis buffer containing protease inhibitor cocktail (GenDepot) and incubated with continuous agitation at 4°C for 30 min. After centrifugation at 13,000 g for 15 min, supernatants were taken and 30 μg of protein were used for SDS-PAGE. Protein samples were transferred to Immobilon-P PVDF membrane (Millipore). The following antibodies were used for western blot analysis: anti-IκB-α (L35A5, 1:1000 dilution, Cell Signaling Technology), anti-β-actin (AC–15, 1:5000 dilution, Abcam), anti-mouse IgG-HRP (sc–2005, 1:5000 dilution, Santa Cruz Biotechnology).

DNA cell cycle analysis was performed using a detergent‐trypsin method and standard flow cytometry with a FACSCalibur cytometer (Becton Dickinson, San Jose, CA) and CELLQuest software. For the calculation of S‐phase fraction, ModFitLT 2.0 software (Verity) was used.
Cell survival after treatment with 5‐FU was evaluated using modified MTT assay with Cell Counting Kit‐8 (Dojindo Molecular Technologies, Inc., Tokyo, Japan).

Cells were harvested in radioimmunoprecipitation assay buffer (Thermo Fisher Scientific, Waltham, MA, USA) supplemented with a protease inhibitor cocktail (Roche Applied Science, Mannheim, Germany). The protein concentration was determined using a Pierce BCA Protein Assay kit (Thermo Fisher Scientific). Protein lysate (20 μg) was resolved in SDS-polyacrylamide gels, transferred to PVDF membrane and then probed with antibodies specific to: folate receptor alpha (FR-α) (ab125030; Abcam, Cambridge, MA, USA); Cyclin D1 (72-13G), CDK4 (C-22), and PARP-1 (H-250) (all from Santa Cruz Biotechnology, Santa Cruz, CA, USA); p21WAF−1 (12D1) and Bcl-2 (2876S) (both from Cell Signaling Technologies, Danvers, MA, USA); and Caspase-3 (610322; BD Transduction Laboratories, San Diego, CA, USA). The membranes were next incubated with the respective secondary antibodies (Thermo Fisher Scientific). Anti-β-actin (AC-15; Abcam) and anti-β-tubulin (T5293; Sigma-Aldrich, St. Louis, MO, USA) antibodies were used as internal loading controls. The protein bands were quantitated using ImageJ software.

Small-scale nuclear extracts were prepared from cells as described previously [110 (link)]. The following sequences were used to generate double-stranded oligonucleotides for EMSA: MEF-2 site from HTLV-1 LTR: 5′GAATAAACTAACAGGAGTCT3′ (biotinylated at 5′ end), MEF-2 consensus site from Glut4 promoter [111 (link)]: 5′GGGAGCTAAAAATAGCAG3′, MEF-2 consensus mutant: 5′GGGAGACGAAAACCGCAG3′ and Oct-1: 5′TGTCGAATGCAAATCACTAGAA3′ (biotinylated at 5′ end). Nonradioactive EMSA was performed using LightShift Chemiluminescent EMSA Kit (Thermo Scientific) according to the manufacturer’s instructions. Western blotting was performed essentially as described above. Whole-cell lysates were resolved by SDS-PAGE, transferred to nitrocellulose membranes, blocked in 5% milk, incubated with the indicated primary and secondary antibodies, and detected using Western Lightning enhanced chemiluminescence reagent (Perkin Elmer). Anti-FLAG M2 was purchased from Sigma. Anti-β-actin (AC15) was from Abcam.

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.
