General description

High-mobility group-1 protein (HMG-1) or amphoterin is a nuclear DNA-binding protein that facilitates the bending and transcription of DNA. It also has a pivotal role in the regulation of chromatin structure, DNA replication, ligation and repair. Monoclonal anti-HMG-1 antibody can be used as a vital tool to study the biology of transcription. It can also be used in indirect ELISA and immunoblotting (25kD approx.). Mouse anti-HMG-1 antibody reacts specifically with HMG-1 of canine, mouse, chicken, rat and human.
Monoclonal Anti-HMG-1 (mouse IgG1 isotype) is derived from the HAP46.5 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mouse immunized with purified human recombinant HMG-1. HMG-1 (High-Mobility-Group protein, amphoterin) is a highly conserved protein with more than 95% amino acid identity between rodent and human HMG-1. It is a prevalent non-histone chromatin component and a non-sequence specific DNA binding protein. HMG-1 consists of two homologous HMG boxes rich in basic amino acids and an acidic tail at the carboxy-terminus.


purified recombinant human HMG-1.


Monoclonal Anti-HMG-1 antibody is suitable for use in immunochemical applications such as ELISA and immunoblotting (approx. 25 kDa).
Monoclonal anti-HMG-1 antibody can be used in immunofluorescent staining. It can also be used in microarray and western blotting.

Biochem/physiol Actions

High-Mobility-Group protein, amphoterin, HMG-1 is involved in the regulation of chromatin structure as well as being involved, either as positive or negative factors with various aspects of DNA replication, transcription, repair, and ligation. HMG-1, identified as a membrane associated protein termed “amphoterin,” mediates neurite outgrowth, tumor outgrowth, and metastasis. It participates in plasminogen activation and is recognized as a late mediator of endotoxin lethality in mice.


Monoclonal Anti-HMG-1 recognizes human, canine, mouse, rat, and chicken HMG-1.
