High Mobility Group 1 (HMGB1) Isoforms Kit

- Overview
  - HMGB1 Isoforms Kit is an explorative kit thought to test different redox isoforms of HMGB1.
    The kit contains 3 different isoforms of HMGB1:
    • Fully reduced HMGB1
    • Disulfide HMGB1
    • Terminally oxidized HMGB1
    
    Different activities of HMGB1 have been attributed to different biochemical forms that bind to specific receptors (Yang et al.,2012).
    
    • Fully reduced HMGB1 has all the three cysteines completely reduced and is a potent chemoattractanct for many cell types by forming a heterocomplex with the chemokine CXCL12 and signaling via CXCR4 (rif PMCID: PMC3302219 ).
    • Disulfide HMGB1 contains a disulfide bond between cysteines C23 and C45 and acts as a proinflammatory mediator by binding to TLR4 and RAGE receptors (Yang et al, 2012; Tirone et al, 2018).
    • Terminally oxidized HMGB1 has all the cysteines oxidized to sulfonates and has no activity, either as a chemoattractant or in cytokine stimulation (Kazama et al,2008;Yang et al, 2012).It can be useful as negative control in your experiment.
    The proteins we provide are the natural proteins, with no tags or additional amino acids.

    Molecular Mass: HMGB1 consists of 215 amino acid residues and has a calculated molecular mass of approximately 24.8 kDa. It migrates at a position of approximately 30 kD in SDS-PAGE gels, possibly because of the unusual number of positively charged amino acids it contains.
    Structure: HMGB1 consists of two fairly rigid, L-shaped DNA-binding domains, each referred to as a 'HMG box', and an unstructured tail that ends with 30 consecutive negatively charged amino acids.
    Species specificity: the sequence and structure of HMGB1 have been strictly conserved during evolution, and HMGB1 proteins from all mammals are almost identical (Sessa L, Bianchi ME. The evolution of High Mobility Group Box (HMGB) chromatin proteins in multicellular animals. Gene 2007, 387:133-40).
    Purity: The purified protein is >95% homogeneous (electrophoresis). It contains no nucleic acids.
    Endotoxin Level: The purified protein is free from LPS (Pierce™ Chromogenic Endotoxin Quant Kit, <0.1 EU/mL). The product contains <0.006% v/v of Triton X-114 due to LPS removal procedure. The remaining traces of Triton X-114 can be removed upon request.
    Buffer & Reconstitution: the lyophilized proteins once reconstituted with distilled water will be dissolved in a solution containing 50 mM HEPES pH 7.9, 500 mM NaCl.
    
    Storage: 2-8°C. Once the proteins are resuspended they can be stored frozen (-20°C).
