Anti rabbit igg conjugated to horseradish peroxidase

Manufactured by Santa Cruz Biotechnology
Sourced in United States

Anti-rabbit IgG conjugated to horseradish peroxidase is a laboratory reagent used as a detection tool in various immunoassay techniques. It consists of rabbit immunoglobulin G (IgG) molecules covalently linked to the enzyme horseradish peroxidase (HRP). This conjugate can be utilized to detect and visualize the presence of rabbit-derived antibodies in biological samples.

All fractions were mixed with the equal volume of the 2X sample loading buffer (125 mM Tris-HCl, 4% (w/v) SDS, 20% (v/v) glycerol, and 0.01% (w/v) bromophenol blue) with dithiothreitol and boiled for 10 min. Mixtures were briefly centrifuged prior to loading, electrophoresed through 10% SDS-polyacrylamide gels, and electro-transferred to a polyvinylidene difluoride (PVDF) membrane. The membrane was blocked with 1X TBS-T (137 mM NaCl, 27 mM KCl, 250 mM Tris-HCl, and 0.1% Tween-20) containing 5 % (w/v) skim milk for an hour at room temperature prior to incubating with an anti-GFP, anti-RFP (dilution: 1:1000; Santa Cruz Biotechnology, Dallas, TX, USA) or anti-CP antibody (CTV-908 [35 (link)]; dilution: 1:500) with 1X TBS-T for another hour. Anti-rabbit IgG conjugated to horseradish peroxidase was used as a secondary antibody (dilution: 1:20,000; Santa Cruz Biotechnology, Dallas, TX, USA), and the signal was visualized on chemiluminescence film (X-OMAT LS; Carestream Health Rochester, NY, USA) in a dark room (Carestream Kodak, Sigma-Aldrich, St. Louis, MO, USA).

Characterizing TAZ and Integrin Signaling

The tissues were homogenized in RIPA buffer (Sigma) and the total protein concentrations of the homogenates were measured using the BCA reagent. Equal amounts of protein were subjected to SDS-PAGE and transferred to polyvinylidene difluoride membranes by electroblotting. After blocking, the membranes were incubated with antibodies against human TAZ (Abcam), human β1 integrin (Abcam), and β-actin (Cell Signalling Technology).
ME180 cells were grown on 100‐mm culture dishes until they reached 80% confluency and then incubated with su6656, an inhibitor of the Src family of kinases (1 μ M) (Calbiochem. Calif., USA), or a vehicle control (DMSO) for 1 hr. The lysates were prepared in RIPA buffer. The cytosolic and nuclear extracts were obtained using NE-PER nuclear and cytoplasmic extraction reagents (Thermo Fisher, Waltham, MA). Equal amounts of protein were subjected to SDS-PAGE and transferred to polyvinylidene difluoride membranes by electroblotting. After blocking, the membranes were incubated with primary TAZ antibodies (Abcam). The secondary antibody was an anti-rabbit IgG conjugated to horseradish peroxidase (Santa Cruz Biotechnology, Inc., Santa Cruz, CA), diluted 1:2000 and incubated with the membrane for 1 h. The protein bands were detected using enhanced chemiluminescence plus detection system according to the manufacturer's instructions (BioRad).

GnRH-(1–5) was purchased from Bachem (Torrance, CA, USA) and reconstituted to 10 mM in distilled water and stored in 12 µL aliquots at −80°C. GN11 cells (18 (link)) generously donated by Dr. Sally Radovick (Robert Wood Johnson Medical School, Rutgers University, New Brunswick, NJ, USA) were grown in Dulbecco’s modified Eagle’s medium (DMEM; Mediatech Inc., Herndon, VA, USA) without antibiotics and supplemented with 7% fetal bovine serum (FBS; Hyclone, Logan, UT, USA), 3% newborn calf serum (Hyclone), 25 mM glucose, and 5 mM l-glutamine (7 (link), 11 (link), 19 (link)). Cells were maintained at 37°C in an atmosphere with 5% CO2. In addition, all experiments were conducted at 37°C in an atmosphere with 5% CO2. All GN11 cells used for experimentation were below passage 25. GN11 cells originated from an olfactory tumor extracted from a male mouse (18 (link)). The antibodies used in this study were specific for the TGF-βRI (1:1,000; Cat. No. SC-9048, Santa Cruz Biotechnology, Dallas, TX, USA), TGF-βRII (1:1,000; Cat. No. SC-400, Santa Cruz Biotechnology), GAPDH (1:2,000; Cat. No. SC-25778, Santa Cruz Biotechnology), and anti-rabbit IgG conjugated to horseradish peroxidase (1:10,000; Cat. No. 170-6515, Bio-Rad, Hercules, CA, USA).

Cells were washed and lysed in 0.15 ml cell extraction buffer (Invitrogen). Equivalent amounts of protein were solubilized in 2× SDS sample buffer, separated on 10% SDS-polyacrylamide gels, transferred onto nitrocellulose membrane, blocked with 5% nonfat dry milk containing 0.1% Tween 20 for 1 h at room temperature, and washed thrice with wash buffer (1×TBST). Blots were incubated with primary antibodies against AP-2α, α7 nAChR at 1:1000 dilution, or EP4 (1:4000), overnight at 4°C, then washed thoroughly, and incubated with secondary anti-rabbit IgG conjugated to horseradish peroxidase (1:2,000 dilution; Santa Cruz) for 1 h at room temperature. Blots were stained by ECL regents (Amersham Life Science) and exposed to X-ray film, and proteins were quantified by densitometric scanning using a Bio-Rad GS-800 calibrated densitometer.

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.
