Rabbit anti β actin monoclonal antibody

Manufactured by Merck Group
Sourced in United States

Rabbit anti-β-actin monoclonal antibody is a laboratory reagent used to detect and quantify the presence of the β-actin protein in biological samples. β-actin is a widely expressed cytoskeletal protein that is commonly used as a control for normalizing protein expression data in Western blotting and other applications.

Samples of 40 μg were resolved using 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis and blotted electrophoretically to polyvinylidene fluoride membranes. In brief, the membranes were incubated with primary antibodies, and immunoreactivity was detected using a horseradish-conjugated secondary antibody and visualized using enhanced chemiluminescence. The following primary antibodies were used: Mouse anti-HIF-1α antibody (1:1000, abcam, Burlingame, CA, USA ), rabbit anti-p75NTR monoclonal antibody (1:1000, Cell Signaling and Proteintech), rabbit anti-claudin-5 polyclonal antibody (1:500, Santa Cruz Biotechnology, Inc., Santa Cruz, CA, USA), goat anti-ZO-1 polyclonal antibody (1:500, Santa Cruz Biotechnology, Inc., Santa Cruz, CA, USA ), and, rabbit anti-β actin monoclonal antibody (1:500, Sigma Aldrich, St. Louis, MO, USA). For densitometry, data were normalized for the actin expression.

CD45CD71+ bone marrow erythroid cells were lysed and sonicated in lysis buffer (50 mM Tris (pH 7.4), 150 mM NaCl, 0.1% SDS and 1% Triton X-100) supplemented with protease inhibitor cocktail (Sigma-Aldrich). A total of 50 μg protein of the lysates was separated through 15% denaturing polyacrylamide gels and transferred to polyvinylidene difluoride membrane (Bio-Rad Laboratories). Primary antibodies used were a rabbit anti-caspase 3 polyclonal antibody (Cell Signaling Technology, Danvers, MA), a rabbit anti-LC3 polyclonal antibody (Abcam, Cambridge, UK) and a rabbit anti-β-actin monoclonal antibody (Sigma-Aldrich). Secondary antibody was used was a horseradish peroxidase conjugated goat anti-rabbit IgG (Sigma-Aldrich). The densitometric analysis was performed using ImageJ software (The National Institutes of Health, MD).

Protein preparation was performed as described previously (Mandhan et al., 2006a (link)): the cloaca/hindgut per condition were pooled and sonicated in ddH2O containing protease inhibitors. Protein extracts were seperated on SDS-PAGE electrophoresis, and transferred to PVDF membranes, blocked with 5% fat-free milk in Tris-buffered saline (2 h, room temperature). Membrane were incubated in primary antibody against Wif1 (diluted 1:500, Rabbit polyclonal, ab186845; Abcam, Cambridge, UK), β-catenin (diluted 1:1,500, mouse monoclonal, cat#610154; BD Biosciences, San Jose, CA, USA) or anti- β-Actin rabbit monoclonal antibody (1:2,000 dilution; Sigma, St Louis, MO, USA), and incubated with the secondary antibody (diluted 1:3,000, goat anti-rabbit or goat anti-mouse HRP conjugate; Jackson Immunoresearch, West Grove, PA, USA) Membranes were developed by using a chemiluminescent substrate kit (Pierce, Pierce, Rockford, IL, USA) and densitometric values were analyzed by using the ECL Plus detection system (Millipore, Billerica, MA, USA) (https://www.protocols.io/view/western-blot-analysis-kumcwu6).

Separated mononuclear cells (1×106) were lysed in 50 μl sample buffer containing 150 mM Tris Ph=6.8, 1.2% SDS, 200 mM 2-ME, 0.2% bromophenol blue and 33% glycerol on ice. The lysates were boiled for 10 min and then centrifuged at 17700×g for 20 min at 4°C. Thirty μl of cell lysates and 35 ng recombinant human PLAC1 (rhPLAC1) (produced in Dr. Zarnani's lab) were run on a 14% SDS-PAGE gel at 100 V for 2 hrs and then transferred to PVDF membrane at 200 mA for one hr. The existence of protein bands was visualized by Ponceau S staining. The membrane was blocked with PBS-0.1% Tween 20 (PBS-T) containing 5% skimmed milk solution overnight without shaking at 4°C. The membrane was then immunoprobed with rabbit anti-rhPLAC1 antibody (produced in Dr. Zarnani's lab) at 2 μg/ml in PBS-T containing 1% skimmed milk solution for 1.5 hr with shaking at RT followed by goat anti-rabbit IgG-HRP (1:6000) (Bio-Rad, Hercules, CA, USA) in PBS-T containing 1% skimmed milk solution for one hr with shaking at RT. After extensive washing, membrane was developed with ECL. Anti-β-actin rabbit monoclonal antibody (Sigma, St. Louis, USA) was used for visualization of β-actin after reprobing of the membrane.

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.
