-
特异性
- 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.
-
交叉反应 （详细）
- the sequence and structure of HMGB1 have been strictly conserved during evolution, and HMGB1 proteins from all mammals are almost identical.
-
产品特性
- Fully reduced-HMGB1 we provide is the natural protein, with no tags or additional amino acids.
-
纯化方法
-
Purified
Oxidation of cysteine 106 makes the protein inactive. To avoid cysteine oxidation, DTT 0.5 mM is added during protein purification. -
内毒素水平
- LPS free: (Pierce™ Chromogenic Endotoxin Quant Kit, <0.1 EU/mL).
-
Biological Activity Comment
- Measured by its ability to induce migration. Maximal activity in the cell migration assay is obtained at 1 nM, or 25 ng/ml (Palumbo et al. 2004).

背景
-
HMGB1 is a nuclear protein that is released passively by necrotic cells, retained by apoptotic cells, and secreted actively by inflammatory cells.
HMGB1 is a nuclear protein that is released passively by necrotic cells, retained by apoptotic cells, and secreted actively by inflammatory cells.
HMGB1 is essential for life: Hmgb1 knockout mice die shortly after Birth (Dumitriu et al. 2005).
The two different activities of HMGB1 as a chemoattractanct of motile cells and as inducer of cytokines have been attributed to different biochemical forms.
Fully reduced HMGB1 complete notation: HMGB1C23hC45hC106h – Antoine J.,2014) is completely reduced and has chemoattractanct activity; Disulfide HMGB1 contains a disulfide bond between C23 and C45 (complete notation: HMGB1C23-C45C106h – Antoine J.,2014) and can induce cytokine and chemokine production in monocytes and other inflammatory cells.
Fully reduced HMGB1, also known as ReHMGB1, had previously been sold as Chemotaxis-HMGB1 LPS free and tested in migration assay, but is otherwise the same identical product.
Fully reduced HMGB1 behaves as a trigger of inflammation, attracting inflammatory cells, and of tissue repair, attracting stem cells and promoting their proliferation. Moreover, Fully reduced HMGB1 activates dedritic cells and promotes their functional maturation and migration to lymph nodes.
However, and contrary to early reports, pure Fully reduced HMGB1 does not promote cytokine secretion. Cytokine secretion is only promoted by disulfide HMGB1 (the form containing disulfide bond). -
