Hrp conjugated anti mouse igg secondary antibody

Manufactured by GE Healthcare
Sourced in United States

The HRP-conjugated anti-mouse IgG secondary antibody is a laboratory reagent used to detect the presence of mouse immunoglobulin G (IgG) in various assays and experiments. The antibody is conjugated with horseradish peroxidase (HRP), which allows for colorimetric or chemiluminescent detection of the target mouse IgG.

Quantitative BteA Protein Analysis

Yeast cells harboring pYC2-CT derivatives encoding BteA-GFP fusion proteins were cultivated in SC-Ura-galactose media for 2, 5, and 20 h to induce the BteA expression. Equivalents of OD600 = 1 of yeast cell cultures were collected and denatured yeast protein extracts were prepared by NaOH lysis/TCA precipitation method according to Volland et al. 1994 [41 (link)]. Equal amounts of protein extracts were separated by SDS-PAGE electrophoresis (10% gel) followed by the transfer onto a nitrocellulose membrane. Membranes were probed overnight with mouse polyclonal antibodies raised against BteA (dilution 1:10,000, kindly provided by Branislav Vecerek, Institute of Microbiology, Prague, Czech Republic) or mouse monoclonal antibody against yeast phosphoglycerate kinase PGK1 (anti-PGK1, dilution 1:5,000, Abcam, ab113687) as a loading control. The detected proteins were revealed with 1:3,000-diluted horseradish peroxidase (HRP)-conjugated anti-mouse IgG secondary antibody (GE Healthcare) using a Pierce ECL chemiluminescence substrate (Thermo Fisher Scientific, USA) and an Image Quant LAS 4000 station (GE Healthcare, USA).

Viral vectors (0.3–0.5 μg protein) were separated on a 12% Bis-Tris NuPAGE gel (Life Technologies Corporation, Carlsbad, CA) under reducing conditions. Proteins were transferred to nitrocellulose (GE Healthcare Biosciences, Pittsburgh, PA). Immunoblot analysis of envelope proteins was performed with anti-Sindbis ascites fluid (ATCC, Manassas, VA) and HRP-conjugated anti-mouse IgG secondary antibody (GE Healthcare Biosciences). Biotinylation of envelope proteins was detected using HRP-conjugated NeutrAvidin® (Thermo Fisher Scientific). Protein bands were visualized using Chemiglow and Alpha Innotech FluorChem Imaging System (ProteinSimple, Santa Clara, CA).

5-mC dot blot assays were performed as previously described (Cai et al., 2017 (link)). Briefly, genomic DNA was extracted using the Wizard Genomic DNA Purification Kit (Promega) and diluted in TE buffer. The DNA samples were denatured in 0.4 M NaOH/10 mM EDTA at 95 °C for 10 min, and immediately neutralized with equal volume of ice-cold 2 M NH4OAc (pH 7.0). The samples were spotted on a pre-wetted nitrocellulose membrane in two-fold serial dilutions using a Bio-Dot Apparatus Assembly (Bio-Rad). The membrane was rinsed briefly in 2x SSC, baked at 80 °C for 2 hours, blocked in 5% non-fat milk for 1 hour at room temperature and incubated with anti-5-mC antibody (Diagenode, C15200081, 1:300) at 4 °C overnight. The membrane was washed in TBST (5 × 5 min), incubated with HRP-conjugated anti-mouse IgG secondary antibody (GE, 1:5000) for 1 hour at room temp, incubated with ECL substrate (Pierce), and developed.

For detection of PrPSc, brain homogenates and cell lysates treated with PK (20 μg PK/mg proteins; Wako Pure Chemical Industries) at 37 °C for 30 min. Total proteins were separated by 15% SDS-polyacrylamide gels and then electrically transferred onto an Immobilon-P PVDF membrane (Millipore Corp). The membrane was blocked with 5% nonfat dry milk in TBST (0.5% Tween-20, 150 mM NaCl, 10 mM Tris-HCl, pH7.4) for 1 h at room temperature and then incubated with SAF61 mouse monoclonal antibody (Bertin Pharma), 3F4 mouse monoclonal anti-PrP antibody (BioLegend), IBL-N rabbit polyclonal anti-PrP antibodies (Immuno-Biological Laboratories), and anti-GAPDH antibody (Santa Cruz Biotechnology) overnight at 4 °C. After washed three times in TBST, the membrane was then incubated with HRP-conjugated anti-mouse IgG secondary antibody (GE Healthcare), anti-rabbit IgG antibody (GE Healthcare) in 1% nonfat dry milk-containing TBST for 1 h at room temperature. The immunoreactive signals were detected using Immobilon Western Chemiluminescent HRP substrate (Millipore) and a chemiluminescence image analyzer (LAS-4000 mini; Fujifilm Co). Densitometric analysis was performed using Image Gauge software (Fuji Film).

HEK-293S cells were transfected with GPCR and FLAG-RAMP/pcDNA3.1 at a 1:1 ratio. Cell surface expression of FLAG-RAMPs was determined as previously described 22 . Briefly, 48 hours posttransfection, cells were fixed with 3.7% paraformaldehyde and washed 3 times with PBS before and after incubation with mouse anti-FLAG M2 primary antibody (Sigma, diluted 1:2000 in PBS with 1% BSA) or HRP-conjugated anti-mouse IgG secondary antibody (GE Healthcare, diluted 1:4000 in PBS with 1% BSA). Cells were then incubated in o-phenylenediamine (OPD) solution (SigmaFast ophenylenediamine tablets, Sigma, dissolved in 20 ml distilled water) for 3-5 min, before termination of the reaction by addition to 100 μL 1 M sulphuric acid. Plates were read using a Mithras LB 940 multimode microplate reader at 492 nm. Data were normalised to cell surface expression for cells co-transfected with CLR and RAMP2 as 100% and cells transfected with pcDNA3.1 as 0%.

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.
