Anti hmgb1 antibody

Manufactured by Novus Biologicals
Sourced in United States

The Anti-HMGB1 antibody is a laboratory reagent used for the detection and analysis of HMGB1 (High Mobility Group Box 1) protein in various biological samples. HMGB1 is a nuclear protein involved in DNA binding and transcriptional regulation. This antibody can be used in techniques such as Western blotting, immunohistochemistry, and ELISA to study the expression and localization of HMGB1 in cells and tissues.

Immunofluorescence Staining of Cultured Cells

Cultured cells were fixed with 2% PFA (Electron Microscopy Sciences) in PBS (Crystalgen) for 15 min after washing with HBSS and quenched with 0.1 M glycine (Sigma-Aldrich) in PBS. For intracellular staining, the cells were treated with 0.1% Triton X-100 (Fisher Scientific) in 1% BSA (Roche) in PBS for 5 min. Cells were blocked with 10% goat serum (Sigma-Aldrich) in PBS for 1 h, and then stained for 1 h with primary antibody diluted in 3% BSA in PBS. After washing, cells were stained with fluorescent-conjugated secondary antibody for 30 min. Cells were washed with PBS, stained with DAPI, and mounted with fluorescent mounting medium (Dako). All procedures were performed at room temperature. Anti-MAP2 antibody (Sigma-Aldrich), anti-postsynaptic density protein 95 (PSD-95) antibody (Millipore), anti-NMDAR subunit 1 extracellular (GluN1) antibody (Alomone Labs), antiHMGB1 antibody (Novus), and anti-C1q antibody (Abcam) were used for immunofluorescence staining. Secondary antibodies, Alexa Fluor Goat anti-Mouse antibody and Goat anti-Rabbit antibody (Life Technologies) were used following primary antibody staining.

Modulating HMGB1 for Nerve Regeneration

Check if the same lab product or an alternative is used in the 5 most similar protocols
To investigate the associations among HMGB1, the inflammatory reaction, and nerve regeneration after injury, the anti-HMGB1 antibody (Novus Biologicals, USA) was injected intraperitoneally just after the NTx. To determine if there is a dose-dependent effect of the drug, low (25 μg in 0.5 ml saline) and high (50 μg in 0.5 ml saline) doses of the anti-HMGB1 antibody were used, making them comparable to a dose used in a previous study [25 (link)]. We also injected IgG (50 μg in 0.5 ml saline) intraperitoneally in a group of control animals. We collected data from six mice for each of the three treatment groups and each of the four recovery time points (days 5, 14, 42, and 100) for a total of 72 mice (6 mice × 3 doses × 4 recovery points).

Immunoblotting Analysis of Cochlear Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
Aliquots of cochlea homogenates were separated on 8% sodium dodecyl sulfate (SDS) polyacrylamide gels, transferred to polyvinylidene difluoride (PVDF) membranes (Millipore, Billerica, MA, USA), blocked with 5% skimmed milk in TBST (0.2 M Tris-base, 1.37 M NaCl, and 0.1% Tween 20), probed with the indicated primary antibody at 4 °C overnight, washed with TBST, and incubated with anti-rabbit horseradish peroxidase-linked whole antibody (1:10,000; GE Healthcare, Chicago, IL, USA) for 1 h at RT. The immunoreactive bands were stained using a light emitting nonradioactive method (ECL; Millipore). The specific primary antibodies were anti-HMGB1 antibody (1:1000; Novus Biologicals, Littleton, CO, USA), anti-4-HNE antibody (1:1000; Abcam, Cambridge, UK), and anti-actin antibody (1:1000; Millipore, Burlington, MA, USA).

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.
