Hrp conjugated igg antibody

Manufactured by Cell Signaling Technology
Sourced in United States

The HRP-conjugated IgG antibody is a laboratory reagent that consists of an immunoglobulin G (IgG) antibody covalently linked to the enzyme horseradish peroxidase (HRP). This conjugate is commonly used in various immunoassay techniques, such as enzyme-linked immunosorbent assays (ELISAs), to detect and quantify target proteins or other analytes in biological samples.

Cell lysates were prepared using Radio Immunoprecipitation Assay (RIPA) buffer (Sigma-Aldrich, St. Louis, MO, USA). Equal amounts of protein (20 μg protein/lane) were electrophoresed on a 10%-SDS-polyacrylamide gel and electrophoretically transferred to a polyvinylidene difluoride membrane (Millipore, Billerica, MA, USA). After blocking with 5% bovine serum albumin in Tris-buffered saline at room temperature for 1 h, the membranes were incubated with antibodies against IFITM1 (Proteintech Group Cat# 60074-1-Ig Lot# RRID:AB_2233405), IFITM2, IFITM3 (Proteintech Group Cat# 66081-1-Ig Lot# RRID:AB_11182821), and β-actin (Proteintech, Wuhan, Hubei, China) or HTNV NP (provided by the Department of Microbiology, The Fourth Military Medical University) overnight at 4°C. The membranes were then washed and incubated with HRP-conjugated IgG antibody (Cell Signaling Technology, Danvers, MA, USA) for 1 h at room temperature. The blots were developed using an enhanced chemiluminescence detection kit (Millipore, Billerica, MA, USA) and visualized using X-ray film. The blot densities were analyzed using the Quantity One software (Bio-Rad, Hercules, CA, USA). In addition, the RIPA buffer contains 50mM Tris (pH = 7.4), 150 mM NaCl, 1% Triton X-100, 1% sodium deoxycholate, 0.1% SDS. Protease inhibitor cocktail (Roche, Basel, Switzerland) was added before use.

Area Str. LM was dissected out of 2-4 hippocampal slices, pooled, and
homogenized in ice-cold lysis buffer containing phosphatase and protease
inhibitor cocktails (PPI; Sigma). Samples (5-7 μg) were loaded in sample
buffer (Laemmli; Sigma), boiled, and run on Bis-Tris gels (4-12% gradient;
Invitrogen). Following electrophoresis, proteins were transferred to PVDF
membranes, blocked and probed with the following antibodies: phosphorylated
CaMKII (1:3000; Abcam); phosphorylated serine-831 GluAl (1:1000; Sigma);
β-actin (1:5000; Cell Signaling). Membranes were incubated for 1hr at
room temperature in appropriate HRP-conjugated IgG antibodies (1:1000; Cell
Signaling) and imaged with enhanced chemiluminescence using the ChemiDoc XRS
system (BIORAD. Membranes were then stripped using Restore Western Blot
Stripping Buffer (15min; ThermoScientific), blocked, and re-probed with the
following antibodies: CaMKII (1:1000; Abcam); GluA1 (1:1000; Pierce)
Western blot images were analyzed using the ImageJ densitometry analysis
software (NIH; version 1.49). To determine the phosphorylation states of
proteins, protein bands were analyzed based on the ratio of phosphorylated
protein signal to total protein.

THP-1 cells were seeded in 6-well plates at 1.5 × 106 cells/mL. The cells were pretreated with or without LPS (1 μg/mL) for 1 h and then treated with ES (0, 12.5, 25, and 50 μg/mL) for 1 h. After incubation, the cells were harvested by centrifugation (1500 rpm, 5 min). Proteins were extracted by RIPA lysis Kit (Beyotime) containing phenylmethanesulfonyl fluoride (PMSF). Protein concentration in the supernatant was measured using BCA protein assay kit (Takara, Japan). Equal amounts of proteins were loaded on 10% SDS-polyacrylamide gel and transferred onto nitrocellulose membranes (Amersham Biosciences, UK). After blocking in Tris-buffered saline with 0.05% Tween 20 (TBST) containing 5% nonfat milk for 1.5 h, the membranes were incubated with primary antibodies (Cell Signaling Technology) at 4°C overnight. After washing, the membranes were incubated with HRP-conjugated IgG antibodies (Cell Signaling Technology) for 1 h. Membranes were developed using ECL Western blotting detection reagent (Bio-Rad).

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.
