General description

Anti-HMGB1 (HMG1) (N-terminal) is produced in rabbit using as immunogen a synthetic peptide corresponding to human HMGB1 conjugated to KLH. High Mobility Group B (HMGB) protein family includes HMGB1, HMGB2 and HMGB3, that are highly conserved and indistinguishable in their biochemical properties. HMGB1 is a 25 kDa protein of 215 amino acids and consists of two homologous HMG-boxes rich in basic amino acids, and an acidic tail at the carboxy-terminus.
HMGB proteins belong to the High Mobility Group (HMG) family of proteins that contain the HMG-box for binding and changing DNA structures .

Immunogen

synthetic peptide corresponding to amino acids 2-17 of human HMGB1, conjugated to KLH. The corresponding sequence is conserved in mouse and rat.

Application

Anti-HMGB1 (HMG1) (N-terminal) antibody is suitable for use in chemiluminescent immunoblot (using mouse heart homogenates) . The antibody can also be used in immunoprecipitation (10 μg using HEK-293T cell lysates), indirect immunofluorescence (1-2 μg/mL using paraformaldehyde-Triton fixed PC12 cultured cells), and western blot (1-2 μg/mL using 3T3 cell lysates).
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Biochem/physiol Actions

High Mobility Group B (HMGB-1 and 2) participate in the regulation of chromatin structure as well as being involved in transcription regulation, DNA repair, recombination, differentiation and extracellular signaling. It shows a defect in transcriptional enhancement of the glucocorticoid receptor, that indicates the important role for HMGB1 in proper transcriptional control by specific transcription factors. Increased expression of HMGB1 is observed in cancer cells.
